摘要

Oats, a promising crop for Himalayan agroecologies, have recently gained traction in the Union Territory of Jammu & Kashmir, significantly enhancing economic prospects for small-scale and marginal farmers. However, in neighbouring Himalayan states like Uttarakhand and Himachal Pradesh, adoption remains limited despite available cultivars and sustained research efforts. This disparity underscores the need for region-specific breeding programs tailored to climatic variability and farmer preferences, particularly in Himalayan regions with sharp agroecological gradients. Improving crops for economically significant traits requires an understanding of the principles governing genetic variability. This paper analyzes a wide range of exotic oat germplasm to understand the extent of variability and identify specific genotypes suitable for oat breeding programs. The primary objective was to assess the genetic variability of agronomic and quantitative traits in diverse germplasm lines of exotic oats in the Northwestern Himalayan region. The material underwent assessment via an augmented block design incorporating five checks across two distinct locations: SKUAST-K, DARS Budgam, and SKUAST K Wadura, spanning 2019 and 2020. Principal Component Analysis and Euclidean clustering were conducted to analyze the germplasm diversity patterns. Significant morphological variability was observed, with yield traits showing the highest genetic advance. A favorable negative correlation between green NDF and fodder yield highlights opportunities for forage improvement. Multivariate analysis identified key genotypes for region-specific breeding programs. The present research revealed intriguing results on the variability and trait diversity in the oat germplasm grown in the North Western Himalayan region. A successful breeding plan for the enhancement and selection of forage oats may be developed by utilizing the data on variability and diversity characteristics.
