Variability, Correlation and Path Analysis for Several Quantitative Traits Derived Multi-Parent Advanced Generation Inter-Cross (Magic) F2 Population of Rice (Oryza sativa L.)

Eight quantitative traits of an F2 MAGIC population in rice were subjected to analyze variability, correlation and path analysis. The results third fourth degree statistics (skewness kurtosis) showed that Individual dried straw weight, 1000-seed grain yield, Number effective tillers are associated with complementary gene interaction, requiring intense selection, while Plant height, Panicle length, Spikelet fertility percentage, Harvest index duplicate (additive x additive) interactions, suitable for mild selection. Leptokurtic distribution per plant, Pancile length percentage revealed the large number genes governing traits. Platykurtic yield indicated fewer controlling However, when it comes H2 GAM, high values seen could be explained by additive action achieved through mass High heritability lower GAM weight non-additive limiting chances direct For Pearson correlation, no other highly correlated plant (0.864**) (0.828**). highest total effects on (2.7437) (1.0865). had effect at 1.0734, most indirect weight.
