The present investigation was planned to assess the principal component for yield, yield contributing traits and quality traits in thirty genotypes of rice suitable for aerobic condition. The genotypes were procured from Directorate of Rice Research, Hyderabad and were evaluated in randomized block design with three replication. Principal component analysis (PCA) indicated that three components (PC1 to PC3) accounted for about 78.809% of the total variation among traits. Out of total principal components retained PC1, PC2 and PC3 with values of 58.125 %, 13.305 % and 7.380 % respectively contributed more to the total variation. The first principal component had high positive loading for 7 characters out of 18 viz.grain yield per plant (0.278), canopy temperature (0.278), 1000-grain weight (0.271), panicle length (0.270), critical temperature for reproductive stage (0.239), seedling vigour (0.213) and days to 50% flowering per plant (0.201) which contributed more to the diversity. Genotypes in cluster VI showed higher mean performance for most of the yield attributing characters. Therefore, selection of parents from this cluster for these traits would be effective. The result of present study could be exploited in planning and execution of future breeding programme in rice under aerobic condition.
