【摘要】 利用小麦纯系种子进行了硼酸溶液和水处理的航天诱变试验。研究表明,航天处理对种子发芽、出苗和生长有明显的促进作用,第二代农艺性状具有广泛变异,而且正向变异较多,为后代选择提供了更多机遇。经一定的育种程序,选出了5个高产、抗病、优质的小麦新品系,其中97-5199已进入生产试验。更多还原

【Abstract】 Wheat pure lines seeds, which were soaked in water and boric acid solution, were used for space treatment. The result showed that space treatment could obviously promote the germination percentage of sead, seedling emergence and growth in field. High mutation frequency and more positive mutant of main agronomic characters could be found in sp2 generation of space treatment.5 new lines with characters of high yield, good quality and diseases resistance have been bred.更多还原
