摘要：This is the first study on the relatively good performance of 42 carrot genotypes which grown in pots under open field conditions. Physical and chemical properties such as, shoot length, number of shoots, root length and diameter, texture, firmness and total soluble solid were examined and shown a significantly different among the 42 carrot genotypes. A total of 511 amplified fragments, with a polymorphic loci percentage 68 (13.3%), were developed from eight amplified fragment length polymorphism (AFLP) primer combinations. Each primer combination produced 42 to 93 bands with an average of 64 bands for each primer combination. Pairwise similarity indices vary from 0.430.94 amongst the 42 genotypes. Genotypes '67' and '68' showed the highest similarity index; whereas the most varied genotypes were '29' and '42'. All genotypes were grouped into four clusters based on Unweighted Pair Group Method with Arithmetic averages (UPGMA). The clustering of DNA by AFLP offers a powerful and convenient tool not only for assessment of genotypes, but also for revealing genetic relationships prior to the construction of a resource family for linkage analysis.
