Description The experiment was conducted to identify the waterlogging stress tolerant genotypes in pigeonpea. Waterlogging treatment was given to the plants at vegetative stage after treatment the survival rate was assessed. Out of 128 germplasm pool, 38 survived and the survival rate was estimated along with Mahalanobis D2 cluster analysis. The range of survival percentage for both pot and field were found between 26.6 and 73.3 with the standard deviation of 14.82 for pot screening and 14.29 for field screening. The pot survival percentage mean for all 38 accessions were found higher than field survival which clearly indicates that environment poses an effect on the performance of the genotypes. The Mahalanobis cluster analysis revealed five clusters. Out of five clusters, two were found comparatively tolerant than the others. The tolerant germplasm can also be used as donor parents in hybridization programs for development of water logging-tolerant genotypes. The identified tolerant germplasms may be utilized to incorporate waterlogging tolerance in the short-duration pigeonpea pool.
