Proceedings of A Symposium on Breeding of Fruit Crops in Taiwan
In order to solve the disadvantages of Taiwan local plum varieties, such as short harvest period, high acidity, and small fruit size, Taiwan agricultural Research institute began the plum breeding program since 1998. Some foreign elite plum cultivars with characteristics like low acidity and large fruit size were introduced, combining with previous introduced high-chill cultivars grown at high mountain area, were used as genetic material to improve the quality of local plum varieties. These cultivars were chosen as praents and crossed with local varieties, e. g. ‘Yilan’, ‘Singcai’, ‘Hualuo’, ‘Hianggan’, and ‘Hongrou’ plums. The breeding goals are to develop new cultivars with low chilling requirement, early maturing, low acidity, sweet flavor, and medium to large fruit size. Now twenty two good clones were selected from hybridization seedlings and further evaluation will be recorded for tree growth phenology and fruit quality.
