Abstract: Cowpea seed coat colour is one of the important consumer traits of the crop in West Africa. The objective of the study was to find out the ratios of different seed coat colour types that would segregate from crosses involving cowpea genotypes of different colours. This would enable breeders to anticipate seed coat colours that would result in segregating populations and also help in estimating the number of genes controlling the trait. Six different bi-parental crosses were made and the resulting seeds grown to F1 plants. Seeds were harvested from F1 plants and grown on the field. An average of 250 plants was studied within each segregating population. The number of seed coat colour phenotypes produced varied from two for Bambey 21/Gbode to ten for Bambey 21/Tona. Individuals of some of the populations could not be classified based on seed coat colour as they exhibited continuous variation and therefore Chi-square goodness of fit test could not be conducted on them. It is suspected that many genes might be involved in seed coat colour inheritance in cowpea and as such the use of molecular and quantitative principles may be helpful in understanding the genetic control of the trait.
