| Outline of Final Research Achievements |
Using NGS, we developed a sex-specific marker for androdioecious Schizopepon bryoniaefolius. This can be used in the reproductive stage of heterozygotic males, although there is a restriction in using in natural populations. From the view of the transmission advantage, we investigated the ratio of a sex-specific marker in pollen grains of heterozygotic males. Because of large differences among individuals, the ratio was not deviate from 1:1. However, it may imply that there remains a possibility that some males produce more pollen with the male-determinant gene. We did not find significant differences between sexes in pollen germination rate, growth rate, and survival rate.
