Stability of grain nutrient concentrations in white finger millet

Grain calcium, iron and zinc are important micronutrients for human health for which deficiency occurs widespread in the world. Knowledge on genotype × environment interaction of these nutrients in the grains is expected to contribute to better understand the magnitude of this interaction and the potential identification of stable genotypes for these traits. The present investigation was carried out during kharif 2013 and 2014 in the experimental farm of Zonal Agricultural Research Station (ZARS), Bengaluru and ZARS V. C Farm Mandya to identify stable genotypes southern dry zone. The fourteen genotypes were evaluated at two locations to assess the genetic variability, detect genotype ×environment interaction and identification of genotypes which are stable across the two locations for grain nutrient content.
