摘要:

品质是小麦育种的主要目标性状之一,受多种因素的共同影响。黄淮麦区是中国小麦的主要产区,同时也是强筋和中强筋小麦的优势种植区。本研究利用主成分分析(Principal component analysis, PCA)、模糊综合评价(Fuzzy comprehensive evaluation, FCE)和分子标记鉴定相结合的方法,对黄淮麦区436个小麦品种的七个关键品质性状以及两个重要的品质相关遗传位点Glu-1Sec-1进行了多维度的系统评价。结果表明,稳定时间(Stability time, ST)、拉伸面积(Stretch area, SA)和最大阻力(Maximum resistance, MAXR)是影响黄淮麦区小麦品质的三个关键性状,Glu-1Sec-1主要影响这三个性状,进而对小麦品质产生影响。与高分子量麦谷蛋白亚基位点Glu-A1Glu-B1相比,Glu-D1对综合评价值D、主成分PC1-PC3PC1主要构成性状STSAMAXR的影响更为显著。对于Glu-D1位点,携带Dx5+Dy10等位基因小麦品种的STSAMAXR显著优于携带Dx2+Dy12等位基因的品种,表明Dx5+Dy10可能通过提高STSAMAXR来提升小麦品质。结合综合评价值DGYT(Genotype by yield×trait)指数和HMW-GS评分,筛选20个优质高产的小麦品种,可作为优异亲本应用于小麦品质育种。

Abstract:

Wheat (Triticum aestivum L.) quality is a major focus of wheat breeding, which is influenced by multiple factors. The Huang-Huai wheat region, one of the main wheat-producing areas in China, provides favourable conditions for cultivating wheat cultivars with strong-gluten and medium-strong-gluten. In this study, a systematic assessment of seven crucial quality traits and important genetic loci (Glu-1 and Sec-1) in 436 wheat cultivars in the Huang-Huai wheat region of China by principal component analysis (PCA) and fuzzy comprehensive evaluation (FCE) methods showed that the stability time (ST), stretch area (SA), and maximum resistance (MAXR) were identified as three key factors, which significantly influenced wheat quality. Glu-1 and Sec-1 primarily impacted these three traits and subsequently influenced wheat quality. Compared to Glu-A1 and Glu-B1, Glu-D1 has a more significant impact on the comprehensive evaluation value D, principal components PC1-PC3, and the main traits ST, SA and MAXR of PC1. Wheat cultivars carrying the high-molecular-weight glutenin subunit (HMW-GS) Dx5+Dy10 exhibited a notable improvement in ST, SA, and MAXR traits compared with those carrying HMW-GS Dx2+Dy12, suggesting that Dx5+Dy10 may enhance wheat quality by improving ST, SA, and MAXR. By combining the results of D value, GYT (genotype by yield×trait) index, and HMW-GS score, 20 high-quality and high yield wheat cultivars were identified, which can be used as elite parents for wheat quality breeding.
