通过辐射处理远缘杂交后代可以引起染色体畸变,出现许多具有染色体结构变异的优良株系。黑麦属对改进六倍体栽培小麦遗传种质具有很大潜力。自1956年Sears报道了通过染色体易位,将外源染色体片断导入
Chromosomal aberrations can be induced by radiation treatment of distant hybrid progeny and many excellent lines with chromosomal structural variations appear. Triticeae have great potential to improve the genetic inheritance of hexaploid cultivated wheat. Since 1956 Sears has reported the introduction of exogenous chromosome segments by chromosomal translocations
