Abstract: Character association and path coefficient analysis among grain yield, yield components and nutritional traits were studied in 38 genotypes of rice. Analysis of variance revealed the existence of significant differences among genotypes for all the 17 characters studied. Grain yield per plant was positively and significantly associated with harvest index, panicle weight, number of productive tillers per plant, panicle length, number of filled spikelets per panicle, kernel length, SPAD chlorophyll meter reading, kernel L/B ratio and 1000 grain weight indicating that simultaneous improvement of all the characters is possible. Path coefficient analysis indicated that highest direct effects on grain yield in the traits viz., days to 50 per cent flowering, 1000 grain weight, kernel L/B ratio, number of filled spikelets per panicle, harvest index, plant height, kernel breadth, SCMR, iron and protein content. Hence emphasis can be laid out on these traits during selection for further improvement in grain yield in rice.
