Evaluation of rice genotypes for utilization in rice improvement programme in northern region of Bihar
Abstract
Selection of germplasm /genotypes based on visual observation for different polygenic traits is less rewarding. In this context, selection of superior rice genotypes by assigning ranks to each genotype for various quantitative traits followed by rank correlation was estimated and it was observed that two multiple regression equation involving eight and four quantitative traits exhibited similar efficiency, indicated that four characters viz. panicle length, number of primary branches, L/B ratio and 1000 grain weight were the best characters for formulating selection criteria. Top ten genotypes identified on the basis of selection score were TCA-88-1, TCA88-3, TCA88-2, TCA88-81-1, TCA88-57-3, TCA88-10-1, TCA88-13-2, TCA88-79-2, TCA88-22 and TCA88-44-1. These genotypes found to be suitable for grain yield and components traits may be selected for further evaluation and utilization in rice improvement programme of north Bihar condition.
