试验结果表明，大豆育种材料的籽粒产量与其生物产量间，存在高度显著正相关关系．大垄栽培方式和肥水不高是这种相关关系的背景、鉴于肥水条件不会在短期内有较大的改善，提出大豆高产育种从亲本选配开始，即应遵循一种以生物产量为主要指标、在各个环节上都进行定量选择的工作程序． The results showed that there was a highly significant positive correlation between the grain yield of soybean breeding material and its biological yield. Large-ridge cultivation methods and low fertilizer and water are the background of this relationship. In view of the fact that fertilizer and water conditions will not be greatly improved in the short term, it is suggested that breeding of high-yielding soybean should begin with the selection of parents, that is, Indicators, in all aspects of the quantitative selection of work procedures.
