@article{fdi:010022315, title = {{A}llozyme diversity of cultivated cowpea {V}igna unguiculata ({L}.) {W}alp}, author = {{P}asquet, {R}{\'e}my}, editor = {}, language = {{ENG}}, abstract = {{A} survey of allozyme variation in cultivar-groups of cowpea (#{V}igna unguiculata$ ({L}.) {W}alp.) was undertaken by examining 21 enzyme systems encoded by 36 loci in 271 accessions representing the five cultivar-groups. {V}ery low levels of variation were found within accessions, which is typical of self-pollinating species. {L}ittle variation was also found among accessions. {C}ompared with other legume crops, #{V}. unguiculata$ is depauperate in allozyme variation. {W}e found an average of 1.61 alleles per locus with 42% of the loci polymorphic and a total heterozygosity of 0.061. {O}f the variation present, 90% was found within cultivar-groups, while 10% was among cultivar-groups. {D}ata analyses revealed continuous variation among cultivar-groups and geographic regions with the accessions failing to segregate into discrete morphophysiological or geographic clusters. {H}owever, evolved cultivar-groups (cv.-gr. #{M}elanophthalmus$ and cv.-gr. #{S}esquipedalis$) appear to be less diverse than their putative primitive cultivar-group progenitors. {D}ue to lack of availability of critical material, no clear center of origin can be established. {H}owever, the data presented suggest that {N}ortheast {A}frica could be a possible center of domestication.
