Abstract

A single population of the Mediterranean species Lens ervoides was located in Ethiopia and seeds were collected. Based on chromosomal arrangement and isozyme profile the Ethiopian L. ervoides is similar to populations of this species in the Mediterranean region. All hybrids between L. ervoides from Ethiopia and an accession of this species from Israel were dwarf, whereas hybrids between the former and an accession from Algeria were normal. Segregation in F₂ and BC generations indicated that the dwarf habit in lentil is governed by dominant alleles of two complementary genes designated df₁ and df₂. The dominant allele of another gene, dfi, inhibits the dwarf phenotype. The evolution of L. ervoides from Ethiopia and its potential as a genetic resource are briefly discussed.
