Polymorphism and Iron and Zinc Contents in Fababean Genotypes

Twenty seven fababean genotypes acquired from different agroclimatic regions of India were evaluated for iron and zinc content and genetic diversity using RAPD markers. The number of pods/plant, number of seeds/pod and 100 seed weight, iron and zinc content in the genotypes ranged from 14–46, 2.8–3.6, 20.4–28.3, 2.47–4.19 mg/100g and 2.55–4.90 mg/100g, respectively. The genotypes analyzed for their genetic diversity and relationship using RAPD primers showed polymorphism and polymorphic information content and resolving power varied from 0.61 to 0.88 and 0.88–6.66, respectively. Cluster analysis based on mineral content and genetic diversity showed that the genotypes HB184 and HB186 as well as PRT12 and RFB5 showed close relationship both through molecular and nutritional analysis.
