大豆因其种子繁殖系数低而影响了良种的推广速度及生产的发展,为此,在进行春大豆良种繁殖时应注意选用最佳的繁殖方案,采用先进的技术措施。 1 平行繁殖法平行繁殖法是指在进行试验的同时,并列进行种子的繁殖工作。它能大大加快新品种的繁殖速度。平行繁殖一般在保护行和保护带中进行,这样省工、省地、省时,还可以加强保纯防杂工作。如种子量较大,条件具备,应提倡单独选地繁殖。
Soybean because of its low coefficient of seed propagation affect the promotion of seed and the development of production, therefore, in the spring soybean breeding should pay attention to the selection of the best breeding programs, the use of advanced technical measures. A parallel breeding method The parallel breeding method refers to the conduct of experiments at the same time, side by side the breeding of seeds. It can greatly speed up the breeding of new varieties. Parallel breeding is generally carried out in the protection of the line and the protection zone, so that workers, land, save time, but also can enhance the protection of pure anti-miscellaneous work. If the seed is large, the conditions are met, we should advocate the election of breeding alone.
