Abstract

The genetic diversity and relationship of 44 tomato accessions were analyzed by AFLP (amplified fragment length polymorphism).Fifteen primer combinations selected from 64 primer combinations produced a total of 601 fragments,364 of which were polymorphic with a polymorphism percentage of 60.5%.This results showed that there were abundant diversities in enzyme digestion sites among different tomato varieties.These tomato germplasm resources were clustered into 5 multiple-member groups and 1 one-member group by UPGMA (unweighted pair group method with arithmetic average) based on Nei's genetic distances.The genetic relationship of 44 tomato accessions was analyzed using the different coefficient.
