Genetic variability, correlation and path analysis studies in forage sorghum (Sorghum bicolor (L.) Moench) genotypes

Author(s): PR Patel, DM Suthar, MP Patel and Neha Patel
Abstract: The field experiment consists of 12 treatments evaluated at Pulses Research station, S. K. Nagar, S.D.A.U, Dantiwada to study genetic variability, correlation and path analysis for yield and yield attributing traits. The experiment was conducted by using randomized block design with 3 replications during kharif 2019. The analysis of variance showed high significant differences among genotypes for mostly characters, indicating the presence of sufficient variability. Moderate estimates of GCV and PCV was observed for plant height, green fodder yield and dry fodder yield. While, moderate GCV and high PCV observed for leaf: stem ratio. High heritability coupled with high genetic advance expressed as per cent of mean observed for green fodder yield and dry fodder yield, indicating the preponderance of additive gene action governing the inheritance nature of these characters and selection for these traits would be advantageous for genetic improvement. Plant height, leaf width and green fodder yield exerted positive and significant correlation along with positive direct effect on dry fodder yield. Hence, it would be rewarding to give due importance on the selection of these characters for rapid improvement in dry fodder yield of these crop.
