| description | Pigeonpea (<i>Cajanus cajan</i>) is an important grain legume that provides highly nutritious food for human consumption. It contains high amounts of protein, carbohydrates, fats as well as both macro- and micronutrients. This study examined the genetic diversity of grain mineral and protein content among fourteen pigeonpea landraces. There were highly significant differences (<i>p</i> ≤ 0.001) among the landraces for most of the mineral elements including calcium (Ca), copper (Cu), potassium (K), magnesium (Mg), manganese (Mn), phosphorus (P) and zinc (Zn). The K and P content ranged from 8874.21 to 15,817.38 mg/kg and 2899.23 to 4945.12 mg/kg, respectively. Relatively high amounts of Ca (2103.43 mg/kg) and Mn (73.11 mg/kg) were observed in ‘G-03’, but ‘G-09’ attained the highest content of K (15,817.38 mg/kg) and Zn (38.56 mg/kg). Highly significant (<i>p</i> ≤ 0.001) negative correlations were observed between Mn and Cu. The principal component analysis showed that three landraces (‘G-03’, ‘G-04’ and ‘G-05’) were highly associated with Ca, P, Mg and Mn. The three landraces (‘G-03’ for Ca and Mn; ‘G-04’ for Mg and P; ‘G-09’ for Cu, K and Zn) possessing high grain mineral and protein (‘G-10’) contents can be utilized in pigeonpea breeding programs that are aimed at improving the grain’s traits. |
