Abstract

Wheat germplasm is a key factor in sustainable wheat breeding programme. Increasing the amount of bioavailable mineral elements like iron and zinc in wheat would help to improve the nutritional status of populations in developing countries like India. It is important to have information on genetic variations among different wheat landraces by which plant breeding programs can use new varieties in cross-breeding programs. In this study, estimation of iron and zinc in 180 wheat landraces was performed in duplicate using an Oxford Instruments Xâ�?Supreme 8000 based on technique of Xâ�?ray fluorescence analysis (XRF). Material for the study was obtained from National Beuro of Plant Genetic Resourses, Delhi, India. The results showed that the iron and zinc distribution ranges of Indian wheat landraces are 33 mg/kg to 51mg/kg and 30 mg/kg to 67 mg/kg respectively. The landraces with the highest iron content, 51 mg/kg have zinc 56 mg/kg and the landrace with the highest zinc content 67 mg/kg, showed iron concentration of 50 mg/kg. Iron, zinc-rich genotypes identified from this study opens up the possibilities for the identification of genomic regions responsible for mineral uptake and translocation that can be used as donor for developing nutrient enriched varieties.
