利用有性杂交方法创造新的变异类型、选育新品种,是目前花生育种工作中普遍采用的主要方法之一。 花生的花,构造较复杂,龙骨瓣把雌蕊雄蕊包得很紧,能授粉的花药有4长4园共8枚,在进行人工杂交时,留着龙骨瓣进行去雄工作,往往不大方便操作,也就是说对工效有一定影响(尤其对工作不熟练的人来说影响较大) 另方面丛生型花生一般主茎可以开花,埋在土里基节的花蕾可以进行闭花授精;花生的花朵花柄极短,开花时,花冠下面像花柄的那条花萼管,在花朵开放的当天下午即枯萎;早期开的花多密集在主 It is one of the main methods commonly used in peanut breeding to create new types of mutation and to breed new varieties by sexual hybridization. Peanut flowers, the structure is more complex, the keel petals pistils are very tight, capable of pollination of anthers have 4 long 4 Park a total of 8 in the artificial hybridization, leaving the keel flap to the male work is often not easy Operation, which means that there is a certain effect on the work efficiency (especially for those who work unskilled) On the other hand Cong Sheng peanut stem can flowering, buried in the ground section of the flower buds can be closed flowers insemination; peanuts Flowers very short pedicel, flowering, the corolla below the corolla tube like that stalk, in the afternoon on the opening of the flowers that withered; the early opening of the flowers are more dense in the Lord
