The Chromosomal Architecture of Cicer anatolicum Alef., a Wild Perennial Relative of Chickpea

Abstract

Chromosomal architecture of Cicer anatolicum Alef., a wild perennial relative of chickpea, was studied to assist in determining phylogenetic relationships within the genus Cicer L. The diploid chromosome number was confirmed as 2n=16. Mean haploid chromosome complement length and mean chromosome length were 18.88 and 2.36μm, respectively. The karyotype was asymmetrical and characterized by one metacentric, six submetacentric and one acrocentric chromosome pairs. The longest chromosome pair (acrocentric) carried a conspicuous secondary constriction on the long arm. The karyotype of C. anatolicum is compared to that of other annual Cicer species and further phylogenetic relationships discussed.
