Summary:The invention belongs to the field of genetics and discloses a breeding method for new varieties of drought-resistant wheat. Gaocheng 9411 serves as the female parent, ATHLET serves as the male parent, continuous selection is conducted through plant-to-row for generations, and the drought-resistant wheat strains JM205 and JM208 high in waxiness are created; Jimai 22 serves for backcrossing and conducts backcrossing with the drought-resistant wheat strains JM205 and JM208 high in waxiness respectively, six generations of BC6F-5 and BC6F1-8 strains are backcrossed for expanding propagation, waxiness of flag leaves is tested, testing and calculation of physiological indexes about drought resistance are conducted, and the wheat strains J-JM205 and J-JM208 which are high in waxiness, resistant to drought and high in yield are created. According to the breeding method for the new varieties of the drought-resistant wheat, conventional visual inspection conducted at the early stage of backcrossing and index testing c
