Description
Technical field
The invention belongs to agricultural technology field, specifically, it is related to a kind of selection without branch rape new material.
Background technology
The rapeseed plants that China cultivates at present are higher, and general plant height is in 170-200cm, and once effective branch amount 8-12 is individual,
25-30 days florescence, individual plant silique number 250-400, mass of 1000 kernel 3.2-3.8g, easily lodging, the maturity period is inconsistent, is unfavorable for
Mechanization sowing and harvest.
The content of the invention
It is an object of the invention to provide a kind of selection without branch rape new material, this method seed selection without branch
Rape, does not have a branch when ripe, only main inflorescence is bloomed and tied silique, and plant is short and small, general plant height 80-100cm, florescence 7-
10 days, individual plant silique number 40 or so, mass of 1000 kernel 3.8-5.9g, planting density was difficult lodging, profit up to more than 100,000 plants/acre
In Mechanization sowing and harvest.
Its concrete technical scheme is：
A kind of selection without branch new rape variety, comprises the following steps：Double 11 do female parent during First Year is used, and recover
It is that 506C does paternal hybrid, Second Year to the continuous generation of selfing four in the 5th year year, discovery in the 5th year has totally 399 plants of two pedigrees, just
Normal 342 plants of rape, few 43 plants of branch rape, no 14 plants of branch rape carries out selfing to few branch and without branch rape then, the
Have within 7 years one whether there is the part of branch rape new material more than 200 without branch new material selfing homozygosis to autumn sowing in the 7th year, also simultaneously
It is found that no 10 plants of branch rape sterile plant.
Step 1, in double 11 do woody, 506C does paternal hybrid；
In step 2, the Second Year continuous generation of selfing four by the 5th year, analyzed through lab-quality, selection content of erucic acid 1% with
Under, sulphur resources are in 30 μm of below ol/g individual plant planted in fall, and a class is pushed into the 5th year；
Step 3, discovery in the 5th year have totally 399 plants of two pedigrees, normal 342 plants of rape, few 43 plants of branch rape, no branch
14 plants of rape, carries out selfing to few branch and without branch rape then；
Step 4, there is within the 7th year one without branch new material selfing homozygosis, branch rape new material has been whether there is to autumn sowing in this year
More than 200 parts, no 10 plants of branch rape sterile plant.
Without branch rape completed in Xibei Univ. of Agricultural ＆ Forest Science ＆ Technology's Xixiang rape base, at that time purpose be in double 11 come
The 506C restorers of our seed selections are improved, anti-sclerotiniose and lodging resistance is improved.The two parents do not send out through selfing for many years to homozygosis
It is existing without branch rape.By biparent cross, no branch rape new material is generated in self progeny, but the two parents exist
When other materials hybridizes, also find no no branch rape and show.Double 11 hybridize again with 506C restorers in, in selfing
No branch rape can also be repeated in offspring, this explanation has a parent to contain the recessive base for whetheing there is branch rape in parents
Cause, concrete reason we organized the relevant personnel carry out association area research.
Without branch rape plant height 80-100cm, 7-10 days florescence, individual plant silique number 40 or so, per seed number per pod 20~25
Grain, mass of 1000 kernel 3.8-5.9g, content of erucic acid 0.19~0.58%, 19.39~25.67 μm of ol/g of sulphur resources, oil content 45~
54%.
Compared with prior art, beneficial effects of the present invention：
The present invention method seed selection without branch rape, there is no branch, only main inflorescence knot silique when ripe, plant is short,
General plant height 80-100cm, 7-10 days florescence, individual plant silique number 40 or so, mass of 1000 kernel 3.8-5.9g, planting density is reachable
More than 100000 plants/acre, lodging is difficult, planting density shortens more than 20 days than ordinary cole up to ten thousand plants/acre of 10-15, florescence, received
Obtain the phase shorten 7-10 days, can broadcast sowing and mechanical planting, per mu yield estimation can reach more than 250kg, be conducive to Mechanization sowing with
Harvest.
Brief description of the drawings
Fig. 1 is the flow chart of the selection of the invention without branch rape new material.
Embodiment
Technical scheme is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
On May 15th, 2014, silique is recorded in Shaanxi Province Xixiang County jujube garden village Xibei Univ. of Agricultural ＆ Forest Science ＆ Technology's rape experimental plot
When character and investigation disease, a kind of Wild cabbage type is found that in the selfing based material that numbering is 969-974 without branch rape, altogether
It was found that there is 14 plants.Selfing is produced material source in double 11/506C filial generations in being, wherein female parent Zhong Shuan11Xi Chinese agricultures section
The double low normal rapeseed new varieties of the Wild cabbage type of oil crops research institute of institute seed selection, are the homozygous line of our selfings, its erucic acid contains
Amount 0.0%, 23.49 μm of ol/g of grouts glucosinolate content, oil content 47.52%. male parents 506C is that the Wild cabbage type of our seed selections is double low
Normal rapeseed new lines, are also a cold-resistant, drought-enduring type restorer.Its content of erucic acid 0.29%, the μ of grouts glucosinolate content 21.37
Mol/g, oil content 48.12%.But in selfing for many years, the two parents were never had found without branch rape new material.
Double 11 do female parent in reference picture use in 1,2010, and restorer 506C does paternal hybrid, the continuous selfings of 2011-2014
In four generations, find within 2014 there are totally 399 plants of two pedigrees, normal 342 plants of rape, few 43 plants of branch rape, no 14 plants of branch rape,
Selfing is carried out to few branch and without branch rape then, has within 2016 one without branch new material selfing homozygosis, to the autumn in 2016
Broadcast and whether there is the part of branch rape new material more than 200, no 10 plants of branch rape sterile plant.
(1) double 11 do female parent in using, and restorer 506C does paternal hybrid, can repeat no branch oil in self progeny
Dish new material.In the parents for illustrating no branch rape, there is a parent to contain the recessive gene for whetheing there is branch rape；(2) branch oil
Dish new material has heredity, is found from the generation of selfing 4 without branch rape new material, to the 7th generation without branch rape homozygosis, explanation
With heredity, available for seed selection without branch new rape variety.(3) be bred as without branch rape plant height 84cm, individual plant silique 40
It is individual or so, mass of 1000 kernel 4.9g.Content of erucic acid 0.24%, 18.21 μm of ol/g of sulphur resources, oil content reaches 50.23%.It is current
One of cabbage type rape has the new germ plasm of innovative value；(4) rape is short and small without branch rapeseed plants, and mass of 1000 kernel is big, oil-containing
Amount is high, and planting density is difficult lodging up to more than 100,000 plants/acre, and the florescence shortens more than 20 days than ordinary cole, harvest time contracting
It is short 7-10 days, it can broadcast sowing and mechanical planting, can also postpone sowing, per mu yield, which is calculated, can reach more than 250kg, and maturity period tool is consistent
Property, be conducive to Mechanization sowing and harvest.
The foregoing is only a preferred embodiment of the present invention, protection scope of the present invention not limited to this, any ripe
Those skilled in the art are known in the technical scope of present disclosure, the letter for the technical scheme that can be become apparent to
Altered or equivalence replacement are each fallen within protection scope of the present invention.
