中文摘要 | 日日春新品種桃園1 號(原品系代號TYV07S2058)及桃園5 號(原品系代號 TYV07S2141),其於2008 年以日日春重瓣變異株TYV1 為種子親與單瓣品系TYV3 之花粉親經雜交組合,由第二代後裔族群選育而成。雜交種皆呈單瓣型,選其中15 株花徑大、生長勢強單株,並經自交獲得F2 族群。藉由雜交種遺傳重組變異,F2 族 群表現有單、重瓣,及其它變異性狀,從中選拔重瓣兼具優良園藝性狀植株,各繁殖 建立營養系,經兩代評估篩選,選出性狀優良之2 個重瓣日日春品系,分別命名為‘桃 園1 號-玫瑰女孩’及‘桃園5 號-紅娘’。新品種側枝數及花朵數多、株高較矮,適合盆 花栽培,花型均具兩輪10 片花瓣,花瓣排列緊密呈漏斗狀,花徑分別為3.1 及3.2 cm。 |
英文摘要 | Double-flowered vinca [Catharanthus roseus (L.) G. Don] TYV1 (female parent) was crossed with single-flowered TYV3 (male parent) and single-flowered F1 generation was obtained. Fifteen F1 plants with large flower and vigorous growth from both combinations were selected. Double-flowered F2 plants were obtained following self-pollination of these 15 F1 plants. Two double-flowered lines were selected and named as ‘Taoyuan No.1-Rose Girl’ and ‘Taoyuan No.5-Red Lady’ after selection and lines comparison tests. New double-flowered vinca cultivars have branching, multi-blooming, and compact characteristics, suitable for potted flowers. Double-flowered vinca have two layers of petal, funnel-shaped flower, and with 3.1 and 3.2 cm flower diameters, respectively. |
