Study On Characters Of The Male Sterile Offsprings Of Transformation Wheat Assisted By Ion Beam

Using the male sterile variant offsprings of the transformation wheat, induced by ion beam implantation as materials, the type specification, characters of the infertility and its application value were studied. As for sterility characters, the relationship between sterility and protein quality or plant height was discussed individually, moreover, in order to distinguish its relationship with quality on the protein levels , the differences of the sterility and the fertility between glutenin and gliadin was discussed. To application value on wheat breeding, using sterility on the cultivating breeding directly, the results of two generations were studied. At the same time, other application tools and prospects based on sterility characters were discussed. The main results were as follows:1 As for sterility specification, its inheritance, sterility traits were discussed .The results showed that: the male sterility could be inherited and used in the fields, with a single dominance nucleus gene controlling the male sterile trait.2 Sterility was related to plant agriculture traits and sterility plants was found easily. The study on three wheat agriculture traits of plant height, spike number and spike length, between the sterility and the fertility, showed that both height and spike number was significant extremely. On the average, compared to the fertility, plant height was lower 15.34cm, spike number was less 2.50. As for protein content, the sterility plants were higher, and with the generation, the difference became more distinguished. The variance of the plant height was controlled by single dominance low gene. To the sterility plants, when germination in the lab, Seeding height was far lower, growth potential was more slowly, and roots' activity was more inactively, than the same traits of the sterility plants. individually. These characters could be previewed whether sterile...
