Abstract

The present investigation was undertaken with the objective to study correlation between various yield and yield attributing traits among the 188 RIL population developed from the cross between ICPL 20097 and ICP 8863 (maruti). Field experiments to study 14 important agronomic traits were carried out at two locations ARS, Tandur and College farm, PJTSAU during Kharif 2012 and 2013 at Tandur and Kharif 2013 at PJTSAU, respectively. Pooled analysis of data from all the locations showed a total of 91 pair wise combinations among the fourteen traits studied, of which 31 combinations were found to be significantly correlated. Yield per plant showed positive significant correlation with pods per plant at across the environments and within all the individual environment and positive correlation with pod weight, plant height and secondary branches at across the environments. Thus, improvement of yield per plant can be achieved by direct selection through these significantly positively associated characters.
