Abstract
The invention relates to a method for cultivating a new high-yield soybean variety, which comprises a crossing parent selecting method and a castration method in hybridization. The hybridization is smooth if parents are properly selected and a castration effect is good, a new soybean variety of which the yield per mu is 406kg exceeding the national record can be cultivated, a new record in China is created, and the purposes of rich yield, high yield and stable yield of soybeans are achieved.
Description
Technical field: this is a kind of method of the new varieties that cultivate plants, especially a kind of method of cultivating the high yielding soybeans new varieties.
Background technology: the method for traditional new varieties that cultivate plants roughly has three kinds: the one, and line breeding; The 2nd, crossbreeding; The 3rd, rely on natural variation.Crossbreeding relates to the selection of Parent, as selects improperly, and then all that has been achieved is spoiled, and the method for detassel is more also difficult during hybridization grasps.These bring many difficulties all for the cultivation of new varieties.
Summary of the invention: a kind of method of cultivating the high yielding soybeans new varieties of the present invention, content contain the system of selection of hybrid strain and the emasculating method in when hybridization.The parent selects suitably, castrates effectively just can hybridize smoothly, just might cultivate the new soybean varieties that per mu yield surpasses 406 kilograms of the per mu yields of national highest record, and broken national new record makes soybean reach the purpose of high yield, high yield and stable yields.
Specific implementation method: want to obtain preferably heterosis, hybrid vigor, must interspecific cross when selecting Parent, must have complementary advantages, must be conducive to producing Crossbred hybridization.General soybean, 2 pods account for 70%, 3 pod and account for 20%, 1 pod and account for 10%, and average every pod only has 2.1 of bean or pea.Boil fresh kidney beans (being again the Rice beans) and mung bean seed 12-20 grain is generally arranged.The bean or pea 100-grain weight that boils fresh kidney beans is heavier by 1/3rd than hundred of mung bean, and therefore, choosing is boiled fresh kidney beans and done maternally, and the many pod soybean varieties of breeding are made male parent, carry out first generation hybridization, F
1Reestablish diplomatic relations once again with the many pod soybean varieties of former female parent again, or F
1Reestablish diplomatic relations once with boiling fresh kidney beans again, obtain F
2, from F
2To F
7In the middle of select good strains in the field for seed, select every pod that bean or pea 3-4 or 4-5 grain and then grain-by-grain seed selection are arranged.After the new varieties soybean was cultivated successfully, theoretically, the quantity of mu Yield of Soybean can significantly improve.
Hybridizing emasculating method is, blooms the previous day, and the front end of the flower that boils fresh kidney beans is cut off 1/4th or 1/3rd, not hinder gynoecium as principle, then uses clean writing brush sticky point H
2O
2Put the flower pesticide of immature stamen on the skin, reach the purpose of castration.After boiling fresh kidney beans next day and blooming, hybridize with many pod soybean varieties again.
Claims (2)
1. method of cultivating the high yielding soybeans new varieties is characterized in: do maternally with the fresh kidney beans that boil that beans is more, hybridize as male parent and reestablish diplomatic relations with many pod soybean varieties, from F
2To F
7Through repeatedly selecting good strains in the field for seed and grain-by-grain seed selection, cultivate the high yielding soybeans breeding that every pod has soybean 3-5 grain.
2. method of cultivating the high yielding soybeans new varieties, its emasculating method is: bloom the previous day, the front end of flower is cut off 1/4th or 1/3rd, not hinder gynoecium as principle, then use clean writing brush sticky point H
2O
2Put the flower pesticide of immature stamen on the skin, reach the purpose of castration.
