Abstract: Genetic diversity of prolamins in 5 populations of Pinus tabulaeformis in North China was studied by using acidic polyacrylamide gel electrophoresis (APAGE) technique. 12 bands were identified from 95 samples on electrophoretic gel, 11 bands of them were polymorphic, and 23 band types were obtained. The percentage of polymorphic loci ranged from 16.67 % to 66.67%. The information index of Shannon and the gene diversity of Nei indicated that genetic diversity of Guandi population was higher than those of the others. The total genetic diversity of the species was 0.248 9, and the intrapopulation and interpopulation genetic diversities were 0.150 7 (60.55%) and 0.098 2(39.45%), respectively.

Key words: Pinus tabulaeformis, population, prolamin, genetic diversity
