Mapping of AFLP loci linked to tolerance to cowpea golden mosaic virus

M. A. Rodrigues, Santos, C. A. F., and Santana, J. R. F., Mapping of AFLP loci linked to tolerance to cowpea golden mosaic virus, vol. 11, pp. 3789-3797, 2012.

AFLP markers combined with the bulk segregant analysis methodology was used for the identification of molecular markers associated with the cowpea golden mosaic virus (CGMV) resistance gene in 286 F2 cowpea plants derived from the cross IT97K-499-35 x Canapu T16. Segregation data in the F2 population demonstrated that tolerance to CGMV is controlled by a single dominant gene.

Breeding biofortified cowpea lines for semi-arid tropical areas by combining higher seed protein and mineral levels

C. A. F. Santos and Boiteux, L. S., Breeding biofortified cowpea lines for semi-arid tropical areas by combining higher seed protein and mineral levels, vol. 12, pp. 6782-6789, 2013.

One strategy to mitigate human malnutrition in semi-arid areas is to increase the protein and mineral content of cowpea cultivars. Total seed protein, potassium, calcium, iron, zinc, and sodium contents were quantified in elite cowpea lines, with the aim to develop cultivars that had improved levels of these nutrients. Eighty-seven F6 lines derived from 6 crosses were evaluated under rain-fed conditions in Petrolina, Brazil. Seed protein and mineral content were quantified by the micro-Kjeldhal method and in an atomic absorption spectrophotometer, respectively.
