Abstract
The invention discloses a production method of an environment-friendly economic cotton hybrid. As the production method adopts a special parent, the hybrid can be subjected to forge identification indoors during a main leaf period, so that the rapidness and the accuracy of the identification are improved, the purity of seeds is guaranteed, the stability of a seed market is ensured, the seed quality is guaranteed, and the phenomenon of forging and faking is effectively attacked. The production method can greatly reduce acid content during a process of removing woolen by sulfuric acid before sowing, reduce the damage to the seeds by the acid, guarantee the integrity of the seeds and protect environment, is beneficial to the growth of the seeds, is simple and practical, can be used for identifying the purity of the hybrid well for multiple times, avoids the phenomenon of forging and faking well, and protects the benefits of cotton planters.
Description
Technical field
The invention belongs to cotton planting field, relate in particular to a kind of method of producing environmental protection and economy type cotton hybrid kind.
Background technology
High yield improved seeds are volume increase bases of crop, each crop large area volume increase is all the result of good replacement kind spread, cultivating good replacement kind is the direction that each large agricultural country of the world endeavours research all the time, and it is exactly a good example that hybrid cotton is promoted.But in promoting for improved seeds, existing problems are paid attention to not, usually causing grower to underestimate mistakenly the yield potential of improved seeds, and make improved seeds promote delay in time, even hesitate to move forward.For crossbreed, in production, purity of hybrid height and yield potential size are mutually to echo, and good Hybrid purity declines, and the performance that extremely affects kind yield potential even causes the underproduction.Cotton hybrid production of hybrid seeds majority is artificial emasculation pollination, and whether thoroughly artificial emasculation directly affects the quality of seed, and artificial emasculation not thoroughly or leak and spent the maternal selfing Cheng Ling that hero causes, is a major reason of impact hybridization cotton seed purity; More have or not good production of hybrid seeds family to pay seed inferior.And for cotton seed purity Morphological Identification, be almost that naked eyes can not be distinguished, for the strain Purity of cotton seed, mend the fold after the sheep is lost often late, do not reach the set goal.
Summary of the invention
Object of the present invention provides a kind of method of producing environmental protection and economy type cotton hybrid kind, is intended to solve the existing Purity to cotton seed, the problem falling flat.
The object of the present invention is to provide a kind of method of producing environmental protection and economy type cotton hybrid kind, said method comprising the steps of:
Non-transgenic light seed female parent is cultivated to screening, and the light seed female parent of high-combining ability is cultivated in screening;
Choose high-combining ability transgenic pest-resistant material and do male parent, with high-purity light seed hybridization of female parent, obtain transformation transgenic pest-resistant crossbreed;
Crossbreed for high yield carries out Purity.
Further, described female parent is cultivated to screening, guarantees that maternal high-purity method is:
Seed selection non-transgenic light unginned cotton flower parent is maternal, after cotton ginning, directly the hair seed mixing can be rejected.In field planting management process, use kanamycin evaluation and screening seedling stage, transgenosis hybrid strain is pulled out, guarantee maternal purity.
Further, described in choose male parent, with high-purity hybridization of female parent, the method for obtaining crossbreed is:
Seed selection high-combining ability transgene cotton is made male parent, hybridizes assembly with light seed female parent, obtains a collection of transgenosis photon cotton crossbreed F
1; By randomized block experiment design cotton crossbreed F that plantation is joined
1according to People's Republic of China's agricultural industry criteria (NY/T1302-2007) < < variety of crops experimental technique rules-cotton > >, require to test, therefrom select high yield, high-quality and how anti-F
1strong advantage combination.
Further, the described crossbreed for high yield carries out Purity method and is;
The F of the first step to results
1seed carries out Morphological Identification, rejects Westerner and retains light seeds, with the seed that guarantees that the seed of results is on female parent to be tied; Second step is to above-mentioned smooth seed F
1sample seed sprays or smears kanamycin at indoor culture to leaf period, identifies non-transgenic male parent pollination ratio in sample; By secondary, identify, crossbreed F guarantees to be up to the standards
1it is highly purified seed.
Further, described method adopts special parent to carry out Purity to crossbreed, identifies the crossbreed maternal fraud of adulterating.
Further, before described method has greatly reduced sowing, sulfuric acid lint process is measured with acid, has protected environment.
The present invention is a kind of method of production environmental protection and economy type cotton hybrid kind, the method is utilized special parent, improve the accuracy to Hybrid seed purity test, in indoor seedling stage, can whether add female parent to crossbreed and make evaluation, well stopped fake and forged phenomenon; Protected environment, before sowing, sulfuric acid lint process greatly reduces by acid amount, has alleviated the pollution to environment such as sulfuric acid lint process and salt acid vapour, the concentrated sulfuric acid, dilute sulfuric acid, foamed acid; Cost-saving; Reduced seed mechanical damage, the growing way of emerging is good, and seed water suction is fast,, be beneficial to and early send out strong sprout; Improved seed disease resistance.
