| Pecan is deciduous tree and belongs to the Julandaceae family. Pecan is an economically important as a nut and timber crop. Heterozygosity is expected to be high for typically cross-pollinated. Yet little is known about the nature of genetic variation within this species. In addition, the pedigree of many pecan cultivars remains unknown or is questionable. In this study, the phylogenetic relationships between 22 pecan cultivars and its analyzed by RAPD (randomly amplified polymorphic DNA). PCR Amplification used 40 randomly selected oligoes as primers. Based on their genetic similarities derived from the RAPD data, the 22 pecan cultivars were classified into different five groups in agarose gel. The 22 pecan cultivars were classified into five sectional groups by UPGMA clustering analysis, too. C. flacra and Black walnut showed the 0.9 of similarity index and Farley, Pawnee showed the 0.85 of similarity index. The 22 pecan cultivars were classified into different five groups by analysis of the 4% polyacrylamide gel fraction. (Group I : 1, 2, 3, 4, 13, 16, 17, 20, 21 Group II : 14,18 GroupIII : 6,12 GroupIV : 5, 11, 15, 19, 22 CroupV : 7, 8, 9, 10) Group V show the 1.0 of similarity index and Farley, Sturya, Clarke, Pawnee show the 0.98 of similarity index and Kiowa, Schley show the 0.92 of similarity index. Results from this study indicated that RAPD can be used to establish the genetic relationships among the 22 pecan cultivars. Similarity coefficients generally agreed with what would be predicted in cultivars with known pedigrees, and we could accurately construct relationships among cultivars. In addition, we have shown that RAPD provides useful information on the origin of unknown cultivars. |
