Description
Technical field
The present invention relates to vegetable breeding fields, and in particular to a kind of tender flower stalk germ plasm resource for being suitble to disposable harvest operation
Method for creating, the tender flower stalk germ plasm resource can carry out disposable harvest operation mechanically or manually when just entering the early flowering season.
Background technique
Recently as the continuous improvement of labor cost, the cost to plant vegetables is higher and higher, is substituted using machinery artificial
The overall process for completing vegetables production is one of important trend of scientific research and innovation.Tender flower stalk is a kind of whole machine of most possible realization
One of the vegetable species of tool operation, but the character of current kind cannot entirely appropriate mechanical whole operation demand, main bottle
Neck is in harvest link.Existing tender flower stalk kind is that breeding obtains under the conditions of artificial Multiple harvests, be according to field single plant at
The different of ripe degree successively repeatedly harvest, and yield can be only achieved peak.And prior art machinery is only possible to disposably harvest, and shows
And if be clear to it is disposable early receive, population yield is also not up to peak, if evening receives, necessarily has part to bloom and excessively loses quotient
Moral character, population yield are also necessarily remarkably decreased, and are difficult to find an equalization point, therefore, if what existing kind disposably harvested
Words, the labour cost that yield will necessarily be decreased obviously, and save at this stage are much not enough to loss caused by making up the underproduction, then pass through
The remarkable benefit decline that Ji benefit can be harvested more manually, cannot achieve tender flower stalk entire mechanization operation from economic level.In addition, from
Disposable harvesting approach is much higher than traditional Multiple harvests mode for improving tender flower stalk production efficiency and vegetable plot utilization efficiency angle,
It is also to be of great significance for cost-saving synergistic particularly with the disposable harvest of realization for large-scale production.
In summary, it is necessary to solve existing tender flower stalk kind and disposably harvest asking of comparing that Multiple harvests yield is decreased obviously
Topic, and yet there are no the relevant technologies to solve the problems, such as this.
Summary of the invention
The present invention provides a kind of technological approaches in order to solve the above problem, has invented and a kind of has been suitble to disposable harvest operation

4, in above scheme, it is suitble to the biography of tender flower stalk germ plasm resource (JT-1) and Youlv 701 cabbage heart of disposable harvest operation
It unites the standards of Multiple harvests: when main colored a kind of sedge height is flushed with siphonal lobe, when overall bud is intended to out and does not open, often bursting forth with several small
Flower is commonly called as " neat mouth flower ", is Harvesting Date, harvests several times；Too early, flower a kind of sedge is excessively tender for harvesting, influences yield；Harvest too late, dish
A kind of sedge is excessively high, and fiber increases, and quality is then poor, yield decline.
There are two types of the standards disposably harvested for being suitble to the tender flower stalk germ plasm resource (JT-1) of disposable harvest operation: existing respectively
JT-1, Youlv 701 cabbage heart group in first single plant reach " neat mouth flower " standard same day and disposably all harvest JT-1.Oil
The standard of green 701 cabbage heart disposably harvested: first single plant reaches " neat mouth flower " the standard same day one in Youlv 701 cabbage heart group
Secondary property all harvests.
5, in above scheme, germplasm, which refers to, determines biological heredity character, and its hereditary information is transmitted to offspring's from parental generation
Inhereditary material is the entity of objective reality, and gene is known as on science of heredity.There is utility value in heredity, breeding and production
All living things material can be referred to as germ plasm resource, be to cultivate the substance base of new varieties from germ plasm resource for the angle of breeding
Plinth, the form of expression may is that local varieties, improve the breed, the kind of new breeding, introduced variety, seed, mutant, wild species,
Kindred plant, the various biotypes of artificial creation, vegetative propagation organ, individual cells, individual chromosome, individual gene, very

Design concept of the invention: Multiple harvests mode is compared in order to solve traditional disposable harvesting approach of tender flower stalk kind and is produced
The problem of amount significantly reduces, is readily apparent that and field single plant is allowed uniformly to reach harvesting standard, so that it may realize, in fact due to seed
Purity can not accomplish consistent completely with factors such as field subenvironments, be difficult to accomplish, it is understood that spending in the part single plant beginning latter
Secondary property harvesting yield necessarily declines, this is because evening receipts, which necessarily have plant part to bloom, excessively loses commodity.And only beginning
It disposably harvests before spending and single a kind of sedge quality is made to reach peak, disposable harvest is possible to maintain an equal level with the yield of Multiple harvests.
But the harvesting before beginning to spend of existing tender flower stalk kind does not reach maximum value due to single a kind of sedge quality, disposable crop also can it is obvious under
Drop, therefore, to find a kind of beginning Hua Qiandan a kind of sedge quality can reach the kind of maximum value, and be difficult to screen in current kind
It arrives.We are had found unintentionally and present inventive concept one when using turnip improvement tender flower stalk disease resistance trait in the offspring of backcrossing
The material of cause has carried out purposive improvement then, has obtained above-mentioned germplasm " JT-1 ", and the yield disposably harvested before spending that begins is high
In the yield of its own Multiple harvests, and it is significantly higher than the yield of traditional tender flower stalk kind " Youlv 701 cabbage heart ", and disposable
The tender flower stalk commodity of harvest is not more suitable for welcoming colored consumption area.In addition, genetic analysis shows that new traits can stablize something lost
It passes, illustrates to can use the donor of " JT-1 " as new traits gene, gather other merits, further increase yield and product
Matter establishes the tender flower stalk Breeds that different type is suitble to disposable harvest operation, meets the diversity requirement of production.
Characteristic of the invention is artificially to break subspecies estrangement, so that tender flower stalk and turnip gene are merged into each other, wound

Detailed description of the invention
Attached drawing 1 is the field tender flower stalk germ plasm resource " JT-1 " photo of the suitable disposable harvest operation of the embodiment of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments:
A kind of embodiment: method for creating for the tender flower stalk germ plasm resource being suitble to disposable harvest operation
In the following description, related parent material is that tender flower stalk kind " Youlv 701 cabbage heart " and turnip kind are " white
It is beautiful ".
Academy of Agricultural Sciences, Suzhou City (also known as Agricultural Science Inst. of Taihu District of Jiangsu Prov.) started a kind of be suitble in 2013
The initiative of the tender flower stalk germ plasm resource of disposable harvest operation, specific implementation step are as follows:
At the beginning of 1 month 2013 in greenhouse be broadcast live turnip kind " white jade turnip ", therefrom select the single plant of 5 plants of robust growths as
Female parent, greenhouse live streaming tender flower stalk kind " Youlv 701 cabbage heart ", therefrom selects the single plant of 5 plants of robust growths as father at the beginning of 2 months the same years
This, florescence hybridization, mixing harvesting obtains first-filial generation seed F1 after seed is mature.
First-filial generation seed F1 and tender flower stalk kind " Youlv 701 cabbage heart " is broadcast live in greenhouse in July, 2013, and the florescence respectively selects 5
Strain robust growth single plant is female parent with first-filial generation F1, and tender flower stalk kind " Youlv 701 cabbage heart " is male parent backcrossing, and seed single plant is adopted
Mixed in equal amounts obtains first backcross generation seed BC1F1 after receipts.
First backcross generation seed BC1F1 is broadcast live in greenhouse within 2 months 2014, more than 100 strain of final singling therefrom selects 10 plants of shapes and parent
This " Youlv 701 cabbage heart " single plant that appearance is similar and growing way is healthy and strong is selfed in florescence bagging, mixed in equal amounts after the harvesting of seed single plant
Obtain two generation seed BC1F2 of first backcross generation.
In July, 2014 therefrom selects 3 plants of bases in two generation seed BC1F2 of greenhouse live streaming first backcross generation, more than 300 strain of final singling
The elongation of portion internode distance is obviously earlier than traditional tender flower stalk kind and upright blade is compact, single plant of the glossy dark green growing way stalwartness of a kind of sedge color is in the florescence
Bagging selfing, seed single plant harvest the three generations's seed BC1F3 for obtaining first backcross generation respectively.
The three generations strain seed BC1F3 of 3 first backcross generations, more than 150 strain of final singling, each strain are broadcast live within 2 months 2015 in greenhouse
It selects the elongation of 3 plants of basal internodes distance obviously earlier than traditional tender flower stalk kind in system and upright blade is compact, the glossy dark green growing way of a kind of sedge color is strong
Strong single plant is selfed in florescence bagging, and seed single plant obtains four generation seed BC1F4 of 9 first backcross generations after harvesting respectively.
The four generation strain seed BC1F4 of 9 first backcross generations are broadcast live in July, 2015 respectively in greenhouse, distinguish more than 60 strain of final singling,
9 strain kind growing ways are neat, select that 5 plants of early flowering seasons are consistent, basal internode distance elongation is obviously earlier than traditional dish in each strain kind
A kind of sedge kind and upright blade is compact, single plant of the glossy dark green growing way stalwartness of a kind of sedge color is selfed in florescence bagging, seed single plant harvests obtain respectively
Obtain five generation seed BC1F5 of 9 first backcross generations.The same period is for newfound character, that is, basal internode distance elongation obviously earlier than biography
The character for tender flower stalk kind of uniting carries out genetic development research.
Five generation seed BC1F5 of 9 first backcross generations, respectively more than 60 strain of final singling are broadcast live within 2 months 2016 in greenhouse, the florescence covers net
The bee production of hybrid seeds is put, 9 strains are obtained.The strain for therefrom selecting 1 growing way, uniformity best is numbered " JT-1 " as research object.
Autumn in 2016 carries out field verification test:
2 kinds of test materials, i.e. strain kind " JT-1 " and tender flower stalk kind " Youlv 701 cabbage heart ".
2 kinds of harvesting approaches, i.e., disposable harvest and Multiple harvests, wherein the disposable harvest opportunity of " JT-1 " is divided to two again
Kind, reach " neat mouth flower " the harvest standard same day in " Youlv 701 cabbage heart " and " JT-1 " first single plant respectively, in both harvests
" JT-1 " is disposably harvested under opportunity.Multiple harvests are consistent with traditional water content in harvest.
5 test process are set altogether, and 30 square metres of plot area, 1000 plants of final singling, the random district's groups arrangement in field is repeated 3 times.
Test result shows that " JT-1 " is significantly higher than itself Multiple harvests after planting 40.5 days and the 43.5 days yield disposably harvested
Yield, the extremely significant yield less than itself Multiple harvests of the yield that " Youlv 701 cabbage heart " disposably harvests, and " JT-1 " is primary
Property harvest yield be all remarkably higher than the yield of " Youlv 701 cabbage heart " Multiple harvests, see Table 1 for details and table 2 for main experimental data.Separately
Outside, genetic analysis shows that new traits can stablize heredity, is controlled by cell nucleus gene, illustrates can use " JT-1 " as new
The donor of character gene gathers other merits, further increases yield and quality, establishes different type and is suitble to disposable receive
The tender flower stalk Breeds for obtaining operation, meet the diversity requirement of production.Conclusion: " JT-1 " is suitable as the dish of disposable harvest operation
A kind of sedge germ plasm resource.
" JT-1 " is different from traditional tender flower stalk kind, and the yield disposably harvested can be higher than the original of the yield of Multiple harvests
Because being: being shown in Table 1,40.5 days (when i.e. first single plant reaches " neat mouth flower " standard) after traditional category " Youlv 701 cabbage heart " is broadcast
The cell average product disposably harvested is 37.33 kilograms, and the cell average product 45.25 far below conventional multi harvest is public
Jin.This is because yield is mainly determined by single a kind of sedge quality and harvest item number, harvest item number is almost the same under this experimental condition, produces
The difference of amount is mainly determined by single a kind of sedge quality, that is to say, that the high yield of single a kind of sedge quality is also just high.2 are shown in Table, Youlv 701 dish
Single a kind of sedge quality that the heart disposably harvests cell is 40.8 grams, far below 47.3 grams of single a kind of sedge quality of conventional multi harvest cell, from
A kind of sedge slightly and long two data of a kind of sedge it is also seen that two ways harvest single a kind of sedge quality difference (forefathers research shows that single a kind of sedge quality and
A kind of sedge is thick and a kind of sedge length is positively correlated), a kind of sedge disposably harvested is slightly 1.55 centimetres and a length of 19.5 centimetres of a kind of sedge and is respectively less than Multiple harvests
Thick 1.71 centimetres and 21.4 centimetres of a kind of sedge, it is seen that a kind of sedges of traditional category Youlv 701 cabbage heart many single plants when disposably harvesting slightly and
A kind of sedge length fails to reach maximum value, then, single a kind of sedge quality is impossible to reach peak, and yield will be bright compared to Multiple harvests
Aobvious decline.And the yield 48.63 and 50.52 kilogram that " JT-1 " is disposably harvested is significantly higher than the yield of conventional multi harvest
44.12 kilograms of (see Table 1)s, the single a kind of sedge quality 49.9 and 51.5 gram disposably harvested are apparently higher than single a kind of sedge quality of Multiple harvests
44.5 grams of (see Table 2)s, it is opposite with traditional category performance.As can be seen from Table 2, processing 1 i.e. when JT-1 after broadcasting 40.5 days once
Property harvest when, plant height reaches 37.4 centimetres, a length of 22.7 centimetres of a kind of sedge of harvest, thick 1.75 centimetres of a kind of sedge, 49.9 grams of single a kind of sedge quality, place
For reason 2 i.e. when JT-1 disposable harvest at 43.5 days after broadcasting, plant height reaches 40.7 centimetres, and a length of 23.8 centimetres of a kind of sedge of harvest, a kind of sedge
Thick 1.86 centimetres, 51.5 grams of single a kind of sedge quality, processing 3 is i.e. when JT-1 Multiple harvests, and plant height reaches 44.1 centimetres, and a kind of sedge of harvest is long
Be 20.0 centimetres, thick 1.68 centimetres of a kind of sedge, 44.5 grams of single a kind of sedge quality, from 3 of above-mentioned JT-1 processing as can be seen that single a kind of sedge quality,
A kind of sedge is slightly and the rule that presents of the long size of a kind of sedge is that 2 > of processing handle 1 > and handle 3, and cell production is also presented identical rule, and plant height
Rule is presented and handles 2 > processing 1 for 3 > of processing.This and JT-1 are as breeding time, to increase edible a kind of sedge length more next for fiber backward
It is shorter, a kind of sedge slightly also just become smaller it is related, in this way handle 3 i.e. conventional multi harvesting approach list a kind of sedge quality be less than the primary of front instead
Property harvesting approach, reflect to being also in this way, the yield that " JT-1 " is disposably harvested is higher than its own Multiple harvests on cell production
Yield, to be apparently higher than the production disposably harvested different from universal law, that is, Multiple harvests yield of traditional tender flower stalk kind
Amount.It there occur a phenomenon in which that being primarily due to " JT-1 " same period plant height is apparently higher than traditional tender flower stalk kind, reaching " neat mouth flower "
" JT-1 " it is long can to harvest enough a kind of sedges in the past, guarantees that single a kind of sedge quality reaches peak before beginning to spend, and generates this phenomenon
Reason is because " JT-1 " is under normal cultivation condition again, and the elongation of basal internode distance is obviously earlier than oil about since 5 leaf phases
The tradition tender flower stalk kind such as green 701 cabbage heart, stem and leaf while fast-growth, bolting is normal, this character leads to " JT-1 " same period plant height
It is apparently higher than Youlv 701 cabbage heart equivalent type tradition tender flower stalk kind, i.e., 40.5 days " JT-1 " plant heights reach 37.4 centimetres after broadcasting
It is 7.2 centimetres higher than same period Youlv 701 cabbage heart plant height, and plant height when than Youlv 701 cabbage heart Multiple harvests is 3.1 centimetres high；
43.5 days plant heights reach 40.7 centimetres after " JT-1 " is broadcast, and plant height when than Youlv 701 cabbage heart Multiple harvests is 6.4 centimetres high,
And plant height when " JT-1 " Multiple harvests reaches 44.1 centimetres, plant height when than Youlv 701 cabbage heart Multiple harvests is 9.8 lis high
Rice.
From commodity, most of single a kind of sedge that " JT-1 " is disposably harvested will be significantly better than without little Hua, commodity
The tender flower stalk commodity of Multiple harvests, more suitable for not welcoming colored consumption area.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
