获得了(普通小麦×巨大冰麦草)×普通小麦BC_1、BC_2F_1,第1、2次回交结实率分别为2.7％和21.2％。BC_2F_1部分可育,未经人工授粉的56株结实5232粒。BC_1、BC_2F_1和BC_2F_2的2n分别为54～56,40～53和39～52、BC_2F_1和BC_2F_2植株用强菌株JF-1,7,11,12的混合菌液或F-4,15,17,34的混合液接种鉴定,均分离出赤霉病抗性明显高于对照品种的植株。表明将巨大冰麦草的赤霉病抗性导入普通小麦是可能的,由此而创建比现有普通小麦抗病品种更加抗赤霉病的育种材料也是有希望的。文章还对赤霉病抗性转移过程中怎样防止抗性减弱或丢失进行了讨论。
Obtained (common wheat × huge ice straw) × common wheat BC_1, BC_2F_1, the first and second backcrossing fruiting rate was 2.7% and 21.2%. BC_2F_1 partially fertile, non-pollination of 56 plants 5232 grains. 2n of BC_1, BC_2F_1 and BC_2F_2 were 54-56, 40-53 and 39-52, respectively. The mixed cultures of strains BCF 2 and BC 2F 2 with strains JF-1,7,11,12 or F-4, 34 mixed inoculation identification, were isolated scab resistance was significantly higher than the control varieties of plants. Suggesting that it is possible to introduce the fescue resistance of giant ice straw into common wheat, thereby creating a breeding material more resistant to Fusarium head blight than the existing conventional wheat cultivars. The article also discussed how to prevent the resistance from decreasing or losing during the process of scab resistance.
