The study was conducted among the thirty two rice varieties of the Breeders Seed Production chain of Tamil Nadu during Kharif 2016-17. Days to 50 per cent flowering, plant height, leaf length, number of panicles per plant, panicle length, number of grains per panicle, 1000 grain weight, time to maturity and single plant yield showed significant difference between varieties. Correlation study showed significant positive correlation on single plant yield by leaf length, leaf width, number of panicles per plant, number of grains per panicle, 1000 grain weight and time to maturity. Path analysis for direct and indirect effects on yield revealed significant high direct effects for number of panicles per plant, number of grains per panicle, 1000 grain weight, days to 50 percent flowering and time to maturity. Number of grains per panicle via number of panicles per plant showed significant high association on single plant yield.
