Greengram is one of the most important pulse crops of India. It has low genetic variability and harvest inde x Interspecific crosses allows the exploitation of useful genes from wild species and to create the genetic variability in the cultivated ones. The hybridization was done between VBN (Gg) 2 × Vigna radiata var. sublobata, a progenitor species of greengram used as a resistant parent for bruchid infestationto develop pre-breeding material. The stabilized lines of the above cross were evaluated during kharif, 2019 in Department of Pulses, Tamil Nadu Agricultural University, Coimbatore. A total of 53 inter sub specific lines were raised in randomized block design with two replications. Ten biometrical traits were recorded for all the 53 lines and were statistically analysed. A wide range of mean values were observed for all the traits. Phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the characters indicating the influence of environment on all the traits. The traits viz., days to 50% flowering, plant height, number of clusters per plant, number of pods per plant, 100 seed weight and single plant yield showed high heritability coupled with high genetic advance as per cent of mean. The results on genetic analysis and trait based classification of pre- breeding lines of the present study could be used to improve yield traits and bruchid resistance in greengram.
