Selecting orange-fleshed sweet potato genotypes using selection indices

ABSTRACT Vitamin A deficiency is common in developing countries. Sweet potato can be an ally reversing this situation since it has a low acquisition cost and high market availability. In addition, some genotypes have orange-flesh roots, rich beta-carotene, which the precursor of vitamin A. Thus, objective research was to select orange-fleshed sweet using two selection indices (Smith Hazel Mulamba & Mock). For purpose, seven half-sibling families with orange flesh roots (141 experimental commercial cultivar Beauregard) were evaluated, assessing yield-related traits, external appearance pulp color intensity, susceptibility Euscepes postfasciatus. The UZBD-C-14, UZBD-U1-25, UZBD-F-15, UZBD-C-30, UZBD-K-32, UZBD-U1-10, UZBD-L2-14, UZBD-L5-67 most promising, showing greater balance for evaluated characters. Furthermore, these are suitable new studies confirm their productive performance root quality evaluate biochemical parameters that prove inheritance character regulating biofortification mediated by carotenes.
