聖誕紅新品種桃園核研1號及2號之育成
Release of Poinsettia New Cultivars 'TYNR No.1' and 'TYNR No.2'
摘要
本研究旨在育成適合台灣地區氣候條件及市場新奇多樣化需求之聖誕紅新品種，試驗以國內市場流通之38個品種經由輻射照射誘變，以選育出符合育種目標之優良新品種。其中聖誕紅新品種‘桃園核研1號’（原品系代號TYP97001）商品名「小桃紅」係以商業品種‘ECKESPOINT Freedom Red ’經輻射照射誘變所選育出之優良新品種，其苞葉色為深桃紅色，且葉片及苞葉形狀為現有市場少見的深鋸齒狀。聖誕紅新品種‘桃園核研2號’（原品系代號TYP97080）商品名「紅粉佳人」係以商業品種‘GUTBIER V-14 Pink ’經輻射照射誘變所選育出，苞片色為現有市場少見的亮粉色又帶有較底色深之粉紅暈，且外觀表現較一般之粉紅色苞片品種為明亮。兩個新品種之生長勢強、穩定性佳及適應性廣，適合作為各種盆徑大小之盆花產品。經觀察試驗、品系試驗、區域試驗及各項特性檢定，均表現優異。兩個新品種皆已取得我國之植物品種權，品種權利期間由2007年7月27日至2032年7月26日。

This study was conducted to develop the new cultivars of poinsettia that adapted to the climate and various marketing requirements in Taiwan. Mutation breeding was adopted by treating 38 current varieties by irradiation at Institute of Nuclear Energy Research. Through out a series of experiments, two elite lines TYP97001 and TYP97080 were selected, registered and released as new cultivars 'TYNR No.1' and 'TYNR No.2', respectively. 'TYNR No.1' (commercial name: Little red peach) mutated from the commercial variety 'ECKESPOINT Freedom Red' was characterized with dark-pink color and unique oak-leaf shape of bracts and leaves. 'TYNR No.2' (commercial name: Pink beauty) mutated from commercial variety 'GUTBIER V-14 Pink' had unique bright pink marble color in bract. The unique bract color, strong growth habit, good stability, wide adaptation and suitability for a variety of pot flowers were the advantages of these two new cultivars. The plant breeder rights for new cultivars 'TYNR No.1' and 'TYNR No.2' were approved and effective from July, 27 2007 to July, 26 2032.
