Genotypic variation for seed protein and mineral content among post-rainy season-grown sorghum genotypes

---

Sorghum is an important staple food crop of Asian and African countries. As a “poor man's crop”, it provides dietary starch, protein, and some vitamins and minerals. Minerals are important for various physiological functions in the human body. As a major staple crop of central and southern Indian provinces, sorghum landraces are a source of supplementary micronutrients. Concentrations of micronutrients and protein and yield parameters were studied using 112 local landraces and varieties. Univariate analysis revealed wide variation for iron (1.10–9.54 mg 100 g−1), zinc (1.12–7.58 mg 100 g−1), protein (3.50–12.60%), and grain yield (2.50–76.50 g) among the landraces. High estimates of genetic/phenotypic coefficient of variation, and genetic advances over the mean were identified for landraces and
varieties. High heritabilities were also identified for yield and mineral content. Correlation estimates among the genotypes indicated that grain yield was positively correlated with copper and protein with copper and zinc. Cluster analysis based on Euclidean distance resolved all of the genotypes into three major clusters. The wide range of values with high heritability estimates may favor the use of these landraces in recombination breeding to improve nutritional quality in sorghum.
