草莓育种中杂交组合优化配置及应用实例(英文)

为培育早熟、优质、抗病的草莓新品种(系),改良现有生产上主栽的日本草莓品种红颊不抗炭疽病的缺陷,该研究采用以不抗病的日本草莓品种红颊为母本,抗病性较强的欧美品种温塔纳和弗吉尼亚、日本品种明宝等为父本配置正反交杂交组合,研究了不同杂交组合F1后代在果实、产量、品质、繁苗系数、抗病性等方面的表现,并通过育种实例F1-40优系的获得,对杂交组合的表现加以佐证。

Optimization of Hybrid Combination and an Application Example for Strawberry Breeding

This study was conducted to select new strawberry cultivars with early maturity, disease resistance and high quality, by optimizing the hybrid combinations of Benihoppe, a Japanese strawberry cultivar, which is extensively planted but not resistant to anthrax. The reciprocal crosses were performed using Benihoppe, as the female parent, four disease-resistant European cultivars Albion, Camino Real, Ven- tana and Virginia, and one Japanese cultivar Meiho as the male parent. Then, the seedling propagation coefficient, disease resistance, fruit quality and yield of F1 gen- eration of the combinations were detected and compared. Besides, the breeding and traits of a new cultivar F1-40 developed from the cross between Benihoppe and Mei- ho were introduced as an instance to prove the feasibility of the combinations/lines.
