Title : Interaction and Analysis of Direct and Indirect Contributions of Shoot Fly Resistance Traits on Sorghum Fodder Yield

Abstract :

This research investigated the interrelationship between sorghum yield, traits related to shoot fly resistance, and their combined influence on green fodder yield. Two hundred and ten Recombinant Inbred Lines (RILs) were evaluated during the kharif season of 2018 at the Instructional Dairy Farm of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India. Correlation among 18 measurable traits was computed along with the direct and indirect effects of seventeen independent traits on green fodder yield. Green fodder yield exhibited highly significant positive correlation with dry fodder yield followed by stem diameter. Path coefficient analysis revealed that dry fodder yield, stem diameter, days to emergence, plant height, leaf length, leaf width, 1000 grain weight have direct positive effect on green fodder yield. Selection based on these traits, either individually or in combination, could effectively identify high-yielding lines for green fodder production, contributing to enhanced shoot fly resistance in sorghum breeding programs.
