- Abstract
The current study was conducted based on the morphological, biochemical, and SSR characterization of wild Oat (Avena fatua L.) genotypes collected from three different Districts of Malakand Division, Pakistan. A significant variance was observed across all twenty morphological parameters, indicating a high likelihood that breeding programs would introduce fresh variety into adapted oat cultivars. A substantial variation was also found for leaf length (32.55%) and stem diameter (28.33%), as compared to the number of spikelet (15.66%). The harvest index and plant height had a high and positive correlation (0.79**), while a negative correlation (-0.76**) was observed for plant height and plant biomass. All genotypes were arranged into three groups based on the cluster analysis, each having a Euclidian distance of 87%. A total of 15 bands were visible for the total seed storage proteins, out of which 10 were polymorphic and 5 were monomorphic. The entire dataset of 54 oat genotypes was split into 2 lineages (L-1 and L-2) based on two-way cluster analysis, with a genetic distance of 36.5% between them and further subdivided into three subgroups at 60% genetic distance. The SSR markers used in this study successfully amplified genomic regions from oat genotypes. Out of 5 SSRs, HVM62 showed the prominent polymorphism, and among eight alleles detected, two were monomorphic and six were polymorphic. Z48431 had the highest PIC value (0.93), followed by HVM62 (0.89). Band-14 had the highest PIC value at 0.90%, followed by bands 9 and 10 (0.80% and 0.50%, respectively). Bands 8, 11, 12, and 13 had the lowest PIC value, correspondingly. The overall findings showed a significant degree of variety in the oat genotypes growing in District Swat and Dir, which offers the potential for the introduction of distinctive diversity in well-adapted oat cultivars.
