Phylogenetic relationships in Lens species and their interspecific hybrids as measured by morphological characters

Abstract

Phylogenetic relationships of 15 genotypes of the genus Lens and 7 of their interspecific hybrids were determined by morphological (quantitative and qualitative) characters. The first multivariate analysis was conducted on quantitative characters and second analysis was conducted on qualitative characters. In the first analysis on the basis of two canonical variates, accessions of Lens nigricans, L. odemensis and L. culinaris ssp. orientalis grouped together, while L. ervoides and L. culinaris ssp. culinaris formed two different groups. The second analysis yielded different results based firstly on two canonical variates where L. nigricans and L. culinaris ssp. culinaris formed two separate groups but the other three (sub)species clustered together when the third canonical variate was included. L. odemensis separated from this larger group and formed a separate group. The phylogenetic relationships of parents and their hybrids have also been discussed.
