Abstract

One hundred eighty two exotic soybean accessions were evaluated for yield and yield attributing traits. The data was analysed for mean, range, correlation coefficient and path coefficient analysis. Plant height, number of branches per plant and number of pods per plant showed positive and significant association with yield. Number of days to flowering, number of day to maturity and 100 seed weight showed positive and non significant association with yield. The path coefficient analysis revealed that the highest direct effect on grain yield was exhibited by numher of pods per plant, 100 seed weight, number of days to maturity and plant height. Among seven characters studied, the number of pods per plant and plant height are two important traits contributing for yield. Based on the performance of 182 exotic lines, 30 promising lines were found superior for yield.
