THE RELATIONSHIP BETWEEN DRY MATTER ACCUMULATION AND YIELD AMONG DIFFERENT GENOTYPES OF SOYBEAN

Open publisher page 1 citations

Abstract

Three soybean varieties were tested in the experiment station of Northeast Agricultural University. The results showed that yield was significantly correlated with biomass and harvest index, especially the latter. LAI of soybean was significantly correlated with yield, but yield began to decline when LAI was too high. Dry matter weight of fulling period was correlated with yield. Maxim CGR was significantly correlated with yield. NAR and RGR were correlated with yield.$$$$
