Abstract
The invention discloses a method for producing edible sunflower hybrid seeds. The method comprises the following steps of: (1) culturing parents a, namely planting an edible sunflower variety a which has high combining ability and good economic characteristic in a production site; and through 5 to 8 generations of sister hybridization, selecting strains which have strong adaptability and high purity without degeneration after the sister hybridization as the parents a; (2) culturing parents b, namely planting an edible sunflower variety b which has the same flowering phase, maturation phase and strain height as those of the parents a, and has disease resistance and seed size complementary for those of the parents a; and after 5 to 8 generations of self-copulation, selecting the strains which have the high combining ability as the parents b; and (3) producing hybrid seeds, namely planting the parents a and the parents b at the same time; and mutually pollinating the parents a and the parents b in the flowering phase in order to culture the hybrid seeds. The method for producing the edible sunflower hybrid seeds has the characteristics of simple processes, low cost, randomly selected hybrid combination and strong combination advantages. The hybrid seeds have the advantages of disease resistance, high yield, good quality, strong growth potential and the like.
Description
Technical field
The present invention relates to the producing method for seed of a kind of edible sunflower crossbreed.
Background technology
Current edible sunflower cross breeding seed generally adopts the method (male sterile line, maintenance line, recovery system) of three series mating, be first seed selection male sterile line, maintenance line, recovery system, be to press different proportion (4: 2 with male sterile line with recovering then, 3: 1 etc.) plant in the land for growing field crops, the adjusting florescence makes its unanimity, finish this hybridization of father and mother by insect pollination or artificial pollination mode, cultivate and obtain crossbreed.The production of hybrid seeds program of three line method and production link more complicated, so that the cycle of the new combination of seed selection is long, efficient is low, difficulty is big, combination advantage link not strong, that promote is many, speed is slow, the cost height that causes seed. price is expensive, these all are one of factors of being restricted on cultivated area of sunflower Three-line Hybrid kind, also are that China's edible sunflower can not be taken out one of reason of advantage hybrid combination as early as possible.
In the prior art, the another kind of method of edible sunflower cross breeding seed is to utilize sunflower caryogram male sterile line to carry out the two line method production of hybrid seeds, be field planting caryogram male sterile line and recovery system, pull out the educated strain in the male sterile line before blooming, finish this hybridization of father and mother by insect pollination or artificial pollination mode, cultivate and obtain crossbreed.Sterile line propagation complexity, low, the cross breeding seed cost height of efficient.
The method production of hybrid seeds of research by chemical emasculation is arranged, promptly utilize chemicals to induce the maternal sterility that produces, finish this hybridization of father and mother, cultivate and obtain crossbreed by insect pollination or artificial pollination mode.Chemical emasculation is subject to environmental influence effect instability, the breeding cost height, and can cause environmental pollution.
Consider from the long-range strategy of the crop hybrid advantage production of hybrid seeds, should explore new technology path, simple and easy in the hope of adopting, method replaces three line method fast and efficiently.
Summary of the invention
In order to solve existing the problems referred to above in the prior art.According to the self-incompatible biological property of edible sunflower, the invention provides the producing method for seed of a kind of edible sunflower crossbreed.
The producing method for seed of edible sunflower crossbreed provided by the invention comprises the steps:
(1) cultivate parent a: at grown place plantation coordinate force height, edible sunflower kind a that economic characters are good, the sisters by 5-8 generation hand over, and select that wherein adaptability is strong, purity is high, sisters hand over the strain system that does not degenerate, as parent a;
(2) cultivate parent b: at grown place plantation florescence, maturing stage and plant height and described parent a quite and the edible sunflower kind b of disease resistance and seed size and described parent a complementation, selfing 5-8 is after generation continuously, and the strain that selection coordinate force is high is, as parent b;
(3) cross breeding seed: plant above-mentioned parent a and parent b simultaneously, above-mentioned parent a and parent b pollinate mutually in flowering stage, cultivate crossbreed a*b and crossbreed b*a.
As preferably, above-mentioned steps (3) cross breeding seed process is: above-mentioned parent a and parent b plant the zones of different in the grown place simultaneously, gather the pollen of above-mentioned parent a and parent b respectively to adopt the powder instrument, parent b to WUHUAFEN pollinates with the pollen of above-mentioned parent a, cultivation obtains crossbreed b*a, parent a to WUHUAFEN pollinates with the pollen of above-mentioned parent b, cultivates to obtain crossbreed a*b, and remaining pollen is used as beauty treatment and health products.
Be further used as preferably, the above-mentioned powder instrument of adopting is the dust catcher that front end installs the wire protection network additional.
As preferably, another process of the described cross breeding seed of above-mentioned steps (3) is: above-mentioned parent a is alternate with interlacing with above-mentioned parent b, mode is planted one to one, flowering stage, with the floral disc corresponding contact of the floral disc of above-mentioned parent a plant with corresponding in the ranks parent b plant, make and pollinate mutually between floral disc, cultivate and obtain crossbreed a*b and crossbreed b*a.
Be further used as preferably, above-mentioned parent a is 1: 1 with the capable ratio of parent b, and line-spacing is 70cm, and spacing in the rows is 40cm.
The producing method for seed of edible sunflower crossbreed provided by the invention can reach following technique effect:
1, parental combination can choose at random as required, and combination advantage is strong.
2, seed selection time weak point, production of hybrid seeds process is simple, and breeding cost is low, high efficiency.
3, can obtain three products that economic worth is arranged after the production of hybrid seeds.
4, crossbreed a*b and crossbreed b*a have disease-resistant, high yield, high-quality, advantage such as growth potential is strong.
5, but the dust catcher that installs the wire protection network additional with front end prevents injury and the suction of dust catcher to gynoecium simultaneously as sampling instrument scale collecting pollen.
6, parent a and parent b, plant more alternate than interlacing with 1: 1 row one to one mode plant, line-spacing is 70cm, spacing in the rows is 40cm, makes floral disc contact pollination carry out easily, can avoid parent's sisters to hand over simultaneously.
