Fumai 668 is a new, semi-winter wheat variety created by Suqian Institute of Agricultural Sciences, Jiangsu Academy of Agricultural Sciences, in cooperation with Anhui Chuangfu Seed Industry Co., Ltd. Based on the pedigree method, it was bred by cross-fertilization using(Jimai 22/Simai1108) F4 as a maternal parent and Huaimai 18(a high-yielding, multi-spike and medium-maturity wheat variety) as a paternal parent. In regional field trials, Fumai 668 had the whole growth period of 214.7 d, which was shorter than that of the control variety Jimai 22, the plant height of 71.2 cm, a stronger tillering ability, a higher earing rate with about 5.618 million spikes p er hectare, large spikes with the mean grain number of 34.6 grains per spike, and the 1 000-grain weight of 46.5 g. It also showed moderate susceptibility to scab and sheath blight, moderate resistance to powdery mildew and strong comprehensive resistance, as well as high-yielding potential and yellowing well at maturation. Approved by Anhui Provincial Crop Variety Approval Committee in 2021, the new wheat variety is suitable for planting in areas in the north of Huaihe River and along Huaihe River.
