Abstract: An experiment was conducted at Instructional Farm of BCKV, Mohanpur, West Bengal with five genotypes of black gram during summer season of 2007 and 2008. The six environments were created through two row spacing and application of nitrogen. Here, the dwarf determinate genotype VK-6 exhibited the highest seed yield per plant (2.87 g) and yield plot-1 (60.53 g) among six environments followed by VK 1, Sarada, T-9 and VK-3. The stability parameters in respect to yield attributing traits revealed that VK-6, Sarada, VK-3 and T-9 for harvest index, T-9 and Sarada for seeds per pods, VK-3 for pods per plant, VK-1 and VK-3 for number of branches per plant was recorded stable performance over the environments having regression coefficient near to unity and deviation from regression around zero.
