Correlation and Path Analysis for Yield and Related Traits in Upland Rice (Oryza Sativa L.) Varieties

Abstract

The study was carried out on twenty varieties of upland rice (oryza sativa L.) to find out the correlation and path co-efficient values among the grain yield and its’ components. Genotypic and phenotypic coefficients of variation ranged from 6.44 (days to maturity) to 30.47% (yield per plant) and 6.51 (days to maturity) to 30.67% (yield per plant), respectively. High genotypic and phenotypic coefficients of variation with low magnitude of differences between the two were observed for days to maturity, yield per plant and number of filled grains per panicle. Highly significant (P
