Abstract
An experiment was conducted during March 2014 to August 2014 at the experimental field of Sylhet Agricultural University (SAU), Sylhet to study the morphological variability, yield and yield contributing characteristics among the four lablab bean genotypes viz., SB003, SB010-1, SB011 and BP003. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The genotypes SB003 and SB010-1 had reddish brown seed coat color while it was black in SB011 and reddish color in the genotype BP003. Among the genotypes 100 dry seed weight was ranged from 34.00 g (SB010-1) to 42.00 g (SB011). Variation in yield and yield contributing characteristics were found among four lablab bean genotypes. The genotype SB003 produced the maximum number of pods plant-1 (206.3) followed by SB010-1 (134.3) while it was minimum for the genotype SB011 (92.67). Similar trend was also noticed in case of pod yield plant-1 among the genotypes. The highest pod yield was recorded in the genotype SB010 (7.73 ton ha-1) while it was the lowest in SB011 (2.87 ton ha-1). However, pod yield ha-1 indicating bright scope to popularize lablab bean production during early kharif in Sylhet region.
