摘　　要：为探明不同胞质背景对杂种小麦面包加工品质的影响,测定了4个强筋品种与4个中弱筋品种按NCII设计配制的32个正反交组合及T型、K型、AL型、A型4种胞质背景的14个组合的F2籽粒的硬度、GMP含量、Zeleny沉淀值、面团流变学参数和面包体积等面包加工品质性状。结果表明:①强筋组亲本对除吸水率和评价值之外的其他面包加工品质性状均具有显著的有利于面包加工品质的普遍胞质效应;豫麦34、郑麦9023和陕优225在多个面包加工品质性状方面具有显著有利的一般胞质效应;陕优225的面包体积的一般胞质效应为14 mL,达到5%的显著水平。因此,在面包小麦育种中要注意安排强筋亲本作母本。②就面包体积而言,T型和K型不育胞质相对于A型胞质具有有利的一般胞质效应,AL型不育胞质与A型胞质相当。组合T-西农772×AL-R1的T型不育胞质的个别胞质效应为60 mL,组合K-西农772×T6-3的K型不育胞质的个别胞质效应为98 mL,且均达5%的显著水平。T,K和AL型不育胞质可用于面包小麦杂种优势利用。To detect the effects of different cytoplasmic background on bread-making quality properties of hybrid wheat, 32 crosses from 4 strong gluten and 4 mid/weak gluten wheat euhivars based on NCⅡ design, and 14 crosses from euhivars with T-, K-, AL- and A-type cytoplasm were made, respectively. F2 seeds of each cross were harvested and used to test the hardness, GMP content, Zeleny-sedimentation value, Farinograph parameters and Loaf volume. The results showed that the strong-gluten cytoplasm（Yumai34, Zhengmai9023 and Shanyou225）had positive effects on all bread-mak- ing quality properties, except water absorption and Valorimeter value, so the strong gluten wheat eultivar should be used as female parent in the program of bread wheat breeding. The T-and K-type CMS cytoplasms had general positive effect on Loaf volume, compared to A-type and AL-type CMS cytoplasm. The effect of CMS cytoplasm on loaf volume for crosses T- XN772 × AL-R1 and K-XN772 × T6-3 reached to 60 and 98 mL, respectively. The T- , K- and AL-type CMS cytoplasm may be used in the program of bread wheat heterosis utilization.
