从大豆产量是光合产物的基本生物学原理出发。本文指出以生物产量和经济系数的提高作为产量育种目标,并在各主要环节进行量化数据测定,决定取舍,是提高工作效率的合理化途径。实践中,采用收获重和收获指数代替生物产量和经济系数的概念是方便并且合理的。十年的资料证明:在目前生产水平上,育种材料的的产量与收获重有极高的相关性。初步实践效果也表明,以收获重和收获指数为目标进行产量育种育成高大繁茂生育期适中而又杆强不倒的高产品种是有效的。
Proceeding from the basic biological principle of photosynthate for soybean yield. This paper points out that taking the improvement of biological yield and economic coefficient as the goal of yield breeding and the determination of quantitative data in all the major links determine the choice is a reasonable way to improve work efficiency. In practice, the concept of using harvest weight and harvest index instead of biological yield and economic coefficient is convenient and reasonable. Ten years of evidence have shown that at the current level of production, there is a very high correlation between yield and harvest of the breeding material. The initial practical results also show that the yield and harvest index as the goal of yield breeding bred tall and lush growth period moderate but strong and not down the high yield varieties is effective.
