Abstract As an important factor that affects the spike number per unit area of wheat (Triticum aestivum), spike number per plant (SNPP) is sensitive to nitrogen level. In order to detect loci of SNPP response to nitrogen stress and to assist selecting and improving the nitrogen use efficiency or nitrogen stress sustain ability of wheat varieties, genome wide association study (GWAS) was conducted. The association panel consisted of 132 wheat varieties and their advanced lines derived from the north Yellow and Huai Valley Wheat Region of China. SNPP in 8 environments under 2 different nitrogen levels and tolerant index (TI) of SNPP to low nitrogen stress were investigated. Affymetrix Wheat 55K SNP was used to achieved the genetic data. Finally, 4 loci were identified to associated with SNPP in two or more environments accounting for 10.20%~17.5% of the phenotypic variation. And 3 loci associated with TI of SNPP were detected in 2 environments with the phenotypic variation ranging from 11.4% to 16.3%. Evaluation of the genetic effects and frequency of the alleles in the significantly associated loci suggested that it was important to strengthen the selection of the AX-108733649-2B, AX-108889870-4A, AX-111667100-5B and AX-111039914-7D loci for genetic improvement of wheat varieties with high nitrogen use efficiency.
