Description
Summary:Forty eight germplasm collections were evaluated for pod yield and its attributes during summer 2018 and 2019.High heritability coupled with high GAM were observed for pod yield per plant, HPW, HKW and kernel lengthindicating that selection for these characters could be more effective due to additive gene action. Pod yield per plant correlated significantly and positively with SP, SMK, and kernel length to width ratio. Both DFI and DFF correlated significantly and negatively with pod yield per plant. SLA had low heritability and GAM. Genotypes NRCG 14507, NRCG CS 254, NRCG CS 313 and Girnar 1 showed early flowering initiation (35 DAS). The surrogate trait of water use efficiency (SLA) was lowest (15070%). Genotypes NRCG 10620 and TG 39 exhibited higher yields over two summer seasons.
