摘要:

【目的】检测新疆春小麦品种Pins等位变异分布规律,分析不同Pins基因型春小麦品种籽粒硬度的差异,探讨Pins对春小麦品种主要品质性状和新疆拉面加工品质的影响,明确籽粒硬度影响新疆拉面加工品质的分子遗传基础及机理。【方法】以386份新疆春小麦品种资源为材料,用分子标记检测籽粒硬度Pins,测定品质性状(籽粒性状、磨粉品质、面粉品质、面团特性、淀粉糊化特性等),制作新疆拉面并进行评鉴。【结果】Pins等位变异分布规律:在新疆春小麦品种资源中,Pina有2种等位变异,分别为Pina-D1a(占比86.79%)、Pina-D1b(13.21%);Pinb有3种等位变异,分别为Pinb-D1a(64.77%)、Pinb-D1b(32.12%)和Pinb-D1p(3.11%);Pina/Pinb有6种基因型组合,分别为Pina-D1a/Pinb-D1a(58.81%)、Pina-D1a/Pinb-D1b(25.39%)、Pina-D1a/Pinb-D1p(2.59%)、Pina-D1b/Pinb-D1a(5.96%)、Pina-D1b/Pinb-D1b(6.74%)和Pina-D1b/Pinb-D1p(0.52%)。Pins对春小麦品种品质性状的影响:Pina-D1a的籽粒蛋白含量、灰分含量、白度、湿面筋含量、Zeleny沉淀值均显著高于Pina-D1b;籽粒硬度、黄度(b*值)、面筋指数、峰值时间、8分钟面积、稀懈值均显著低于Pina-D1b。与其他等位变异相比,Pinb-D1a的白度、湿面筋含量,Pinb-D1b的出粉率、黄度(b*值),Pinb-D1p的籽粒硬度、面筋指数均最高且达显著差异水平。与其他基因型组合相比,Pina-D1a/Pinb-D1a的白度,Pina-D1a/Pinb-D1p的籽粒硬度、面筋指数、8分钟面积,Pina-D1b/Pinb-D1b 的淀粉稀懈值,Pina-D1b/Pinb-D1p的籽粒蛋白含量、出粉率、面粉的湿面筋含量均最高且达显著差异水平。Pins对新疆拉面加工品质的影响:Pina-D1a的拉面手感、粘弹性、总分极显著低于Pina-D1b;Pina-D1b/Pinb-D1p的拉面手感最好,Pina-D1a/Pinb-D1pPina-D1b/Pinb-D1aPina-D1b/Pinb-D1b的粘弹性最高;Pina-D1b/Pinb-D1aPina-D1b/Pinb-D1b的总分最高。【结论】Pina突变会使新疆春小麦胚乳质地变硬、主要品质性状显著升高,促进新疆拉面的拉面手感和粘弹性等性状得到显著改善,最终促使新疆拉面的加工品质(总分)显著提升;Pinb变异对新疆拉面加工品质的影响不显著。Pina-D1b/Pinb-D1aPina-D1b/Pinb-D1b是优质新疆拉面小麦品种品质改良中重点选择的基因型组合类型。

Abstract:

【Objective】The objectives of this study were to detect the allelic variations of Pins genes in Xinjiang spring wheat varieties, analyze the difference of grain hardness among different Pins genotypes of spring wheats, and explore the effects of Pins genes on different quality characters and the processing quality of Xinjiang hand-stretched noodles.【Method】First, the allelic variations of Pins genes in 386 Xinjiang spring wheats varieties were detected with molecular markers. Second, the quality characters of these materials were determined, including milling quality, gluten quality, dough character, and starch gelatinization character. Third, the processing qualities of Xinjiang hand-stretched noodles were evaluated. 【Result】The allelic variations of Pins genes: In Xinjiang spring wheat varieties, there were two alleles (Pina-D1a and Pina-D1b) at Pina locus with proportions of 86.79% and 13.21%, respectively, three alleles (Pinb-D1a, Pinb-D1b, Pinb-D1p) at Pinb locus with proportions of 64.77%, 32.12%, and 3.11%, respectively, and six genotype combinations (Pina-D1a/Pinb-D1a, Pina-D1a/Pinb-D1b, Pina-D1a/Pinb-D1p, Pina-D1b/Pinb-D1a, Pina-D1b/Pinb-D1b, Pina-D1b/Pinb-D1p) for Pina/Pinb with proportions of 58.81%, 25.39%, 2.59%, 5.96%, 6.74%, and 0.52%, respectively. The effect of Pins gene on the quality characters of Xinjiang spring wheat: the grain protein content, and flour ash content, whiteness, and wet gluten content, Zeleny sedimentation value with Pina-D1a were significantly higher than those with Pina-D1b (P<0.05), whereas the grain hardness, flour yellowness (b*), gluten index, mid line peak time, 8 min integral, and starch breakdown of Pina-D1a were significantly lower than those of Pina-D1b (P<0.05). Among different alleles of Pinb, the flour whiteness and weak gluten content of Pinb-D1a, the grain flour yield and flour yellowness (b*) of Pinb-D1b, and the grain hardness and flour gluten index of Pinb-D1p were significantly higher than those of other alleles (P<0.05). Among different genotype combinations of Pina/Pinb, the flour whiteness of Pina-D1a/Pinb-D1a, the grain hardness, flour gluten index, and dough 8 min integral of Pina-D1a/Pinb-D1p, the starch breakdown of Pina-D1b/Pinb-D1b, and the grain protein content, flour yield, and flour wet gluten content of Pina-D1b/Pinb-D1p were significantly higher than those of other genotype combinations (P<0.05 or P<0.01). The effect of Pins genes on processing qualities of Xinjiang hand-stretched noodles: the stretch feeling, viscoelasticity, and total score of Pina-D1a were significantly lower than those of Pina-D1b (P<0.01). The stretch feeling of Pina-D1b/Pinb-D1p was significantly higher than those of other genotype combinations (P<0.01). The viscoelasticity of Pina-D1a/Pinb-D1p, Pina-D1b/ Pinb-D1a, and Pina-D1b/Pinb-D1b were significantly higher than those of other genotype combinations (P<0.05). The total score of Pina-D1b/Pinb-D1a and Pina-D1b/Pinb-D1b were significantly higher than those of other genotype combinations (P<0.01). 【Conclusion】 The mutation of Pina gene can significantly (P<0.05) increase the grain hardness and the total score of Xinjiang hand-stretched noodles. But the mutation of Pinb gene had no significant effect on the processing qualities of Xinjiang hand-stretched noodles. Pina-D1b/Pinb-D1a and Pina-D1b/Pinb-D1b are the key genotype combinations of high quality breeding for Xinjiang hand-stretched noodles.
