Abstract

Capsicum (pepper) is a member of the Solanaceae family and this genus has a great economic importance in food, drug, spices and industry. In this study, seeds of ten ecotypes of Capsicum spp. were obtained from the plant gene bank of Seed and Plant Improvement Institute of Karaj, Iran. The standard karyotype was prepared for the ecotypes and the characteristics of the chromosomes including long arm, short arm, total length (TL), arm ratio and centromeric index were calculated and chromosome types were determined. The number of chromosomes in somatic cells of all genotypes was 24 (2n=2x=24). All genotypes had a pair of satellite chromosome. The first 2 principal component analysis (PCA) justified over 99% of the total variations determined for cytological parameters. The highest total haploid length (51.65 μm) was detected in G7 while G8 demonstrated the least (43.46 μm). Cluster analysis was carried out for chromosomal parameters, classifying genotypes in three classes.
