Correlation and path coefficients analysis for reproductive traits in Guinea grass

Abstract

Correlation and path coefficients were calculated for seed yield per plant and its components from 36 clones comprising 8 parental and their 28 single cross clones in Guinea grass (Panicum maximum Jacq.) from data pooled over two years. Seed yield per plant showed significant positive correlation coefficients with branch number per panicle, panicle number per plant, panicle length, branch length, 100 seed weight and day to flower. Path coefficients analysis revealed that panicle number per plant had highest direct effect on seed yield per plant, followed by branch number per panicle, days to flower and 100 seed weight.
