영문 초록

To select excellent diploid parental lines for potato breeding, the mechanisms of 2n pollen formation, the frequency distribution of the mechanisms, the frequency of 2n pollen, and the frequency distribution of pollen grain diameter were investigated in eighty-two progeny clones derived from W 5337.3 × W5295.7. In twenty-nine progeny clones, the frequency of stainable 2n pollen was higher than 30 percent. The size of n and 2n pollen was clearly divided in the range of 17.5-25.0μ and 27.5-37.5μ, respectively. The mechanisms of 2n pollen formation in the eighty-two progeny clones were found to be parallel spindles(ps), premature cytokinesis(pc) and synaptic mutant(sy). In some clones they were formed by the combination of ps+ pc and ps+ sy
