本试验用Co~(60)γ射线处理大花桑和转阁楼桑接穗,得到性状稳定的“辐花77—1”“辐转82—1”突变体,在叶质、节间长度方面优于供试亲本大花桑和转阁楼桑。但由于基因多效应和基因连锁关系,致使在出现有益性状的同时又伴随其它不良性状如:长势不旺,产叶量不高,抗病虫能力弱的发生。通过能量密度35J/cm~2和27.5J/cm~2的钕玻璃
In this experiment, Co ~ (60) γ-rays were used to treat the mulberry spikes of Datong and Luanlou, and the stable mutant “Radix 77-1” and “Spin 82-1” The length of the test is better than the parents of the large flowers mulberry and attic Mulberry. However, due to the gene multi-effect and genetic linkage, resulting in the emergence of beneficial traits at the same time with other undesirable traits such as: growing, leaf yield is not high, the ability to resist pests and diseases. Pass neodymium glass with energy densities of 35 J / cm ~ 2 and 27.5 J / cm ~ 2
