(59(4):228-236)Breeding of ‘Chuenfeng’ Peach

新品種台農3 號於1997年以‘台農甜蜜’為母本，‘Flordared’為父本進行人工雜交授粉，經12 年後於2009 年10 月取得品種權，商品名稱命名為‘春豐’是早熟豐產的用意，主要特性為：果實發育日數81–90 天，屬早熟種，盛產期比‘台農甜蜜’早約7–14 天。平均果重達143 g，屬大型果，果形圓整對稱，有茸毛，易剝皮，果肉白色，軟溶質。糖度高 (約11.7°Brix)，酸度低 (約0.38%)，風味甜，香氣濃。核為離核。需冷量170 CU (低溫單位)，適合中部平地及淺山坡地區種植。新品種具有母本‘台農甜蜜’之豐產、質優等優點，並導入父本極大果特性。同時彌補‘台農甜蜜’果實不大與‘Flordared’酸度高的缺點。新品種的表現對產業深具發展前途。 New peach cultivar Tainung No. 3 was originated from a cross between ‘Premier’ and ‘Flordared’ in 1997. After 12 years, plant variety right was granted in October 2010. ‘Chuenfeng’ peach was named for its early ripening time and high yielding. Fruits ripen ≈ 81 to 90 d after bloom in TARI, and belong to early ripening cultivars. Fruits are large, round-shaped, pubescence, easy peeled, white-fleshed, and melting. Fruit has a desirable soluble solids (11.7°Brix), low titratable acidity (0.38%), sweet, aromatic flavor, and freestone. Trees require 170 chill units (CU) and suitable for lowland areas of central Taiwan. This new cultivar combines both advantages of high yielding with good flesh texture from maternal parent ‘Premier’ and large fruit trait from pollen parent ‘Flordared’. Also, ‘Chuenfeng’ peach makes improvement on the disadvantages of small fruit size of ‘Premier’ and high acidity content of ‘Flordared’. The performance of ‘Chuenfeng’ is very promising for low-chill peach industry
