理化诱变与杂交选育结合是近年植物育种技术发展的新趋向,已引起各国植物育种界的普遍重视。我国也已开展了这方面的应用研究。然而,主要是在诱变育种中结合运用有性杂交和诱变处理常规杂合材料。在杂交育种中运用诱变处理手段的为数尚少。扩大两者结合的应用范围,特别是在大规模的杂交育种中扩大对理化诱变手段的应用。将会使植物育种工作获得更大的经济效益。一、杂交选育和诱变育种技术当今所面临的主要育种问题杂交育种能把存在于不同植物、不同品种、不同遗传型的优良性状组合到一个新的 The combination of physical and chemical mutagenesis and breeding is a new trend in the development of plant breeding technology in recent years and it has drawn universal attention in plant breeding circles in various countries. China has also carried out applied research in this field. However, it is mainly the combination of mutagenic breeding using sexual hybridization and mutagenesis to treat conventional hybrid materials. The use of mutagenic methods in hybrid breeding is still small. Expand the scope of application of the combination of the two, especially in the large-scale cross breeding to expand the application of physical and chemical mutagenesis means. Will make plant breeding more economic benefits. First, the hybrid breeding and mutagenesis breeding technology now facing the main breeding problems Cross breeding can exist in different plants, different varieties, different genetic types of fine traits combined to a new
