Abstract:
Rice is a staple food for more than half of the world’s population, but the production is severely affected by the impact of abiotic stresses due to frequent change in climate. Hence there is a need to combine desirable traits of different varieties using Multi-parent advanced generation inter-cross population (Magic) and identify high yielding rice genotypes suited to varied topographic regions. The present investigation was carried out at ZAHRS, Shivamogga by using multi-parent advanced breeding lines of the MF₆ generation developed by crossing eight diverse varieties having desirable traits. The variability studies among the lines revealed a higher GCV, PCV, heritability and genetic advance as per cent of mean for majority of yield attributing traits. The correlation and path coefficient studies on yield and its contributing traits revealed majority of the traits were positively associated with yield.
