| Research Abstract |
Genetic linkage map of a hybrid between Pinus pumila and P . parviflora var. pentaphylla was constructed in order to examine the pattern of introgressive hybridization between the two pine species. Haploid megagametophytes from 96 seeds of a putative F1 parent were analyzed with EST, SSR and AFLP markers. The analysis resulted in 483 loci (64 ESTs, 2 SSRs and 417 AFLPs) mapping to 13 linkage groups under the criteria of LOD4.2 and θ<0.4.
