‘连童’草莓是以‘童子1号’为亲本,以引发连作障碍主要因子尖孢镰刀菌毒素和自毒物质对羟基苯甲酸混合液为选择压力,利用组织培养技术诱变选育的新品种。果实长圆锥形,果面光滑,有蜡质光泽。果味微酸,香味浓,果肉橙红至红色。含可滴定酸0.17%,可溶性固形物11.3%,总糖7.9%,维生素C 0.793 mg·g~(-1)。果实硬度2.325 kg·cm~(-2),耐贮运。抗枯萎病、灰霉病和白粉病。产量在34 500kg·hm~(-2)以上,适合在河北、山东等省露地、拱棚和温室栽培。与‘童子1号’相比,连作障碍发生程度明显减轻。
’Even Tong’ strawberry is based on ’Tongzi No.1’ as the parent, which takes the selective pressure of Fusarium oxysporum toxin and toxic compound p-hydroxybenzoic acid as the main factor that causes the continuous cropping obstacle and uses the tissue culture technology to mutate and select the new Variety. Fruit long conical, smooth fruit, waxy gloss. Fruity slightly acidic, fragrant, red orange to red flesh. 0.17% of titratable acid, 11.3% of soluble solids, 7.9% of total sugar and 0.793 mg · g -1 of vitamin C. Fruit firmness 2.325 kg · cm ~ (-2), resistant to storage and transportation. Fusarium wilt, gray mold and powdery mildew. The output is more than 34 500kg · hm -2, which is suitable for open field, arch shed and greenhouse cultivation in Hebei and Shandong provinces. Compared with that of “boy 1”, the degree of continuous cropping obstacle obviously reduced.
