Research Article


Iron and zinc malnourishment is consistent pan Asia–Pacific and Africa, as their intake and absorption is limiting. Breeding for high seed iron and zinc concentrations advocate to evaluate their association with various nutritional and anti-nutritional traits, which will assist in the selection process. Pigeonpea is a good source of protein and is being adopted widely as it can be grown on low-input, marginal lands. One hundred and four diversified genotypes of pigeonpea were scored for seven nutritional traits and significant differences were observed among them. The estimates of correlation coefficients and path analysis indicated that bolder seeds with high zinc concentration, lipid content and lesser contents of phytic acid should be aimed for enhancement of seed iron concentration, while, seed protein content can be used as a secondary variable for selection of this trait. On the other hand, small seeds with high lipid and iron concentrations and lesser contents of phytic acids and proteins should be targeted for improvement of seed zinc concentration in pigeonpea.
