Abstract
Eleven pigeonpea genotypes in rainout shelter and seventeen genotypes in field condition were evaluated in separate sets for moisture stress and irrigated conditions with two replications for morphophysiological traits related to drought tolerance. Under rainout shelter condition, JSA 59 has low reduction in yield due to water stress, high DTE, low DSI, low membrane injury index, high harvest index and the highest grain yield and total dry matter under stress considered as drought tolerant genotype. The another genotype BSMR 853 was found to be promising for DTE, low magnitude of stress induced yield reduction, high RLWC, low membrane injury index and 2 ranking performance for total dry matter nd but it was poor in respect of grain yield. The culture JSE 115 had better ranking for harvest index, grain yield and RLWC and rate of water loss but it was of intermediate nature for DTE, membrane injury index and per cent reduction in yield due to stress. In turn it ranked 3rd for overall performance in respect of drought character. The culture JSA 41 derived a great attention as it was characterized by high magnitude of DTE, lowest DSI and lowest reduction in yield and fairly high ranking for membrane injury index as well as grain yield performance. It was demerited by lower ranking for RLWC, total dry matter and harvest index. Under field condition, the genotype JSA 59 and K 2 were found better for drought tolerance. The culture BSMR 736 showed 2nd ranking for yield under stress but was demerited by very low rank for all other attributes, whereas, TTB 7 showed high rank for DTE, DSI and per cent reduction in yield but had vary low rank for grain yield and RLWC. It can be concluded that JSA 59 and K2 are the most promising types as drought tolerance under field condition
