Genetic Parameters and Character Association in Single Cut Sorghum (Sorghum bicolor (L.) Moench)

The present study was carried to know the variability parameters and character association in single cut sorghum varieties under the arid and semi arid condition of Gujarat. Genotypic coefficient of variation (GCV) was maximum for green fodder yield followed by dry fodder yield and their per day productivity. High heritability coupled with high genetic advance and high GCV was observed for green fodder yield followed by dry fodder yield and their per day productivity, leaf breadth and plant height. The green fodder yield showed positive and significant correlation with dry fodder yield, green and dry fodder yield per day, number of leaves per plant, plant height, leaf length and stem girth. It was also observed that characters that exhibited positive associations with fodder yield have also showed positive associations among themselves. The characters like green and dry fodder yield per day and number of leaves per plant were exerted positive direct effects on green fodder yield. Whereas the plant height, leaf length and stem girth showed negative direct effect with green fodder yield, which may be a result of the indirect effect of these traits via other traits.
