| Abstract | The genetic relationships among Thai pummelo cultivars were estimated using simple sequence repeat (SSR) markers developed for Citrus spp. Fifty three clones, including outstanding commercial cultivars, local cultivars from northern, central and southern provinces of Thailand and foreign cultivars were evaluated using 13 SSR markers. The results show that 10 SSR markers are polymorphic and generate a total of 33 alleles. The average value of the expected heterozygosity and polymorphism information content are 0.52 and 0.45 respectively, and the combined probability of the identity value of the 10 SSR markers is 6.82 ? 10-6. The similarity index (SI) ranges from 0.44 to 1.0. The pummelos can be clustered into seven groups and one out-group by unweighted pair group method with arithmetic averages. Most pummelos including commercial cultivars and hybrids of 'Thong Dee' and of 'Ta Khoy' are classified in the same group (SI = 0.67-1.00), whereas local and foreign cultivars are more diverse than commercial cultivars (SI = 0.44). |
