Description
Technical field
The present invention relates to the breeding method of a kind of cotton variety, cultivate high-quality, the method for high ginning outturn Upland Cotton particularly to a kind of.
Background technology
The Cotton Gossypii type of China's plantation mainly has Gossypium hirsutum L. and sea island cotton, and wherein Gossypium hirsutum L. cultivated area is maximum, and sea island cotton is only planted in part cotton region, Xinjiang.Sea island cotton quality better, but yield poorly, therefore select high-quality Upland Cotton to become breeding man focus of attention.
High-quality Gossypium hirsutum L., also known as Midlle-longstaple cotton, refers to more than fibre length 30mm, more than specific strength 33cN/tex, micron value 3.8～4.5, can the raw cotton of the medium and high-grade goods such as 60 combed yarns of spinning yarn 40-, belong to one grade of Cotton Gossypii that in high quality cotton category, class is higher.
Ginning outturn is one of output of cotton three basic elements.General ginning outturn is high, and yield is the highest, and both are proportionate, and heavy without significant correlation with bell number and bell, therefore improves ginning outturn and will not produce negative interaction in the balance of yield factors on coordinating.Therefore SOYBEAN IN HIGH-YIELD BREEDING must focus on the raising of ginning outturn.The U.S. Bridge and Meredith1978, within 1979, carry out planting with current kind by out-of-date kind compare after think, the increase of lint yield, mainly ginning outturn are worked.
The eighties in 20th century, the developed countries and regions such as Europe, the U.S., Japan have started the renewal of cotton textiles industry equipment, spinning of being splited by part ring changes into without splitting open-end spinning, production efficiency is made to improve 3 times, cost declines 1/3, product specification increases substantially, and compared with ring spun yarn, the feature of open-end yarn is fibre strength and the fineness impact maximum on yarn and goods thereof.High-quality cotton fiber quality length is coordinated the most by force, can be weaved high by spinning process and spin and grade textiles, be the high-grade raw cotton of Modern Textile Industry urgent need, be also the key improving textile domestic and international market competitiveness.
China's high-quality Upland Cotton research starts from the eighties in 20th century, Zhang Fengxin etc. (1999) use sea-land hybridization, create ' 9208007 ", " 9217027 " two serial high-quality cotton breeding materials, be bred as the cotton varieties such as high-quality Gossypium hirsutum L. " Chongqing cotton No. 1 ".Ke Teng company of Jiangsu Province on this basis, has been bred as the high-quality cotton varieties such as " cotton No. 1 of section ", " Kemian 3 ", " cotton No. 5 of section ".Excellent with fiber quality of raising variety, but it is not strong to there is disease resistance, the defect (38-39%) that ginning outturn is on the low side, applies poor effect on large area produces.
This COMPARISON OF CHARACTERS of ginning outturn is stable, is decided by breediness to a greater extent.Blindly pursue high ginning outturn or think ginning outturn unimportant be all unilateral.In general, high ginning outturn kind often floss length is shorter, and son refers to relatively low, and infertile sub-rate is high, but these contradictions not can not be unified.The negative relation only balanced and break between fiber yield and economic characters, just can cultivate high-quality, high ginning outturn cotton new varieties (being).
It is one of effective way improving yield, improving quality, increase resistance that cotton hybrid vigor utilizes.Research both domestic and external shows, the amount of increase in production of Cotton Gossypii hybrid is generally 5-35%.But, Cotton Gossypii is the often cross-pollinated crop of allotetraploid, and genetic background is complicated；Being again indefinite inflorescence, the florescence is long, and flower disperses；Therefore the difficulty application such as concentration more diplontic than Oryza sativa L. and Semen Maydis etc. of Study on Heterosis and utilization is much bigger.
Summary of the invention
For solving the rich anti-excellent combination of cotton variety, the technical barrier that fiber quality length has both the most by force, propose a kind of to cultivate high-quality, the method for high ginning outturn Upland Cotton.The present invention is achieved by the steps of:
1) select high yield, high ginning outturn, Resistant Upland Cotton (being) as maternal, select high-quality Upland Cotton (being) as male parent, and using high-quality Upland Cotton (being) as recurrent parent；
2) parents carry out group gas-mixing hybridization by artificial supplementary pollination, the F that selection traits is stable1In generation, carry out reestablishing diplomatic relations obtaining allometrosis with high-quality recurrent parent；
3) allometrosis obtains F through selfing2Generation；
4) F2In generation, obtains F after continuous Single-plant selection3-F4Generation；
5) F3To F4In generation, carry out early generation selection and individual plant quality, ginning outturn orientation mensuration, and carry out south numerous added-generation；
6) to F5To F8In generation, carries out mixing and selects and plant ginning outturn, quality and resistance Comprehensive Evaluation, identify that final election ginning outturn is more than 40% in conjunction with south numerous added-generation, multiple spot, high-quality Upland Cotton more than fibre length 30mm, more than specific strength 33cN/tex, between micron value 3.8～4.5.
Step 5,6) described in generation morning select, the orientation of fiber quality and ginning outturn measures and combines, and with ginning outturn, quality is selected the overall process through Fruit variety；During cultivating, have employed south numerous added-generation, multiple spot qualification etc., increase space-time selection pressure and the method carrying out Single-plant selection and purification.
