Origin, classification, variation and distribution of lima bean (Phaseolus lunatus L.) in the light of Cuban material

Phaseolin diversity in wild Lima bean (Phaseolus lunatus L.) in American centres of origin

“…Recently, given the high occurrence of intermediate forms (Maquet et al, 1990;Esquivel et al, 1990) and the results of biochemical evidence (Lioi, 1994), the terminology large-, intermediate-, and small-seeded morphotypes has been adopted. Different authors have tried to locate the origin of P. lunatus in the New World and to explain its domestication.…”

Variation among Spanish faba beans cultivars: taxonomic and evolutionary implications

“…Results reported by several authors (De Pace et al ., 1988 ;Hamon & Sloten, 1989;Esquivel et al ., 1990;Rezal & Frey, 1990;Jaradat, 1991) clearly show that univariate and multivariate analysis could be effectively employed in different species to evaluate germplasm collections, assessing the relative contribution of different characters to the total divergence between population . These analyses can also assist the breeder in planning breeding programs .…”

The Cuban homegarden ?conuco?: a perspective environment for evolution and in situ conservation of plant genetic resources

“…(1991b) studied seed characters of 173 accessions of P. lunatus collected in Cuba, showing that not only the three cultigroups described by Baudet (1977) were present in Cuba, but also landraces showing intermediate characteristics could be found . A more detailed study was further carried out (Esquivel et al ., 1990a) . Seed morphological characters were analysed by univariate and multivariate statistical methods .…”

“…The two other taxa mentioned turned out to be forms of this species, too. Some weedy types of Phaseolus lunatus L. have been found near cultivated areas or in dry forests of Cuba (Esquivel et al ., 1990a) which have been considered as regressive forms of the 'sieva' types . Introduced crops with specific purposes, have been found far away from the places where they were introduced, growing in wild or semi-wild conditions .…”
