摘　　要：为了探讨小麦F1代谷蛋白大聚合体(glutenin macropolymer,GMP)含量的杂种优势以及GMP含量与农艺性状的关系,用6个小麦亲本材料,按照Griffing方法Ⅱ组配一套杂交组合,测定和分析了F1代GMP含量及其与农艺性状的相关关系。结果表明,大部分杂交组合GMP含量的平均杂种优势呈现负向效应。GMP含量的遗传呈现出倾向于低值亲本的趋势。GMP含量与株高、穗长、单株生物产量、单株粒重、千粒重、单株粒数、收获指数等农艺性状相关不显著,有利于高产优质的结合改良。因此,通过合理组配亲本和选择,可望获得GMP含量高,烘烤品质好和农艺性状优良的丰产品系,从而提高中国小麦的烘烤品质。Abstract： GMP content is closely correlated with wheat baking quality. A set of diallel crosses involving 6 wheat parents, according to the model of Griffing Method Ⅱ, was made to determine GMP contents and agronomic characters in F1 and the relationship between GMP contents and agronomic characters. The resuits indicated that the average heterosis of GMP content for most of the cross combinations were negative in effect. The heredity of GMP content trended to low value parent. The correlations between GMP content and plant height, head length, biomass per plant, kernel weight per plant,1000-kernel weight, kernel number per plant and harvest index were not significant, it was practicable for combining yield and quality. It was likely to obtain lines with high GMP content, high baking quality, desirable agronomic characters and high yield potential by crossing parents, selecting progeny correctly and improve wheat baking quality.
