Abstract:
Information of the nature and degree of variability present in the population helps in selection of base material with the desirable characters which in turn determines the success of any breeding programme. We evaluated performance, variability, heritability, genetic advance, correlation coefficient and path coefficient for 18 agromorphological characters in twenty-one rice mutant lines and their parents along with 2 checks during 2018 and 2019. High values of PCV and GCV for number of tillers and effective tillers; and low for flag leaf width, flag leaf length spikelet fertility %, days to maturity and number of sterile spikelets per panicle were recorded. High heritability along with high genetic advance as percent of mean was recorded for milled grain width, grain yield per plant, fertile spikelet/ panicle, number of tillers, number of effective tillers, paddy width, plant height, paddy length, days to maturity, days to 50% flowering, decorticated grain length and milled grain length during both the year.
