摘要： Ponkan is one of the two easy-peeling mandarins grown in China, and 'Xinnu' Ponkan (Citrus reticulata Blanco) is a major cultivar in the industry. We selected a spontaneous mutant of 'Xinnu' named `Zaomi' Ponkan. Compared to the wild type, `Zaomi' Ponkan exhibited alternating agronomic traits comprising earlier colouring, thinner peel, fewer seeds and higher sugar content. Pollen analysis showed that `Zaomi' produced a greater number of deformed, nonviable pollen grains. Experiments in self-and cross-pollination suggested that self-incompatibility of `Zaomi' contributes to the seedlessness of `Zaomi' x `Zaomi'. Fruit quality analysis demonstrated that `Zaomi' was a high-sugar mutant that was not affected by pollinating combination. This study on the fruit characteristics of `Zaomi' indicates that partial male sterility and self-incompatibility contributes to fewer or no seeds; natural pollination promotes the overall fruit quality of `Zaomi' Ponkan. These results provide an explanation of the seed formation of `Zaomi' Ponkan and supply information relevant to its commercial planting.
