Abstract

Rice is most important food crop of India and grown in different regions with differential consumer preferences for grain size, shape, aroma and cooking qualities. Therefore, crop improvement in rice not only focused on yield but also to enhance quality. Hence the present investigation was carried out with an objective of assessing the character association among twenty-two morphological and quality characters of thirty basmati rice (Oryza sativa L) genotypes. Correlation analysis revealed that Seed yield was significantly and positively associated with days to maturity (0.330**), number of tillers per plant (0.434**), number of grains per panicle (0.358**), grain weight per panicle (0.410**), and flag leaf length (0.258*).  The days to maturity exhibited a significant positive correlation with plant height, panicle length, grain weight per plant, kernel length before cooking, kernel length after cooking and L: B ratio. Tiller per plant reflected the positive and significant association with a number of grains per panicle, grain weight per panicle and grain weight per plant. Flag leaf length showed a significant positive correlation with a number of grains per panicle and grain weight per plant, while Grains per panicle was positively and significantly associated with grain weight per panicle, grain weight per plant and kernel breadth before cooking.  Grain weight per panicle exhibited a significant positive association with grain yield per plant (0.410**), kernel breadth before cooking (0.381**), 100 grain weight (0.240*) and 100 kernel weight (0.210*).  These characters could be utilized to form a selection index for improvement of the basmati rice.
