 ABSTRACT

The present study was conducted with 44 oats genotypes using RCBD with three replications at Dryland Agriculture Research  Station, Budgam, Jammu & Kashmir and were grown during Kharif, 2017 to assess the  variability and diversity analysis using thirteen different yield and yield contributing characters viz., days to 50% flowering, plant height (cm), number of  tillers meter per row, inflorescence length (cm),flag leaf length (cm), culm diameter (mm), seeds per panicle (g), thousand seed weight (g), spikelet’s per panicle, green fodder yield quintal per hectare, grain yield quintal per hectare, seed yield per plant (g), number of leaves per plant. Analysis of variance revealed significant differences exists among the genotypes for all the characters studied. The estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were high for, grain yield quintal per hectare, culm diameter (mm), green fodder yield quintal per hectare, inflorescence length (cm), seeds per panicle (g), and seed yield per plant. High heritability coupled with high genetic advance were recorded for almost all the characters. D2 analysis was performed and clustering was done using Tocher’s Method. All the genotypes were grouped into 8 clusters. Cluster number I contained highest number (12) of genotypes and cluster II, VI, VII and VIII contained lowest number (1) of genotypes. Cluster V, IV, III and I showed maximum distance between them suggesting higher probability of heterotic hybrids if selection of parents is done from these pairs of groups. Green fodder yield, dry fodder yield, plant height and days to maturity showed highest contribution to total divergence. This study gave an insight into the variability pattern of the advanced oat lines which will be helpful in their further utilisation.

Key words: Oat, Advanced lines, Diversity, Variability, Cluster analysis.
