SUMMARY
The present study was conducted with 25 exotic germplasm accessions along with three
checks at Forage Research Farm, Department of Plant Breeding and Genetics, Punjab Agricultural
University, Ludhiana during Rabi season 2019-2020. The objective of the study was to determine
the extent of correlation among green fodder yield with contributing traits and their effects. The high value of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was observed for number of leaves followed by green fodder yield and number of tillers. High heritability was estimated for percent crude protein content (99.68%), number of leaves (97.84%) and acid detergent fiber (97.09%). Higher genetic advance was observed for number of leaves (98.70%) and green fodder yield (79.38%). Traits like plant height (0.533), leaf length (0.416) and leaf width (0.292) had positive and significant correlation with green fodder yield. Positive and direct effect of plant height (0.942) and number of leaves (0.218) on green fodder yield. The results suggest that traits like plant height, leaf length and leaf width are the main fodder yield components. So, selection for these traits should be practised in future breeding programme for improving the green fodder yield in oats.
