Sixteen genotypes of clusterbean were grown during summer season 2016 in RBD design with three replications at experimental field of Plant breeding and Genetics, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya Gwalior. Eight morphological traits i.e., date of maturity, no. of pods/cluster, no. of pods/plant, pod Length (cm), no. of seeds/pod, plant height (cm), canopy temperature (°C), seed Index (100 seed weight(g) were taken for this study. Range, mean, standard deviation & coefficient of variation were subject to this analysis. Study revealed that the significant variation was present among the studied accessions. Coefficient of variation were recorded for specific traits i.e., total no. of pods per plant (61%) followed by total no. of pod per clusters (47.8), no. of seeds per pod (21%) and plant height (35.6%). it is indicated that the sufficient variation was present among the specified traits. Four accessions i.e., RGC-1055 (33.8) followed by RGC-1033 & RGC-197 (36.3) and GST-15-202 (37.2) were observed with reliable canopy temperature under west agro climatic zone in comparison to other studied accessions. Morphological traits were also observed significant variation except date of maturity. Selection can be done based on some traits like no. of pods per plant, total no. of pod per clusters, no. of seeds per pod and plant height. Canopy temperature data is indicated that some accession was also performed well & showed good resistance potential against heat. These accessions can also be emphasized for further study.
