Abstract ABSTRACT French bean is one of the main sources of protein, dietary fibers and minerals in diet, occupying very important role in human health. It is a good source of minerals, such as iron, zinc and other micronutrients compared to cereals or root crops. The deficiency of micronutrients is a global health problem, which is due to inadequate intake of balance diet. Realizing the importance of micronutrients for human health, there are several approaches undertaken by researchers to enhance its contents in grain legumes. Biofortification is seen as an upcoming strategy for dealing with micronutrient deficiency in world. Common bean are a staple food crop and sources of protein and rich content of minerals especially Fe and Zn, thus the present study was carried out to screen twenty four accessions for micronutrients Fe, Zn, Mn and Cu content. The studies revealed that the accessions IC342273 and EC53 I 078 showed significantly higher pod yield and seed yield. Further the accession IC538420 ( 177.31 ppm) exhibited significantly higher mean Fe and accession EC500226 showed significantly higher Zn (26.91 ppm), Mn ( 15.31 ppm) and Cu (8.55 ppm) content over other accessions and varieties. The above twenty four accessions were screened using SSR markers linked to Fe and Zn content, twelve SSR primers amplified, the two genomic SSR markers BM 154 and BM2 I I exhibited higher polymorphism among the accessions used for screening of micronutrient content. The above SSR markers can be used in future crop improvement programmes involving biofortification of French bean for micronutrients content.
