Estimate of Genetic Variability and Heritability in Some Exotic Germplasm Lines in Kharif Rice (Oryza Sativa L.).

The high genotypic coefficient of variation, high heritability with high genetic advance as percent of mean was observed for grain yield per plant, total tillers per plant, productive tillers per plant and grains per panicle, whereas days to initiation of flowering, days to 50 % flowering and days to maturity had high heritability with low genetic adavance as per cent of mean.

Correlation and Path Coefficient Analysis for Yield and Yield Components in Segregating (F4) Generation of Lablab Bean (Lababperpureus L. Sweet).

The genotypic correlation coefficients were slightly higher than phenotypic coefficients. Seed yield per plant was highly significant and positively correlated with number of pods per plant, primary branches per plant, hundred seed weight, days to maturity and number of peduncles per plant at both genotypic and phenotypic level, whereas it was significantly and positively correlated with days to first flowering at genotypic level only. Path analysis revealed that, number of pods per plant, hundred seed weight and number of primary branches recorded the highest direct effects in desirable direction. Their association with seed yield was also significant and positive indicating true and perfect association between these traits. Therefore direct selection for these characters would help in isolating high yielding genotypes.
