Development of waterlogging tolerant lines of pigeonpea for Eastern India

Abstract

Pigeonpea is very sensitive to waterlogging. At pan India level, approximately 25-30 per cent area of pigeonpea is prone to excess moisture stress. Atotal of 63 germplasms/genotypes were evaluated along with IPAC-79 as the waterlogging tolerant check under controlled partial submergence condition and under waterlogged field condition for selection of waterlogging tolerant pigeonpea lines. Data were recorded for survivability, days to anthesis, per plant seed yield and maturity period. Pigeonpea genotypes ICARPP01, ICARPP02 and ICARPP03 were found promising. ICARPP01 produced highest biomass per plant (746.5g), pods/plant (924.6) and seed yield per plant (151g). The genotype ICARPP01 took minimum number of days for anthesis (124 days) and maturity (197days), whereas the check variety IPAC-79 recorded maximum number of days to anthesis (201 days) and maturity (255 days).
