Agro-morphological and biochemical characterization and principal component analysis for yield and quality characters in fine-scented rice genotypes

Forty-one fine-scented rice genotypes were evaluated for 18 agro-morphological and quality characters characterization, 21 quantitative principal component analysis in R-studio software. Characterization of traits viz., plant height, days to 50% flowering, panicle length, number effective tillers per plant, test weight, grain breadth, L: B ratio, kernel dimensions, awns, colour distribution alkali spreading value, gel consistency, aroma, amylose content showed huge diversity among the genotypes. PCA revealed that PC1 highest amount variance (32.0%) followed by PC2 (15.7%), PC3 (9.0%), PC4 (8.1%), PC5 (7.8%), PC6 (5.4%) characters. Out components, only 6 an eigenvalue greater than 1 contributes about 78.1% total Genotypes higher values ratio ratio. Similarly, variable like yield plot content. harvest index, no. head recovery. breadth flowering. elongation filled grains panicle. a square meter panicles meter. This pre-breeding characterization study may be useful finding potential which are having both breeding high-yielding varieties with good-quality
