Abstract

Evaluation of seventy rice genotypes during kharif 2004 with aromatic and non-aromatic lines showed significant differences among the genotypes. Correlation studies in scented and non-scented rice genotypes revealed that genotypic correlation coefficients were higher than phenotypic correlation coefficients for most of the characters under study. Character association analysis revealed significantly positive association of grain yield per plant with number of grains per panicle and 1000-grain weight. Path coefficient analysis revealed that 1000-grain weight, number of grains per panicle, productive tillers per plant, days to 50 per cent flowering, plant height have shown positive direct effects on grain yield, hence due weightage should be given to these characters during selection for future breeding programmes.
