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.
