Unveiling genetic associations for enhanced grain yield in soybean [Glycine max (L.) Merr.] Germplasm

Abstract

An experiment entitled “Unveiling Genetic Associations for Enhanced Grain Yield in Soybean [Glycine max (L.) Merr.] Germplasm” was carried out during Kharif 2023-24 at the research farm experimental farm of the College of Agriculture, Badnapur. Vasantrao Naik Marathwada Krishi Vidyapeeth Parbhani (M.S). The experiment was laid out in Randomized Block Design (RBD) with 38 genotypes and two replications to estimate the association between grain yield and yield contributing characters. In this experiment, genotypic correlation coefficients were higher than the phenotypic correlation coefficients. According to correlation results, grain yield per plant was significantly and positively correlated with Number of pod per cluster, Number of pod per plant, 100 seed weight, Harvest index, Number of seed per pod at both genotypic and phenotypic levels.
