Abstract: The vernalizatioin gene in wheat cultivar Shimai 12 (Triticum aestivum L.) was investigated to find a more efficient way for the improvement of growth habit of wheat cultivars grown in Yellow and Huai River Reaches.In the F 2:3 lines derived from the cross between Shimai 12 and Shijiazhuang 8 (a winter wheat cultivar), the ratio of the spring, segregating, and winter lines was in accordance to 1:2:1 based on chi-square test, showing that the spring growth habit of Shimai 12 was determined by single dominant gene, which was identified as Vrn-D1 by gene-specific markers.The Vrn-D1 gene-specific marker was further used to genotype the F 2:3 lines, and the results were consistent with phenotyping, verifying the available utilization of the marker assisted selection for Vrn-D1 in breeding programs.Besides, summer sowing in high altitude and cool area proved to be a cost-saving and efficient method for wheat growth habit identification.
