Abstract:

An experiment was conducted in a randomized complete block design with two replications at experimental area of Research Farm, College of Agriculture, Gwalior, (M.P.) during 2014-2015. The study was undertaken to inheritance of grain yield and its components in thirty six wheat genotypes. Analysis of variance revealed that genotypes were significantly differed for all characters and suggested considerable variability for all yield and its attributing characters in the present material. Among genotypes tested, HI 1610 seems to be the best, because, it is highest yielder, early flowering, early maturing, and bold grain size and dwarf.Almost equal magnitude of GCV and PCV showed for days to heading, 1000 grain weight and days to maturity indicating that these characters are less influenced by the environment while grain yield and plant height exhibited high value of PCV over its GCV value, indicating relatively large amount of variation for these characters was due to environment alone. The Higher heritability was observed for days to heading, 1000 grain weight and plant height. High heritability coupled with high genetic advance recorded for traits 1000 grain weight, plant height, days to heading and grain yield and that these characters are governed by additive gene effects; a directional selection for these traits would be more effective for desired genetic improvement.
