摘要

Foxtail millet is an excellent source of protein, micronutrients and dietary fibers which can be successfully exploited in the changing climatic conditions. To harness this potential, in the present study a panel of 209 diverse foxtail millet accessions from 22 countries was evaluated for agro-morphological and yield traits under the western Himalayan conditions, a potential set of genotypes were selected and profiled for nutritional traits. The analysis of variance showed huge genetic variation for the yield related traits. Diversity analysis revealed three clusters that provides critical insights for identifying best adapted genotypes in this environment; nearly 100 genotypes were having higher grain yield than the mean value. The principal component analysis (PCA) showed that the first two principal components accounted for 74.0% of the total variation. Among the diverse panel of 209 entries, 20 potential genotypes were selected for the nutritional profiling; disclosed significant variation in all studied agro-morphological and nutritional traits. Based on mean performance six genotypes FM83, FM34, FM32, FM42, FM232, and FM4 were identified as high-yielding. The higher protein, crude fiber and mineral content with comparatively lesser anti-nutients were present in FM156, FM92, FM144, and FM4. The phytate/mineral molar ratios suggested that the bioavailability of these minerals were poor and would be a concern to take up in future improvement programs. The heatmap showed that the fourth group has better performance for the nutritional traits and lesser anti-nutrient contents. The genotypes from this group can be used in future improvement programs because of their elite nutritional properties and for better yield under western Himalayan conditions. Overall, this work contributes to identifying high-quality foxtail millet genotypes capable of enhancing regional nutrition security and supporting long-term dietary health.
