SUMMARY
Correlation and path analysis for grain and fodder production in oats (Avena sativa L.) were studied
for 30 genotypes of oats. Correlation of grain yield was positive and significant at phenotypic and genotypic levels with characters viz., plant height, tillers per metre row length, dry matter yield (q/ha), seed index, straw yield (q/ha) and green fodder yield (q/ha). Path analysis revealed that direct effect of seed index, dry matter yield (q/ha) and plant height were of high magnitude. The high positive association of other characters with grain yield per plant (g) was also due to high indirect effect through these characters. This indicated that grain yield was mainly a product of direct and indirect effects of seed index, dry matter yield (q/ha) and plant height. The high positive association of other characters with green fodder yield (q/ha) was also due to high indirect effect through dry matter yield (q/ha) and plant height. This indicated that green fodder yield was mainly a product of direct and indirect effects of dry matter yield (q/ha) and plant height.
