Abstract

In the present study 35 coloured rice genotypes along with three checks were evaluated in Randomized Complete Block Design for yield, nutritional and cooking quality traits to study association between the yield, nutritional and cooking quality traits. Correlation studies showed positive and significant correlation of grain yield per plant with yield contributing characters like ear bearing tillers per plant, panicle length, test weight, number of filled grains per panicle and some nutritional characters like protein content and anthocyanin content. The path analysis revealed that traits like ear bearing tillers per panicle, test weight, number of filled grains per panicle, alkali spreading value and anthocyanin content showed not only positive direct effect but also positive correlation with grain yield suggesting the importance of direct selection for above characters. The residual effect in the present study was 0.3696 and 0.2348 at phenotypic and genotypic levels respectively, indicating that the characters included in the present study clearly explained the direct and indirect effects on the dependent variable to some extent.
