ASSESSMENT OF GENETIC VARIABILITY IN F5 GENERATION UNDER TRANSPLANTED CONDITION IN RICE (ORYZA SATIVA L.)

The present study was conducted to estimate genetic variability for different characters, to estimate heritability and genetic advance and to identify promising genotypes suited for transplanted condition in rice.The study has been carried out on F 5 families consist twenty-six families from thirteen crosses along with four checks were evaluated in two replication.Analysis of variance indicated that the mean square due to between family were highly significant for all characters under study, which revealed the presence of significant genetic variability between the families.Intra class correlation lead the interference that differences between individuals within family is small and each family differentiated distinctly from the other at higher level in F 5 generation.Moderate GCV and high PCV were recorded for gain yield plant -1 and moderate for others.High heritability was recorded for days to 50% flowering, days to maturity, 1000 grain weight (g), number of spikelets panicle -1 , grain yield plant -1 (g), number of filled grains panicle -1 , plant height (cm) and moderate for others.Genetic advance as percentage of mean were high for grain yield plant -1 , number of filled grains panicle -1 , 1000 grain weight (g), number of spikelets panicle -1 , days to 50% flowering and moderate for other characters.Grain yield plant -1 (g) was character which recorded moderate GCV and high PCV, heritability and genetic advance as influenced by additive gene action selection would be effective.Hence, nine families exhibited superiority over check for grain yield plant -1 (g) and other yield attributing characters were identified for advancement in next generations.
