Genetic Variability and Correlation Studies in elite ‘B’ and ‘R’ lines in Kharif Sorghum
The genetic variability and nature of character association was studied in 20 B lines and 16 R lines of kharif sorghum(sorghum bicolor (L) Moench). The genotypic variance was lower than the phenotypic variance for all the characters.High genotypic and phenotypic variance, heritability and genetic ad...

| description | The genetic variability and nature of character association was studied in 20 B lines and 16 R lines of kharif sorghum(sorghum bicolor (L) Moench). The genotypic variance was lower than the phenotypic variance for all the characters.High genotypic and phenotypic variance, heritability and genetic advance were observed for the characters paniclelength, fodder yield, primary branches per panicle, grains per primary branches, harvest index, grain yield and plantheight indicating that additive gene effects were operating for these traits. Positive and significant correlation betweengrain yield and harvest index, total biomass, fodder yield and leaf area index was observed both at phenotypic andgenotypic level, while the characters field grade score ,threshed grade score and days to 50% flowering exhibitednegative correlation with grain yield. |
