Proceedings of A Symposium on Breeding of Fruit Crops in Taiwan
Peach production mainly can be divided in high mountain and low land types of Taiwan. In order to lessen the environmental impact due to high mountain plantation, research finance is supported by the government to develop low-chill peach cultivars for friendly relations to environment and sustainable development of peach industry. More than 189,643 flowers have been hand pollinated and including open pollination totally 19,263 seedlings have been successfully raised since 1996. Peach breeding objectives are to develop low chilling requirement, low acidity, early maturation, large fruit size, attractive appearance, and different ripening stages. Through selection procedure, 5 new low-chill cultivars named ‘Premier’, ‘SpringHoney’, ‘SummerHoney’, ‘Chuenfeng’, and ‘Red Jade’ were registered and released. Cultivation area of thes cultivars reached more than 60% of total production. In order to increase the diversity of peach fruit types, nectarines, flat peaches, and dual purpose (ornamental and fresh consumption) will be the next selection goals. For coping with climate change, very low-chill cultivars need to develop for insufficient chilling requirement during mild winter which will be the core work for peach breeding and being the fundament of localizable, qualitative, diverse, and sustainable development of peach industry.
