SUMMARY
The present investigation was carried out in Forage Section Department of Genetics & Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar during rabi 2015-16 to estimate the magnitude of correlation among yield and quality traits and their effects. Positive and significant correlations of dry matter yield per meter row length were recorded for plant height, seed yield per meter row length, green fodder yield per meter row length, flag leaf length, inter-node length, axis length, leaf length and germination %. Path coefficient analysis revealed that characters viz. green fodder yield, number of tillers per plant, plant height and seed yield per meter row length had positive and direct effects on dry matter yield per meter row length, while the characters number of days to 50% flowering, peduncle length, axis length, number of spikelets/panicle, and number of leaves per plant showed direct negative effects. Hence, it would be rewarding to lay stress on characters viz. green fodder yield, number of tillers per plant, plant height and seed yield per meter row length for the improvement of dry matter yield.
Key words: correlation, Avena sativa L., selection, fodder
