Genetic Evaluation of Inter Sub-specific Derived RILs Population for Yield and Quality Attributes in Rice

This study emphasized to decipher yield and quality attributing traits of rice and to evaluate genotypes based on combination of phenotypic traits. Genetic parameters were evaluated from 61 F₁₀RILs population derived from a cross between, JNPT 100 (Tropical japonica) and HMT (indica). High heritability in broad sense coupled withhigh GA as percentage of mean was recorded for certain traits indicating heritability is due to additive gene action and selection may be effective. Visualising results of correlation analysis and path coefficient analysis we can say that traits such as number of spikelets per panicle, panicle weight per plant, panicle index, elongation ratio, head rice recovery % and number of leaves per plant showed positive direct effect on grain yield along with positive significant correlation with grain yield, indicate that these are primary yield contributing traits and selection for above traits might be utilized as inbred for production of hybrids in rice.
