Principal component analysis of JNPT lines of rice for the important traits responsible for yield and quality
2021
In present study, 67 JNPT (Jawahar New Plant Type) lines were evaluated for 28 morphological and quality traits planted in RCBD with three replications. Principal Component Analysis (PCA) revealed that out of 28, only eight PCs exhibited more than 1.0 eigen value and showed about 81.84% total variability. For selecting the high yielding genotypes in rice, the characters viz., spikelet density, spikelet fertility, number of tillers plant⁻¹and panicle weight plant⁻¹ may be considered. On the basis of high PC score ten most prominent lines namely JNPT-1059-9, JNPT-1059-10, JNPT1062-1, JNPT-1062-2, JNPT-1064-9, JNPT-1065-1, JNPT-1065-2, JNPT1065-3, JNPT-1066-52 and JNPT-1068-65 were identified for yield and quality traits.
