To Study Correlation and Path Analysis in Rice Breeding Lines

The experiment was conducted at Research Farm, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). association analysis and genetic divergence among the ninety eight aromatic advanced breeding lines of rice along with popular standard checks namely Indira Sugandhit Dhan-1, Pusa Basmati-1, Badsha bhog, Dubraj, Chinnor, Mahisugandha and Kalanamak. The high estimate of phenotypic and genotypic coefficient of variation was observed from unfilled spikelets per panicle, filled spikelets per panicle, total spikelets per panicle, Spikelet sterility percentage, and grain yield per plant and Brown rice breadth. High heritability with high genetic advance was found for number of total spikelets per panicle and filled spikelets per panicle. Grain yield per plant was positively and significantly associated with 100 seed weight, total effective tillers per plant, filled spikelets per panicle and total spikelets per panicle. The path analysis revealed that Panicle length, Effective tillers per plant, Filled spikelets per panicle, Spikelet sterility percentage and 100 seed weight had high and positive direct effect on Grain yield per plant.
