摘要

Little millet (Panicum sumatrense) is one of the C4, underutilized nutri-cereal crop belongs to Poaceae. It provides threefold security in terms of food, fodder and nutrition. It is rich in iron, vitamins and dietary fiber which can address the present issues of micronutrient malnutrition and diabetes. The present multi location evaluation was carried out with 35 genotypes to select stable high performers for yield, yield related and quality traits. WAASB biplots identified six high-yielding and stable genotypes, likewise for iron, zinc and protein content, six, eight and ten genotypes, respectively were identified as stable high performers. Further, WAASBY analysis with more weightage to trait performance compared to stability (70:30), recognized, VS 33 to be a better choice for grain yield, iron and zinc content. In addition, multi-trait selection for both performance and stability at 20% selection intensity through Multi Trait Stability Index (MTSI) selected LM 8400-17, GPUL 11, LM 4004, VS 19, OLM 18, VS 33 and VS 10 as best genotypes. It is very interesting to notice that, LM 4004 and OLM 18 were inferior for grain yield but were superior for other traits like early flowering, number of leaves per plant, flag leaf length, iron, zinc and copper content. The two genotypes can be used as parents in crossing programs. VS 33 and VS 10 were high-yielding as well as rich in iron and zinc content and hence can be further evaluated for the varietal development purpose.
