RESUMO
In India, where cereal-based meals make up the majority of the daily diet, bread wheat (Triticum aestivum L.) is a key grain crop. Micronutrient deficiencies are a result of the lack of a diverse food culture in the nation. Genotypes of bread wheat that have been biofortified might be introduced to address this. It is anticipated that more information on the genotype x year interaction of these nutrients in grain will help us better understand the size of this interaction and perhaps even identify more stable genotypes for this attribute. Year revealed divergent responses to grain iron and zinc. Compared to zinc, iron showed lowest variation across year. Maximum temperature was the major determinant for the four traits. Iron is also significant correlation with zinc. Among the total fifty-two genotype, HP-06, HP-22, HP-24, HP-25, HP-33, HP-44, and HP-45 were found superior for zinc and iron content. These genotypes with high levels of zinc and iron can be used in a hybridization programme to further crop improvement. Wide-scale cultivation of the chosen genotype with high zinc and iron content in the agro-climatic conditions of Jammu will work with the region's current cropping systems.
