Enhancing rice strains to create elite varieties that combine both qualitative and complex traits, such as increased yield, is feasible by harnessing the genetic diversity within the population. This study focused on evaluating genetic variability and the relationships between grain quality and yield traits in 50 rice landraces. Data were collected on eleven traits contributing to yield and eleven parameters related to grain quality. The analysis of variance revealed significant variability across all measured traits. Yield-related traits, particularly the number of tillers per plant, total grains per plant, number of panicles per plant, number of filled grains per plant, grain yield per plant, and test weight, exhibited substantial genotypic and phenotypic variation. Similarly, grain quality traits such as amylose content, gelatinization temperature, and gel consistency also displayed notable variation. Most traits, except the number of tillers and panicles per plant, demonstrated high heritability. Furthermore, grain yield per plant showed a strong positive correlation with the number of tillers and panicles per plant at both genotypic and phenotypic levels. https://www.agriculturejournal.org/volume12number3/genetic-variation-for-grain-quality-and-yield-attributing-traits-in-upland-rice-oryzasativa-l-landraces-of-nagaland/ Correlation; Quality; Rice; Variability; Yield
