连续三十年应用“三结合”突变育种方法,培育出各种类型的突变体材料1860份,将这些材料归类进行利用,是尽快选育小麦新品种的有效途径。几年来,从分离小麦的单株中筛选出17个具有矮秆、大穗、株型紧凑、中早熟、抗性好的优良株系;对21个综合性状较好的材料进行回交改良,对不稳定的突变体材料重点选择,选育出11个综合性状优良的小麦新品系,为快出品种奠定了良好的基础。 For 30 years in succession, “3 combination” mutation breeding method was used to breed 1860 mutant materials of various types. Using these materials for classification and utilization is an effective way to breed new wheat varieties as soon as possible. In recent years, 17 fine lines with dwarf, large spike, compact plant type, early maturity and good resistance were screened out from the individual plants isolated from wheat. Back-cross modification was performed on 21 composite materials with good comprehensive characters, Eleven wheat lines with excellent comprehensive traits were bred for the selection of unstable mutants, which laid a good foundation for the rapid emergence of varieties.
