Abstract:
An experiment was executed with 36 (Thirty six) soybean (Glycine max L. Merr.)
genotypes at Bangabandhu Sheikh Mujibur Rahman Agricultural University by the
period from December 2020 to April 2021, Salna, Gazipur. The aim of this study is to
find the genetic variability, correlation and path coefficient analysis, for detecting the
genetically diverse parents with elite agronomic performance and to find out the
characters accountable for genetic divergence. The analysis of variance showed highly
significant differences among the mean values for all traits. 36 (Thirty six) soybean
genotypes for all the estimated traits shown high heritability, high to low genetic advance
along with high to moderate GA%. This finding indicated that those traits were governed
by additive gene so selection might be useful. As per the experiment number of
branches/plant (0.08), number of nodes/plant (0.31), number of seeds/plant (0.07), 100
seed weight (g) (0.16) and seed yield/plant (0.45) were the important characters
accountable for genetic divergence. Among the 6 (six) clusters, the highest inter cluster
distance was observed between in cluster I and cluster VI (20.01) and the lowest between
cluster V and cluster VI. For the highest seed yield/plant G1, along with the other
genotypes belonging cluster III (G8, G13, G33) will be worthwhile selection for future
crop improvement program.
