Pigeon pea is an important and highly water logging sensitive legume crop in Madhya Pradesh. The investigations were carried out to examine the responses of pigeon pea genotypes under normal and waterlogged conditions in 12 pigeon pea (Cajanus cajan) genotypes to identify the susceptible and tolerant cultivars with the improvement strategies for them. The study of phenological traits indicated that the genotype ICPL 87051 took minimum days for 50% flowering (85.50 and 87.83 days) and C 11 required minimum days for physiological maturity (122.00 and 124.83 days) and field maturity (135.67 and 141.83 days) while genotype KPBR 80-2-1 had however late for (157.83 and 162.17 days), physiological maturity (195.83 and 196.33 days) and field maturity (212.00 and 215.00 days) under normal and waterlogged conditions respectively. Days to 50% flowering, days to physiological maturity and days to maturity were shown significant positive correlation among them under both the conditions.
