A type avocados have female flowers in the morning and male flowers in the afternoon, The reverse exhibition occurs on B type cultivars. So it is needed to plant cultivars of two types row by row in orchards to get fruit. In some cases, such as low temperature or high relative humidity during flowering period, it is possible that self-pollination could happen. And we can produce avocado fruits by planting one cultivar in large areas. This research is planned to study the flowering period and floral behavior in Taiwan for understanding the possibility of self-pollination. Then Random Amplified Polymorphic DNA (RAPD) method is used to calculate the self-pollination rate of avocado fruits. According to the meteorological data, regions with the potential to have one cultivar for production use will be evaluated. Now in Taiwan avocado fruits are produced at Chiayi and Tainan. Once the method for calculating self-pollination rate of avocado fruits is established, it is useful for local field test to determine proper planting strategies. And with production area at different latitude and sea level to produce off-season avocado fruits, we can have avocado fruits all year round.酪梨逢機多型性DNA條帶分析自交結實率RAPDavocadoself-pollination rate
