Abstract
The invention discloses a kind of cotton three series cross breeding process, including base selection, Juvenile stage principle, isolation, implantation methods, pollination, cultivation management, removal of impurities pure keeping, harvest, Seed inspection.By means of the present invention, without using the traditional artificial auxiliary production of hybrid seeds, breeding cost is substantially reduced；And merely with the ingenious arrangement in parent field, spiraled in conjunction with small aircraft low-latitude flying to produce " three systems " cenospecies, to solve hybrid cotton F1For the excessively high problem of seed price, realize that hybrid cotton industry continues healthy and stable development.
Description
Technical field
The present invention relates to a kind of high efficiency, low cost cotton three series cross breeding process, belong to cotton breeding technical field.
Background technique
China hybrid cotton cultivated area maintains more than 1,000 ten thousand mu in recent years, accounts for the cotton gross area is planted in the whole nation 1/5, and with kind
It is leading for planting the cenospecies of artificial emasculation hybridization production.However as the reduction of rural laborer, traditional artificial emasculation hybridization system
Kind mode has been unable to meet the demand of hybrid cotton industrialization, has started to restrict hybrid cotton F1In generation, promotes and application.Cotton three series method
It is that hybrid seed is produced using " sterile line ", " keep system ", " restorer ", it is not only at low cost, speed is fast, and simple and effective,
It is one of the approach for overcoming the problems, such as that traditional artificial emasculation hybrid seeding recruitment is maximally efficient.
Currently, cotton " three systems " production of hybrid seeds is to produce cenospecies using insect supple-mentary pollination, although reducing hybrid cotton recruitment
Cost, but there is also the risks such as string powder.Therefore, it is the interests for ensureing numerous cotton growers, prevents hybrid F1Abortion keeps hybrid F1
Consistency and hybrid vigour repeatability, it is necessary to develop a kind of new cotton three series cross breeding process.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of high efficiency, low cost cotton three series are miscellaneous
Hand over kind of a preparation method.
To achieve the above object, the technical solution adopted by the present invention: a kind of cotton three series cross breeding process, including such as
Lower step:
(1) base selection: should select to be isolated with favourable conditions, convenient for management, topography is flat, irrigation and drainage are convenient, the medium above fertility and
Nothing or light wilt disease, the cotton field without quarantine pest and disease damage, as seed farm；
(2) Juvenile stage principle: sterile line, restorer seed should select original seed, and original seed refers to the of breeder's seminal propagation
A generation is to the third generation or by the seed for reaching original seed quality standard of seed production technical regulation production；
(3) be isolated: seed farm should have round isolated area of the 2500m or more as radius, isolated area plantation when being isolated using space
Restorer；
(4) implantation methods: being sowed using method for culturing and transplanting seedlings, determines sowing day according to the maturity of Parent and growth and development characteristics
Phase, male parent are restorer, and female parent is sterile line, and male parent entered flowering stage than maternal 5-7 days in advance；Parent plant division interval
Plantation is arranged in " product " font, to guarantee that female parent comes into full contact with male parent, surrounding setting protection row (protection line width 3-5m),
Protection row plantation male parent material；
(5) pollinate: full-bloom stage seed farm is to fly in 0.5-1m from cotton plant overhead height in cotton plant overhead using small aircraft
Spiral supple-mentary pollination；
(6) it cultivation management: conventionally carries out；
(7) clean pure keeping: pulling out the different cause of growing way appearance in time, grows these obvious irregular abnormal sterile lines, is extensive
It is again plant；
(8) harvest: should first be harvested when harvest and pull out restorer, then receive female parent, when preventing harvest male parent it is miscellaneous enter female parent；
(9) Seed inspection Seed inspection: is carried out according to GB/T 3543-1995.
Compared with prior art, the present invention have the utility model has the advantages that
1, by means of the present invention, without using the traditional artificial auxiliary production of hybrid seeds, breeding cost is substantially reduced；
2, it merely with the ingenious arrangement in parent field, spirals in conjunction with small aircraft low-latitude flying to produce " three systems " cenospecies, with
Solve hybrid cotton F1 For the excessively high problem of seed price, realize that hybrid cotton industry continues healthy and stable development.
Detailed description of the invention
Fig. 1 is father of the present invention, female parent and protection row arrangement schematic diagram.
Specific embodiment
Presently in connection with specific embodiments and drawings, next the invention will be further elaborated.
Embodiment one
The high efficiency, low cost cotton three series cross breeding process of the present embodiment, includes the following steps:
(1) base selection: it should select to be isolated that with favourable conditions, convenient for management, topography is flat, irrigation and drainage are convenient, the medium above fertility, nothing
Or light withered (Huang) withers disease, the cotton field without quarantine pest and disease damage, as seed farm；
(2) Juvenile stage principle: sterile line, restorer seed should select original seed, and sterile line, restorer florescence are consistent, specifically,
Female parent selection sterile line, male parent select restorer；
(3) be isolated: seed farm should have round isolated area of the 2500m or more as radius when being isolated using space, and isolated area can plant
Plant restorer；
(4) implantation methods: preferably using method for culturing and transplanting seedlings to sow, and determines sowing according to the maturity of Parent and growth and development characteristics
Date, male parent (restorer) shift to an earlier date 5-7 days than maternal (sterile line) and enter flowering stage；Parent plant division interval plantation, in " product "
Font arrangement, as shown in Figure 1, to guarantee that female parent comes into full contact with male parent, surrounding setting protection row protects row plantation male parent material
Material；Flowering and boll-setting period checks fertility by strain, is listed or ties up knitting wool label at the top of sterile plant stem；
(5) pollinate: full-bloom stage seed farm using small aircraft, spiral supple-mentary pollination in outage 0.5-1m on cotton plant by flight；
(6) it cultivation management: is executed referring to NY/T 1292-2007；
(7) clean pure keeping: pulling out abnormal sterile line, restorer plant in time；Abnormal strain refer to growing way appearance obviously and its
He is inconsistent, the irregular plant of growth；
(8) harvest: should first be harvested when harvest and pull out restorer, then receive female parent, when preventing harvest male parent it is miscellaneous enter female parent；
(9) Seed inspection Seed inspection: is carried out according to GB/T 3543-1995.
Table one is demonstration result of the invention
The result shows that: when planting density is 1400 plants/acre (700 plants/acre of male parent density;700 plants/acre of maternal density), seeding row spacing
When being 48cm × 100cm, maximum hybrid seed yield can get.
