红花草莓‘俏佳人’与白花品种‘佐贺清香’杂交后代性状调查

The Characteristics of Hybrids from the Cross of Red-flowered cv 'Pretty Beauty' and White-flowered cv 'Sagahonoka' in strawberry

[目的]改良重要性状,培育观赏兼食用的红花草莓新品种。[方法]通过红花草莓品种‘俏佳人’(花深粉色)与栽培品种‘佐贺清香’(花白色)进行杂交,改良红花草莓的果实等重要性状。[结果]以‘俏佳人’为父本的结实率(60.0%)高于其作为母本时的32.3%;后代花色虽发生分离,但均浅于‘俏佳人’;后代的果实形状变化较大,有的果实品质、大小等性状显著优于红花亲本。[结论]从后代中筛选出观赏兼食用的红花草莓新种质,如株系1-31、2-23等,花色鲜艳、果实品质优良。

[Objective] To improve the important traits and breed novel red-flowered strawberry cultivars with ornamental flowers and edible fruits.[Method] The red-flowered strawberry cultivar‘Pretty Beauty＇was used to cross with white-flowered cultivated cultivar ‘Sagahonoka＇to improve its fruit size and fruit quality.[Result] The fruit-setting rate of ‘Pretty Beauty＇as male parent（60.0%）was higher than it as female parent（32.3%）.The flower color was segregated in their hybrid offspring,but lighter than the flower color of‘Pretty Beauty＇;And the fruit shape of the hybrids varied greatly.The fruit characteristics of some hybrids were significantly superior to red-flowered parent. [Conclusion] The novel red-flowered strawberry germplasms with ornamental flower and edible fruit were seclected such as 1-31 and 2-23.
