Karyotype of the kabuli-type chickpea (Cicer arietinum L.) by image analysis system

Abstract

Detailed information on karyotype of the kabuli-type chickpea (Cicer arietinum L.) has been lacking; hence this study was undertaken to produce the standard karyotype of kabuli chickpea and to understand the variation in karyotype within kabuli type. Mitotic analysis of four genotypes differing in morpho-agronomic traits and geographic origin were carried out. Little difference was observed among the four genotypes for total genome length, chromosome length and complement formula. All carry a distinguishable satellite on the longest chromosome pair. Small variation in karyological parameters within kabuli type might be due to its narrow adaptation. The karyotype of the variety Sultano has been chosen as the standard for kabuli-type chickpea on the base of its parameters being closest to the average of those genotypes that were investigated
