Genetic parameters for yield and its correspondent characters in rice were estimated from a trial with two CMS, twenty testers and forty hybridscross evaluated for ten characters related to yield. The highest GCV was recorded for grain yield plant-1. High heritability and the low genetic advance were recorded for grain yield plant-1, spikelet fertility, plant height, harvest index, seedling height, flag leaf area, panicle bearing tillers plant-1, test weight and panicle length suggesting apredominance of non-additive gene action in the inheritance of these traits.

Abstract


Genetic parameters for yield and its correspondent characters in rice were estimated from a trial with two CMS, twenty testers and forty hybridscross evaluated for ten characters related to yield. The highest GCV was recorded for grain yield plant-1. High heritability and the low genetic advance were recorded for grain yield plant-1, spikelet fertility, plant height, harvest index, seedling height, flag leaf area, panicle bearing tillers plant-1, test weight and panicle length suggesting apredominance of non-additive gene action in the inheritance of these traits.
