Cowpea is cultivated on more than 11 million hectares with a worldwide productionof 5.4 million tons of dried seeds. Cowpea is an affordable source of protein, which isused as an alternative to soybean for people who are allergic to soybean protein. Theaim of this research was to assess the variability of the total seed protein content incowpea. Eleven Arkansas breeding lines were used in this study. Field experimentdesign was a randomized complete block design RCBD with 2 blocks, and conductedin three different locations within Arkansas State Fayetteville, Alma, andHope in 2015. A standard chemical protocol was performed involving an analysis ofthe total nitrogen by combustion using an Elementar Rapid N III instrument to estimatethe protein content. The average protein content was 25.4%, and ranged from23.7% to 27.4% with a standard deviation of 1.9%. The significant effects of genotype,environment location, and genotype by environment were observed for the totalseed protein content in cowpea. The broad sense heritability H2 for cowpea seedprotein was estimated to be 57.8% based on the eleven cowpea genotypes studied.The cowpea lines -Early Scarlet- and 09-204 had the highest seed protein contentwith 27.4% and 26.9% dried seed weight, respectively. This study provides valuableinformation on cowpea protein content for breeders to select and utilize thosebreeding lines with high seed protein content to develop new high protein cowpeacultivars.
