In order to find a new technique for breeding super high varieties of wheat s, according to the theory that rare gene activity will be caused then make new genotypes, and promote branch and evolution of species in strange radiation fields, and the principle of mutagenic breeding, In order to increase crop yield, it is necessary to improve the physiological metabolic intensity of plants and improve the hybridization advantages in breeding. In order to improve the hetero sis of hybrids, there must be large genetic differences between parents and close to extreme types as far as possible. However, for crops with little genetic difference among wheat and other varieties, it is difficult to develop new varieties with high yield by conventional hybrid breeding. Therefore, by means of radiation mutagenesis, one or two parents of the hybrid can be mutated, which can improve the genetic difference between the parents and enhance the hetero sis of the hybrid parents. For this, we call it "new technology". In this paper, the technology of breeding high varieties directly in progeny with various radiation factors and of F0, F1, F3 by irradiation is called "classical technique.” By comparing "new technology" with "classical technology", this paper introduces the practice and application prospect of the new technology, and introduces the characters, advantages and disadvantages and application value of the super-large grain wheat variety "Long Nan 71a" cultivated by the new technology.
