    Abstract:

    mplified fragment length polymorphism (AFLP) technology was used to analyze the genetic variation and genetic structure among three populations of In total, 315 loci were amplified with five primer pairs, and 311 of these loci were polymorphic, acco- unting for 98.73%. Shannon genetic diversity indices were 0.477 1±0.260 6, was 0.411 6, while it was 0.131 6 between F1 and their female parents, and 0.278 0 between F1 and their male parents. The dendrograms showed that the three population gathered independently, which . AMOVA analysis indicated that 30.47% of variance was among populations and 69.53% variance was within populations, which suggested rich genetic diversity level within populations. In all, the expression of heterosis has a correlation with the genetic variation.
