Abstract:

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. Analysis of variance for individual environment for grain nutrient content revealed highly significant differences among the genotypes. Genotypes JWM-1 and VR-1034 for calcium content; OUAT-2, TNEC-1234 and GPU-71 for iron content and OUAT-2, TNEC-1234, VR-1034, GPU-71 and VR-936 for zinc content were identified. Pooled analysis of variance showed significant genotype × environment effects were observed for grain Calcium, iron and zinc contents. Eberhart and Russel stability parameters indicated the genotypes OUAT-2, VR-1034, GPU-71, GE-728 and JWM-1 were consistently adapted across the environments whereas, TNEC-1234, VR-936, GE-6834-1, VL-384, WFM-10, KMR-344, DHWFM 11-3, DHWFM 2-3 and GPU-67 were poorly adapted across the environments for their grain calcium content. Genotypes VR-1034, GPU-71, DHWFM 11-3, OUAT-2 and JWM-1were consistently stable across the environments whereas VR-936, GE-728, GE-6834-1, WFM-10, KMR-344, DHWFM 2-3 and GPU-67 were poorly adapted across the environments for their grain iron content. The genotypes TNEC-1234, VR-936, and GPU-71 were consistently stable whereas OUAT-2, GE-728, GE-6834-1, VL-384, JWM-1, KMR-344, DHWFM 2-3, GPU-67 poorly stable across the environment for their grain zinc content. It is observed that genotype GPU-71 is stable for iron, calcium and zinc contents across the two locations and two years. This genotype could be used as a parent for hybridization to improve micronutrient content.
