Abstract:

This paper described the population structure of P. ussuriensis Kom. The fourteen random primers chosen for analysis generated 180 bands that ranged in size from 211 bp to 1636bp. Estimates of Shannon's phenotypic diversity index ranged between 0.271 and 0.392, averaging 0.310. Analysis of molecular variance partitioned the RAPD variation into the among-and within-population components. The among-population components accounted for 62.3% of the variation and within-population accounted for only 37.7%. Estimates of Ho also varied among primers, with CH1-1, detecting. Highest (0.540) and 2116 detecting the lowest (0.151) value Of diversity.

Key words: Populus, Natural population, RAPD, Genetic sbucture
