1An Improved New Cultivar of Spring Wheat Bred by Heavy Ion Beams with Medium Energy-'Longfu 2'显示文摘75 MeV/u oxygen ion (^16O+8) beams supplied by HIRFL were used to irradiate 14615 of spring wheat dry seeds of stable multi-generation. Range of the ions in the seeds is about 11 mm. They can enter the seed from its embryo, come out from its top, and penetrate through an entire grain of wheat, length of which is about 6~7 mm. The seeds were vertically inserted in a sample plate of 4 cm in diameter, which can contain about 100 grain of the seeds. During irradiation, the embryo of the seeds faced to ion beams and was irradiated at normal temperature and atmosphere. Irradiation dose was arranged in 1×10^7, 5×10^7, 1×10^8, 2×10^8 and 5×10^8 ions/cm^2 with dose rate of about 3 Gy/min. A part of the irradiated seeds was employed for cytology examination in laboratory, the others were used for breeding in the fields.XieHongmei WeiZengquan WangHaohan LiuQin ZhaoLianzhi LiWenjian LiQiang WangJufang ZhouGuangming DangBingron 2003近代物理研究所和兰州重离子加速器实验室年报:英文版2003,,1:0
