Analysis of offspring of wheat transferred with exogenous DNA by ion beam

Ion beam technology is an effective technique in inducing breeding and transformation.Some valuable wheat variation materials were obtained using ion beams.The agronomic traits,quality traits,seed gliadin of these materials were studied.The results show that the plant height,main stem panicle length,grain weight,leaf traits,protein content,and wet gluten content of the variations have obvious changes compared with the control and reach a significant level.Seeds gliadin bands of the variation materials changed exactly compared with the control,bands changes of some variation materials have been stable,and that of other materials exist polymorphism,which show that the materials are not stable.The results show that ion beam biotechnology can generate all kinds of variations and new germplasm resources.The results provide a theoretical basis for application of ion beam biotechnology in wheat.
