Author(s): Dindu Vamsi Krishna, K Prasada Rao and Eugenia P Lal
Abstract: Drought is the major constrains faced in rainfed areas so Screening of genotypes for drought tolerance is the need of the day, by using physiological traits as a parameter The present investigation was designed out in in-vitro and in-vivo conditions. In-vitro PEG6000 is used as a drought inducer to screen 17 genotypes based on seed vigour 7 best genotypes were selected for in-vivo. Field trail with 7 genotypes Based on field capacity different water treatments are taken to impose drought stress on green gram genotypes such as 100%, 80%, 50% and 30% irrigated conditions Among the genotypes protein content % KM-1423 and IPM 02-3, carotenoids KM-1423 and KM-1409, relative water content KM-1423 and IPM 02-14, chlorophyll a KM-1423 and KM-1415 and chlorophyll b, KM-1423 and IPM 02-14, Total chlorophyll KM-1423 and IPM 02-14 and proline content were found as KM-1423 and IPM 02-14. Over the genotypes KM-1423 found to be highly suitable for under both irrigated as well as rain fed conditions.
