A STUDY ON THE CORRELATION BETWEEN SEED—STEMS RATION AND OTHER AGRONOMIC CHARACTERS IN SOYBEAN
Yang Qing-kai Meng Qing-xi et al.
Ten soybean varieties were tested in four ecologically different locations from 1973 to 1975. The results showed that the correlation between seed-stems ratio and height, nods per main stem, No of branches, pods per branch depended on ecological enviroments. In locations where the enviromental conditions fit saybean, the soil is fertile, the correlation coefficienets are always negative, while in other locations the enviromental coditions don't fit for soybean, the correlations arepositive. In general, the correlations between seed-stem ratio and pods per main stem, pods per plant, the pods of branch and pods of main stem ratio, seed yield are positive and the more fertile the soil is, the more evident the positive correlation. Application of this knowlege in soybean breeding was discussed.
