Association analysis for yield and its contributing traits in rice (Oryza sativa L.)

Author(s): Yadunandan Verma, Vivek Kumar Kujur and Guman Singh
Abstract: The entitled research work “Association analysis for yield and its contributing traits in rice (Oryza sativa L.)” was executed Research cum Instructional Farm, Department of Genetics and Plant Breeding, IGKV Raipur (C.G.) during kharif 2021. The research material under research comprised of 50 rice germplasm lines including two checks namely Mahamaya and Rajeshwari, which were tested in RBD with two replications The observation of research investigation were recorded for total 8 characters viz. Days to 50% flowering, Number of tillers per plant, Panicle length (cm), Plant height (cm), 1000 seed weight (g), Grain yield per plant (g), Biological yield per plant (g), Harvest index (%). Positive significant correlation was showed Grain yield per plant with Number of tillers per plant, 1000seed weight, biological yield per plant. These characters would be beneficial for increasing yield and choosing superior genotypes among rice cultivars. Positive direct effect on Grain yield per plant showed by the Harvest index, biological yield per plant, Panicle length, Days to 50% flowering, Number of tillers per plant, 1000seed weight revealed true relationship between them and direct selection for these traits would be beneficial for increasing yield.
