Abstract
The present invention relates to a production method of celery hybride seed. Said method uses xanthated celery parental material as female parent and uses celery parental material with normal green colour as male parent, and makes hybridization to produce the invented hybrid seed. Besides, said invention also provides its seedling stage purity detection method, its result is reliable, quick and accurate.
Description
Technical field
The present invention relates to production and the purity authentication method of a kind of vegetable crop crossbreed.
Background technology
Celery is at the cultivation history of the existing two thousand years of China, and all generally there is cultivation all parts of the country at present, is to be subjected to one of popular vegetable that China consumer likes deeply.The adaptability of celery is very wide, but join protection ground and almost annually cultivating supply of different ecological condition.Breeding lacks and systematically studies and utilize but China is to celery.Existing celery breeding work mainly is to utilize original landrace to purificate and rejuvenate or utilize the offspring of the hybridization of abiogenesis between the celery different cultivars to select, and breeds new kind, but these breeding researches and to utilize work be very limited.This and the status of celery in China's vegetables production and supply are extremely disproportionate.
The kind of using in China's celery production at present all is conventional varieties, and this celery mainly is that landrace are main, and celery mainly is the kind of introducing from external (based on the U.S.), as texts and pictures draw, Utah series etc.Domesticly also do not carry out heterotic research of celery and utilization, had a strong impact on China's celery and produced and its international competitiveness.Because the celery floral organ is little, the single fruit seed is few, is again the cross pollination vegetables, can't produce crossbreed with artificial emasculation pollination's method.Indivedual countries (Holland etc.) have the male sterile of utilizing to carry out few report that the celery hybrid produces in the world, but because celery male sterile genus anas male sterile type (GMS), to dial educated strain when producing hybrid in the field except that 50%, this is difficult in time dial up hill and dale remove in the actual production of hybrid seeds, can not guarantee the purity of celery hybrid.So at present domestic and international celery kind is still based on conventional variety.
Utilizing the male sterile line production first generation of hybrid is at present domestic and international unique celery hybrid production approach.But the selective breeding celery male sterile line cycle is long, and technology is numerous and diverse, but also exist above-mentioned be difficult in time dialling up hill and dale remove 50% and can educate strain and make problems such as hybrid purity can not guarantee.Utilize the celery hybrid of male sterile line production also can't just carry out the evaluation of purity simultaneously in seedling stage.
Summary of the invention
(1), the technical problem that will solve
The purpose of this invention is to provide and a kind ofly can set up a kind of new celery hybrid production method by the present invention, set up simultaneously fast, accurately, good reproducibility, the impurity-removing method in seedling stage that celery hybrid purity authenticate technology that technology is simple to operation and field produce.
(2), technical scheme
The present invention uses yellow celery parent material to be female parent, and normal green celery parent material is that male parent is hybridized the production crossbreed.
Yellow celery parent material of the present invention is the celery material of yellow sudden change or forms through the hybridization backcross transformation that its cotyledon and true leaf are yellow.
The present invention when hybridization father and mother this plant by 1: 3～4 ratios, from the female parent that has the yellow proterties hybrid seed of gathering.
The purity authentication method of a kind of celery hybrid of the present invention utilizes the yellow character pair crossbreed of celery cotyledon and true leaf to carry out purity and identifies, launches or seedling carries out purity when 2-3 sheet true leaf occurring and identifies at cotyledon.
Concrete seed selection process is as follows:
Occur 2 strain yellow mutant strains among " 9816 celery " inbred line self progeny, select yellow strain selfing, obtain the 9816 individual plants system of whole yellows, selfing obtains " yellow 9816 celeries " again, with it is female parent, draws 9701 to be paternal hybrid with the normal celery inbred line of green texts and pictures, F
1All be normal green strain, F
1Selfing separates the normal green strain of acquisition again: the yellow strain is 3: 1, selects yellow strain wherein to make female parent, draws 9701 to backcross with texts and pictures, F
1All be normal green strain, backcross progeny selfing (BC
1F
2) separate obtaining normal green strain: the yellow strain is 3: 1, selects wherein yellow to involve 3 generations of continuous individual plant selfing in a criminal case and obtains yellow 9701 inbred lines.Except that yellow, other proterties of yellow 9701 are near " texts and pictures draw 9701 ".
(3), beneficial effect
The celery kind first generation of hybrid that is applied as of the technology of the present invention melts the new approach of having warded off, yellow character inheritance among the present invention is stable, its performance is not subjected to the influence (light green color proterties affected by environment has difference significantly in this and the celery) of weather, cultivation condition etc., make pseudostationary stably from hybrid population, differentiate, the hybrid purity qualification result is reliable, quick, accurate, make the purity assay period shorten 3 months, the purity appraisal cost has reduced by 90%; The present invention also can promptly dial pseudostationary in seedling stage in the production, reduce the economic loss that causes because of hybrid purity, so can make the celery seed industry obtain huge economic benefit and social benefit except that yellow.
Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Utilize " yellow 9816 inbred lines " and " yellow 9701 inbred lines " the spring in 2004,30 hybrid combinations have been prepared with leaf look normal 15 parts of green celery inbred lines respectively, carried out varietal yield test autumn and winter in 2004 in the greenhouse, therefrom filter out 4 good hybrid combinations, further produce the experiment well afoot.
