Genetic variability, association of characters and path coefficient analysis of saline and alkaline rice genotypes under rained condition

摘要

In any crop improvement programme, variability present in a population and the extent to which it is hertiable are important factors to have effective selection. Yield being a complex character is composed of several components, some of which affectthe yield directly while others contribute towards it indirectly. Correlation studies provide an opportunity to study the magnitude and direction of association of yield with its direct and indirect components and also among various components. Correlation and path analysis thus help in identifying suitable selection criteria for improving the yield. Considering these points in view, the present study was conducted to understand interrelationship of the economic traits in upland rice in sandy, alkalinecondition.
