ASSOCIATION ANALYSIS FOR DRY MATTER PRODUCTION AND DISTRIBUTION IN SORGUM

Abstract

Twelve advanced varieties of sorghum were studied for their genetic potentiality of dry matter production and its association with grain yield. The genotypes showed differential response to biomass production and grain yield. SPV. 351 was identified as the best. The dry matter accumulation in the panicle accounted for the major proportion of the total DMP: A positive correlation between total DMP and grain yield was established. Panicle dry matter had the largest direct effect on grain vield. Plant height was negatively associated with grain yield but its direct effect on grain yield was positive.
