摘要: 以黄淮海麦区261个小麦品种为材料,分析TaARE1-A基因等位变异与小麦产量相关性状之间的关系,以期获得对提高氮素利用效率、增加小麦产量有重要作用的优异等位变异类型,为小麦分子标记辅助育种提供新的基因资源。结果表明,在67个地方品种中,59个品种为TaARE1-A-a基因型,其余8个品种为TaARE1-A-b基因型;在194个现代品种中,184个品种为TaARE1-A-a基因型,其余10个品种为TaARE1-A-b基因型。在261个小麦品种中,基因型为TaARE1-A-a的小麦品种的千粒质量、粒长、籽粒周长均显著高于基因型为TaARE1-A-b的小麦品种,穗长、每穗小穗数、穗粒数、粒宽、粒长/粒宽在2种基因型中均无显著差异。综上,TaARE1-A-a基因型可增加小麦粒长、籽粒周长和千粒质量,是一种优良的基因型。

Abstract: The relationship between TaARE1‑A allelic variant and yield‐related traits was analyzed with 261 wheat cultivars as materials in Huang‐Huai wheat regions,so as to obtain the superior genotype to improve the nitrogen use efficiency and yield of wheat,and provide new gene resource for molecular marker‐assisted breeding in wheat.The results showed that 59 and 8 of 67 landraces belonged to TaARE1‑A‑a and TaARE1‑A‑b genotypes,and 184 and 10 of 194 modern cultivars belonged to TaARE1‑A‑a and TaARE1‑A‑b genotypes,respectively.In 261 wheat cultivars,thousand‐kernel weight,kernel length and kernel circumference of wheat cultivars with TaARE1‑A‑a genotype were significantly higher than those of wheat cultivars with TaARE1‑A‑b genotype,spike length,spikelet number per spike,kernel number per spike,kernel width and kernel length/kernel width did not show a significant difference between cultivars with TaARE1‑A‑a genotype and cultivars with TaARE1‑A‑b genotype.In summary,TaARE1‑A‑a genotype can increase kernel length,kernel circumference and thousand‐kernel weight of wheat,and is a superior genotype.
