dc.titleCharacterization of cowpea cultivars for grain size, color, and biofortificationen
dcterms.abstractCowpea crops have high socioeconomic importance in the Northeast region of Brazil. These crops generate employment and income; in addition, it is an excellent source of protein, minerals, vitamins, and dietary fiber, and contributes to the food security of thousands of people. Biofortification of cowpea with iron, zinc, and proteins can contribute to prevent the higher hunger. The objective of this work was to assess iron, zinc, and protein contents in cowpea grains of different cultivars and the effect of grain size and color on the contents of these nutrients. Twenty-four cultivars with variation in size and color of the seed coat were evaluated. Iron contents ranged from 7.12 to 8.60 mg 100 g-1, with an overall mean of 7.75 mg 100 g-1. Zinc contents ranged from 4.46 to 4.93 mg 100 g-1, with an overall mean of 4.71 mg 100 g-1. Protein contents ranged from 31.50 to 36.24 g 100 g-1, with an overall mean of 33.57 g 100 g-1. Grain size ranged from 13.55 to 37.88 g, with an overall mean of 21.50 g. The cultivars Caldeirão, BRS-Guariba, and Pingo-de-Ouro-1-2 have higher iron contents; BRS-Aracê and BRS-Imponente have higher zinc contents; BR-14-Mulato, BRS-Guariba, BRS-Aracê, and BRS-Inhuma, have higher protein contents; and BR-3-Tracuateua and BRS-Imponente have larger grain sizes. The size and color of the seed coat do not influence the iron, zinc and protein contents of the evaluated cowpea cultivars.en
