The present study, combining ability estimates were worked out through Line × Tester analysis of 32 hybrids developed by crossing eight lines with four testers to know the genetic architecture of 11 morphological traits under coastal saline condition. The present study was conducted at Plant Breeding Farm, Department of Genetic and Plant Breeding, Faculty of Agriculture, Annamalai University to estimate combining ability, gene action and proportional contribution of cross components in rice genotypes under coastal salinity. | Yield response of rice genotypes for gene action under coastal saline condition
