CORRELATION AND PATH ANALYSIS FOR YIELD AND YIELD COMPONENTS IN RICE (ORYZA SATIVA L.)

ABSTRACT
Correlation studies in rice revealed that genotypic correlation coefficients were higher than
phenotypic correlation coefficients for most of the characters under study. Character association
analysis revealed significantly positive association of grain yield per plant with number of productive
tillers per plant, 1000-grain weight, panicle length and number of grains per panicle. Correlations
among yield components were positive, encouraging rapid improvement of yield. Path analysis
revealed that number of grains per panicle, days to 50 per cent flowering, 1000-grain weight and
number of productive tillers per plant have shown high positive direct effects on grain yield
phenotypic correlation coefficients for most of the characters under study. Character association
