Abstract:
The present experiment was conducted at Forage Section Department of Genetics & Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar with 92 genotypes collected from different eco-geographical regions during rabi 2015-16to estimate the magnitude of correlation among yield and quality traits and their effects in multi-cut Oat.
In 1st cut of multi-cut, positive and significant correlations of dry matter yield per meter row length were recorded for plant height, number of tillers per plant and green fodder yield at genotypic as well as phenotypic level while in 2nd cut plant height, number of tillers per plant, germination percentage, seed vigour index-I and green fodder yield had positive and highly significant correlation at genotypic as well as phenotypic level with dry matter yield. Path coefficient analysis in 1st cut revealed positive and direct effect of green fodder yield (0.8902) and yield contributing traits viz., tillers per plant (0.1518), plant height (0.1401), germination percentage (0.3403), seedling length (0.9877), seedling dry weight (0.4166), seedling vigour index-I (0.8125) and seedling vigour index-II (0.3148) while crude protein (-0.1341) had negative direct effects on dry matter yield per plant. Whereas, in 2nd cut positive and high direct effects of green fodder yield (0.9164), tillers per plant (0.2341) and plant height (0.1401), while days to 50% flowering (-0.089), length (-0.0769), axis length (-0.0945), and number of leaves per plant (-0.1473) had negative direct effects on dry matter yield per plant.
Therefore, it would be better to emphasize on characters viz. green fodder yield, number of tillers per plant and plant height in 1st and 2nd cut and seed yield per meter row length can be used in 2nd cut for the improvement of dry matter yield.
