In the present investigation 92 Avena genotypes were evaluated for multi-cut nature in randomized block design with three replications at the Research Farm area of forage Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi season. Highly significant differences observed by analysis of variance showed presence of high amount of variability for single cut and multi-cut. Correlation analysis indicated positive and significant correlations of green fodder yield with dry matter yield, plant height and number of tillers. Genotypes collected from different geographical areas had a role in the clustering pattern and cluster with highest inter-cluster distances were considered for hybridization as potential parents for obtaining high heterotic response. In single cut, the principal component analysis found three components with eigen values more than one and altogether explained 67.95% of the total accumulated variability. The first principal component explained 26.24% followed by second (21.84%) and third (19.87%). of the total variance while principal factor-3 (PF-3) showed regarded as fodder yield factors. In second cut, seven principal components had eigen values more than one and altogether explained 73.34% of the total accumulated variability. The first principal component explained 15.31 % of the total variation, followed by second, third, fourth, fifth, sixth and seventh principal components explained 11.94, 11.79, 10.54, 10.40, 7.38 and 5.97 % of the total variance, respectively, while PF-2 and PF-4 regarded as fodder yield factors for second cut of multi-cut oat.
