CORRELATION AND PATH ANALYSIS IN RICE (Oryza sativa)

Abstract

Three lines 12 testers and their 36 hybrids of rice were studied for correlation and path analysis for grain yield using ten characters. Grain yield was significantly and positively correlated with panicle length, spikelets per panicle, grains per panicle, 100-grain weight and harvest index. Grains per panicle was the main component character affecting yield directly. High and positive indirect effects were contributed by panicle length and spikelets per panicle through grains per panicle.
