Abstract: The experiment was conducted at Research Farm, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.).To assess the genetic variability 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 mean sum of squares due to the genotypes were highly significant for all the characters studied namely, Days to 50 percent flowering, Plant height, Panicle length, Total tillers per plant, Effective tillers per plant, Filled spikelets per panicle, Unfilled spikelets per panicle, Total spikelets per panicle, Paddy length, 100 seed weight, Grain yield per plant, Paddy breadth, Spikelet sterility percentage, Paddy L/B ratio, Hulling %, Brown Rice Length, Brown Rice breadth, Brown Rice L/B ratio, Milling %, Kernel length, Kernel breadth, Kernel L/B ratio, Elongation Index, Kernel breadth after cooking, Cooked Kernel L/B ratio, Elongation ratio and Kernel length after cooking. 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.
Keywords: phenotypic and genotypic coefficient, heritability, genetic advance
