 ABSTRACT

A trial was conducted to Studies on heterosis and transgressive segregants for fodder and grain related traits in Oat (Avena sativa  L. ) in a diallel cross set  8  parents, 28 F1 S and 28 F2 S  oat were evaluated in randomized complete block design with three replications. The aim of correlation coefficient study is to find out the statistical measurement used to find out the degree and direction of the relationship between two or more variables. The characters plant height, tillers per plant, leaves per plant, leaf length, leaf width, dry matter yield, seed per panicle, harvest index, mean groat mass and green area index have positive and significant correlation with grain yield per plant in F1 generation while in F2 generation, days to 50 % flowering, days to maturity, plant height, tillers per plant, spike length, leaves per plant, leaf width, seed per panicle, harvest index, hecto lit. grain weight, mean groat mass and groat length have positive and significant correlation with grain yield per plant.
The maximum inter-cluster distance value was recorded between cluster VI and cluster VII in F1 generation and in F2 generation maximum inter cluster distance was recorded between cluster I and cluster V. The maximum intra cluster distance was found for cluster VI in F1 generation while in F2 generation the maximum intra cluster distance was found for cluster VI. Based on maximum inter cluster distance between cluster VI and cluster VII in F1 generation while in F2 generation I and V, superior genotypes of cluster VI may be used as parent with superior genotypes selected from cluster VII in hybridization programme for creation of variability followed by selection for desirable recombination’s in segregating generation. As cluster VI had highest intra cluster distance indicated divergence among the genotypes of this cluster. Therefore, genotypes of this cluster might be used for hybridization programme considering the mean performance of genotypes for major yield attributing traits.

Key words: Correlation co-efficient, Genetic divergence.
