"Setentão" uma nova cultivar de feijão-de-corda para o estado do Ceará

A cultivar of cowpea, Vigna unguiculata, named "Setentão" was obtained from a cross between "Sempre Verde" with seeds with cream integument and "TVu 59" with seeds with brown integument. The genealogical method with productive capacity test was used in the selection for F3 and F4 generations, with the best lines submitted to a bulk selection in isolated blocks (with lines separated by maige) in the F5 generation. Individual selection was carried out within each line and the assay productions with 14 lines were initiated at the F7. The selected line 010.061 (05) (01) (03) presented excellent seed quality together with good productive capacity and resistance to cowpea severe mosaic virus and cucumber mosaic virus isolated in Ceará from cowpea. The selected line named "Setentão" has indeterminate growth with semi-climbing habit and good productivity.
