Abstract
A research study for 50 accessions of little millet germplasm was carried out for DUS (Distinctness, Uniformity, and Stability) descriptors encompassing both qualitative and quantitative traits. The assessment adhered to guidelines from the International Union for the Protection of New Varieties of Plants (UPOV) and the Protection of Plant Varieties and Farmer's Rights Authority (PPV & FRA). The findings underscored substantial diversity among the germplasm accessions across all evaluated characteristics. This suggests a significant genetic diversity in the morphological profile of little millet germplasm. The outcomes of this study are valuable for breeders, researchers, and farmers in identifying and selecting germplasm accessions for crop enhancement. Additionally, they contribute to the conservation of beneficial genes and facilitate the pursuit of protection under the Protection of Plant Varieties and Farmer's Rights Act.
