Abstract: The present inves Stigation entitled as “Physiological evaluation of wheat genotype under normal irrigated and non-irrigated conditions” was carried out in rabi season of 2017-18 at Wheat Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). It is carried out under two sowing environment i.e. normal irrigated and non-irrigated condition and 25 wheat genotypes viz., HD 3237, DBW 166, JWS 810, RIL-S1-126, DBW 110, DBW 93, WH 1235, MP 3288, GW 477, NIAW 3170, K 1317, DBW 136, HI 1620, M 516, DBW 252, NI 5439, RIL-S1-38, MACS 6696, RW 5, NIAW 3212, BRW 3806, C 306, MACS 6695, HI 1628, MP 133 were tested. The experiment was laid out in Simple lattice design with two replications.
Different yield and physiological traits viz. germination, days to heading, days to anthesis, days to maturity, plant height, number of productive tillers at maturity, number of grains per spike, grain weight/ spike, 1000 grain weight, biological yield, grain yield, harvest index, chlorophyll content index (at 15 and 21 days after anthesis), canopy temperature (at 15 and 21 days after anthesis) may be used in research programme for development of moisture tolerant genotypes for changing climatic scenario.
The growth, yield attributes and physiological attributes showed significant increase when wheat crop was sown under normal irrigated condition. Grain yield obtained was significantly higher in sowing under irrigated condition. Wheat crop sown at irrigated condition showed lowest canopy temperature (at 15 and 21 days after anthesis) as compare to sown under non-irrigated condition. Sowing of wheat crop under irrigated condition was found to be most economical.
Out of 25 genotypes tested under experiment, genotype GW 477 was superior over other in respect of number of productive tillers, number of grains per spike, grain weight/ spike, grain yield, harvest index as compare to other genotypes under normal irrigated condition. In non-irrigated condition, MACS 6696 superior in respect of grain yield, harvest index and chlorophyll content index at 21 days after anthesis
