An experiment was conducted during November 2013 to March 2014 at the experimental field of Sylhet Agricultural University (SAU), Sylhet to observe the differences in relation to seed colour, cotyledon colour, seed shape, flower colour, petiole and inflorescence length, pod shape and size, yield performances etc. among the five lablab bean genotypes viz., SB003, BP003, SB008, SB010 and IPSA Sheem-2. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The genotypes SB003 and SB008 had reddish brown seed coat colour while it was reddish for BP003 and black for SB010 and BARI Sheem-1. Among the genotypes 100 dry seed weight was ranged from 30.00 g (BARI Sheem-1) to 41.30 g (SB003). Variation in pod and seed yield potentiality was also found among five lablab bean genotypes. The genotype SB008 produced the maximum number of pods plant-1 (263.3) followed by BP003 (256.3) but plant-1 pod yield was maximum for the genotype BP003 (1.78 kg) followed by SB008 (1.68 kg). This variation was due to the individual pod weight. The highest pod yield was recorded in the genotype BP003 (11.86 t ha-1) while it was the lowest in the genotype SB003 (9.0 t ha-1). For seed production potentiality, the genotype SB008 produced highest amount of seed plant-1 (242.97 g) since it produced the maximum number of dry pods plant-1 (141.18).
