摘要

為育成適應本省氣候環境，株型直立，果實碩大、鮮紅亮麗、硬實且糖度高，早期產量與總產量高之早生品種，75年春季以Sequoia為母本，久能早生為父本，進行人工雜交授粉，選育優良單株76-18，歷經系統、品系與區域試驗，於82年3月26日命名為「桃園二號」，商業名稱為「艷紅」。本品種夏季育苗容易、幼苗繁殖倍數高，植株直立，葉面積大，生育旺盛，開花結果期與桃園一號相近，屬早生品種，種子少、花柱短、果實碩大，無縱溝，外觀光滑亮麗，糖度與硬度中等，果實貯藏性佳，早期產量與總產量高；葉片老化速度慢，減少摘葉次數，耐霜性強，果實較桃園一號耐疫病，而對白粉病、灰黴病、葉芽線蟲、蟎類與薊馬等耐性則與桃園一號差異不顯著。

並列摘要

A new strawberry cultivar ”Taoyuan No.2” was selected from the cross Sequoia X Kunowase in spring 1986 at Taoyuan District Agricultural Improvement Station, and was released on March 26, 1993. The commerical name is ”Yen-Hong”. It is a variety performed very vigorous in growth, easy to produce runner-plants, erect plant type, green in leaf color and with a large area of mid-leaflet. The berry is large in size, conic in shape, shiny and red-colored. The flesh berry is juicy, firm and with medium sugar content. Taoyuan No.2 has high rates of normal fruits and the marketability is fairly good. In addition, Taoyuan No.2 had higher total and early season yields than that Taoyuan No.1 The performance of other horticultural characteristics such as better fruit quality, more tolerance in storage life, frost and phytophthora blight were compared to Taoyuan No.1 There was no difference between the two cultivars in the resistance to powdery mildew, gray mold rot, leaf-bud nematode, mite and thrips.
