Abstract: Huai’an is located in the boundary (33°33′ N) of north-south climate in our country, days of winter below 5℃ is over 112 days, all winter wheat varieties can vernalized safely, average temperature in January is over 0.2℃, spring wheat varieties can live through the winter safely. After years of research and practice, we carried out research on winter-spring recurrent selection wheat through Taigu genic male sterile wheat and dwarf-male sterile wheat in Huai’an, and formed a small investment, high efficiency of wheat breeding system through the superiority of the winter-spring wheat hybridization, recurrent selection and shuttle breeding combination, and cultivated a series of new wheat varieties, we opened a new way to improve the efficiency of wheat breeding success. We summarized the progress of recurrent selection wheat breeding in our country, we focus on solving the conflict among the late sowing, early maturity and high yield; construction of Scab Resistant recurrent selection population, create excellent Scab Resistant resources; inducing haploid breeding of wheat with recurrent selection population; strengthen cooperation with foreign research institutions, introducing foreign high-quality germplasm resources, and introducing genetic diversity of populations; and strengthen the cooperation with dwarf –male sterile wheat breeding system, so we can cultivate a series of new wheat varieties with wide adaptability, good comprehensive characters.
