Abstract:

    Prunus campanulata Maxim. is one of the native plants in Taiwan. The attractive fruits are red, small and astringent. It was only used for ornamental planting with low edible value. The objectives of this research are to improve the fruit size and economic value of P. campanulata Maxim. by natural field selection. Field selections were conducted at fruiting period in five lowland regions. Average fruit weight for 220 sampling trees ranged for 0.36 to 1.33 g, 63.8% to 86.1%. for flesh proportion, 7.4 to 19.0 °Brix for total soluble solid, and 0.5 to 3.0% for titratable acidity. Eight good selections were under evaluation and utilization.
