摘要
本试验研究了不同基因型大豆经济系数、实际收获指数、表观收获指数、粒茎比等七种转化系数及产量间的相关性。结果表明可以通过对表现收获指数的选择,获得经济系数、实际收获指数.粒茎比和产量的增益.表观收获指数在大豆育种中(尤其是高光效育种)可作为衡量产量的指标.
The correlation analysis between seven conversion indexes(economic inde-xe,actual harvest ind x,apparent harvest index,ratio of seed to stem,etc.)and yield of different genotypes of soybean has been studied in our experiment.The results showed that,the gains in economic index,actual harvest index,ratio of seed to stem and yield can be obtained through the celection to apparent harvest index.Therefore,the apparent harvest index can be used as a indicator measuring yield in soybean breeding,esp.in the breeding to improve soybean photosynthetic ability and yield.
