Twenty yellow-, red- and purple-kernel maize accessions were collected from three geographic regions in Ghana for the study. The objective was to determine the presence of opaque -2 gene and ï¢-carotene content of the grains as a means of assessing nutritional quality. Variability in ï¢-carotene content was determined by HPLC while presence of opaque 2-gene was determined by a light box. Significant variations were found...
