Little millet (Panicum sumatrense Roth. Ex. Roem. & Schult.), a member of the grass family Poaceae, is native to India. It is nutritionally superior to major cereals, grows well on marginal lands, and can withstand drought and waterlogging conditions. Two-hundred diverse little millet landraces were characterized to assess variability for agronomic and nutritional traits and identify promising accessions. Highly significant variability was found for all the agronomic and grain nutrient traits. Accessions of robusta were high yielding whereas those of nana were rich in grain nutrients. About 80% of the accessions showed consistent protein and zinc (Zn) contents whereas iron (Fe) and calcium (Ca) contents were less consistent (29.5 and 63.5%, respectively) over 2 yr. Promising trait-specific accessions were identified for greater seed weight (10 accessions), high grain yield (15), high biomass yield (15), and consistently high grain nutrients (30) over 2 yr (R² = .69–.74, P ≤ .0001). A few accessions showed consistently high for two or more nutrients (IPmr 449 for Fe, Zn, Ca, and protein; IPmr 981 for Zn and protein). Five accessions (IPmr 855, 974, 877, 897, 767) were high yielding and also rich in Ca. Consumption of 100 g of little millet grains can potentially contribute to the recommended dietary allowance of up to 28% Fe, 37% Zn, and 27% protein. Multilocation evaluation of the promising accessions across different soil types, fertility levels, and climatic conditions would help to identify valuable accessions for direct release as a cultivar or use in little millet improvement.

小小米（Panicum sumatrense Roth. Ex. Roem. & Schult.）种质中谷物产量和营养性状的变异性和性状特异性种质

小粟（Panicum sumatrense Roth. Ex. Roem. & Schult.）是禾本科禾本科的一员，原产于印度。它在营养上优于主要谷物，在边缘土地上生长良好，并且可以抵御干旱和内涝条件。对 200 种不同的小小米地方品种进行了表征，以评估农艺和营养性状的变异性，并确定有希望的种质。发现所有农艺性状和谷物营养性状都存在高度显着的变异性。的种质罗布斯塔是高产而那些的娜娜含有丰富的谷物营养。在 2 年内，大约 80% 的种质显示出一致的蛋白质和锌 (Zn) 含量，而铁 (Fe) 和钙 (Ca) 含量不太一致（分别为 29.5% 和 63.5%）。确定了具有较大种子重量（10 种）、高谷物产量（15）、高生物量产量（15）和持续高谷物养分（30）超过 2 年（R ² = .69–.74 ）的有希望的性状特定种质, P≤ .0001）。一些种质显示两种或多种营养物质的含量始终很高（铁、锌、钙和蛋白质的 IPmr 449；锌和蛋白质的 IPmr 981）。五个种质（IPmr 855、974、877、897、767）高产且富含钙。食用 100 克小小米谷物可能有助于达到推荐的膳食摄入量，即高达 28% 的铁、37% 的锌和 27% 的蛋白质。对不同土壤类型、肥力水平和气候条件的有希望的种质进行多地点评估将有助于确定可作为栽培品种直接释放或用于小小米改良的有价值的种质。
