Selection and Evaluation of the Relative Influence of the Morphological Characters and Yield Components on Yield in Soybean (Glycine max.(G) Merr.)

Abstract

                                Sixty promising soybean varieties were evaluated in a randomised block design with two replications during kharif seasons of 1972 and 1973 at the I. A, R. I. Regional Station. Coimbatore. Morphological characters viz.. plant height number of branches and days to flowering showed significant positive correlation with yield due to higher positive direct and indirect effects via other characters. Due to the inter-related positive and negative, direct and indirect effects via other characters, yield components showed very low correlation values with yield. The varieties PLSO-18, UPSS-69. EC-25683 and EC 18737 were promising for their higher yields and other desirable characters.
