Description
One, technical field
The cultivation and the application in the complete female hua ' nan-type cucumber of the present invention south China complete female 09 belong to the biotechnology breeding field, are exclusively used in to cultivate the allfemale type new breeds of cucumbers.
Two, background technology
Cucumber is one of main vegetable crop of global common cultivated, and its area under cultivation ranks first in China protection ground vegetables, has a very important role to guaranteeing China vegetables anniversary stable market supply aspect.
Cucumber is the therophytes of the different flower of monoecism.In the seedling phase bud just taking place, and carries out the sexual type differentiation of bud.Flower is generally unisexual flower, but have except that female flower, male flower, also have perfect flower.Its plant sexual type has: pure female plant, monoecism, pure staminiferous plant,, pure complete stool, andromonoecy, the full homophyletic of male and female.Wherein with pure female plant and monoecism be the master (JackE.Staub, Matthew D.Robbins, Todd C.Wehner.Vegetables I.Handbook of PlantBreeding. [M] .Springer New York, 2008:250).With regard to kind or strain system, pure female plant system, pure strong female plant system, female series, female complete stool system, male complete stool system, strain system, pure male and female plant system, pure staminiferous plant system etc. are fully arranged roughly. wherein female series and male and female plant are to be widely used.(Zhang Chunping, what is flat, Qu Zhicai, etc. silver nitrate is to the male effect of luring of cucumber female series. Southwestern University's journal (natural science edition), 2007,29 (2): 49～52).
The sexual type of cucumber is the key factor that influences its output, and the allfemale type cucumber is meant that plant only opens female flower and do not open the strain of male flower, often shows advantages such as precocity, melon are close, high yield.In addition, utilize allfemale type cucumber system half-blood to need not to castrate, practiced thrift the labour, reduced breeding cost, made half-blooded purity is very high.The half-blood that does maternal preparation with the allfemale type cucumber also multilist existing precocious, female flower is many, adopt advantage such as concentrated, high yield of melon phase.Therefore the seed selection of allfemale type cucumber just becomes important research contents in the breed cucumber with application.But the allfemale type kind of present domestic cucumber mainly is the European greenhouse type cucumber from external introduction, and the ecotype is comparatively single, can not satisfy the needs of production and breeding.
This seminar early-stage Study finds, the gynoecy shape of cucumber is mainly by a pair of nuclear gene control, complete female to weak female be dominance.When the gynoecy site was in homozygotic state, the performance of gynoecy shape was stable, is not vulnerable to Effect of Environmental such as light temperature.And when the gynoecy site is in heterozygous state; The performance of its gynoecy shape and genetic background have certain relation; The stable gynoecy of performance during part ecotype heterozygosis, and the part ecotype is subject to Effect of Environmental such as light temperature in addition, the incomplete dominance characteristic occurs; A spot of male flower occurs at the plant base portion, but overall female performance is all very strong.(Lou Qunfeng; The cloning and expression research [M] of cucumber gynoecy gene molecule marker and acc synthase gene. 2004 doctorate papers) so; Through hybridize with the female series cucumber, backcross, the mode of selfing, be cucumber to the transformation of gynoecy gene to non-gynoecy in the middle of, be to cultivate female stable new breeds of cucumbers; Widen the ecotype of allfemale type cucumber, improve the favourable approach of the availability of allfemale type cucumber.
