Abstract:

rown cereal crops. It is widely cultivated for forage purposes because of its high regenerating capability. Oat grain has tremendous health benefits. Therefore the study of variability and correlation among yield contributing traits becomes important. Keeping this in view, in the present research sixteen morphological traits were studied for fifty six diverse oat genotypes. The experiment was conducted in RCBD design during Rabi 2017-2018. Significant variation was seen for all the traits under study. High GCV and PCV were seen for most of the most of traits except plant height, days to 50% flowering, days to maturity. High heritability coupled with high genetic advance was observed for most of the characters viz., flag leaf length, leaf length, leaf width, leaf stem ratio, internode length, number of tillers plant-1, peduncle length, axis length, number of spikelets plant-1, seed yield plant-1, 100-seed weight, green fodder plant-1 and dry fodder plant-1. Genotypes namely HFO878, HFO-614, HFO-879 and HFO-707 showed good performance for both seed yield as well as green fodder yield. A study of variability, genetic advance, heritability and correlation will provide an opportunity for fruitful selection of the genotypes based on traits with high genetic advance and heritability and showing positive significant correlation with economic yield. Among the different traits which showed positive significant correlation with seed yield and green fodder yield, interestingly tillers plant-1 showed positive significant correlation both.
