title: The fine structure of chickpea (Cicer arietinum L.) chromosomes as revealed by pachytene analysis.
abstract: A standard pachytene karyotype of chickpea (Cicer arietinum L.) is presented for the first time. Individual pachytene chromosomes were identified and described in detail. An idiogram was prepared on the basis of chromosome length, arm ratio, and distribution of heterochromatin and euchromatin. Chickpea pachytene chromosomes belong to the "differentiated" type with darker staining heterochromatin proximal to and lighter staining euchromatin distal to the centromeres. Chromosomes were numbered from 1 to 8 following a descending order of length. The total length of the chromosome complement at pachytene was 335.33 μ, and chromosome size ranged from 58.05 to 30.53 μ.
