SUMMARY
The study was conducted to investigate the correlation coefficient and path coefficient in relation to fodder yield and other yield attributing traits. Correlation studies revealed that, both at genotypic and phenotypic levels, significant positive correlation of green forage yield was observed for days to 50 per cent flowering, plant height, leaf breadth, leaf area per plant, leaves per plant, leaf-stem ratio, primary branches per plant, length of primary roots, root volume per plant and dry matter yield. Path analysis showed that, dry matter yield showed the highest and positive direct effect on green forage yield. Leaf area per plant and primary branches per plant had negative direct effect on green forage yield.
Key words:Correlation coefficient, path coefficient, green forage yield, ricebean
