Drought Tolerance of Maize Genotypes for Yield and Yield Parameters Using Line Source Sprinkler Irrigation Technique

Forty maize genotypes were studied for influence of moisture stress on yield and yield characters using line source sprinkler irrigation technique during rabi-summer, 2016-17 and 2017-2018 using line source sprinkler irrigation technique. The genotypes, G32-DMIL 50, G16-DMIL 13, G39DMIDS 28, G4-DMIL 78, G28-DMIT 01, G38-DMIDS 15, G15-DMIL 23, G21-DMIL 47, G24-DMIL 84 and G37-DMIDS recorded higher yield compared to other genotypes. The genotype G32DMIL 50 found promising under various moisture regimes. The genotype G32DMIL 50 (96.50) and G16DMIL 13 (91.80) recorded significantly higher cob weight (g/cob) at M1 moisture regime whereas, significantly lower cob weight (g/cob) was recorded in genotype G6DMIT 30 (17.82), G12DMIL 58 (18.45), G5DMIL 150 (19.42), G19DMID 16 (20.75), G7DMIL 112 (22.15) and G17DMIL 52 (22.23) at M5 moisture regime. G21DMIL 47 (315.89), G28DMIT 01 (314.83) and G24DMIL 84 (311.70) recorded significantly higher number of seeds per cob and G6DMIT 30 (96.67) and G19DMID 16 (116.05) recorded significantly lower number of seeds per cob. Genotypes G12DMIL 58 (87.30), G38DMIDS 15 (85.01), G39DMIDS 28 (84.99), G26DMIL 63 (84.80), G24DMIL 84 (83.83) and G4DMIL 78 (83.44) recorded significantly higher shelling percentage.
