利用一步正筛选与多步正筛选分别获得了抗病突变体。
One step and multiple steps screen methods were established and banana mutants were obtained.
目的：初步鉴定宽叶菘蓝体细胞无性系植株的抗病突变体。
Objective: To make initial identification on Isatis Indigotica Somatic Clones' resistant mutant.
抗病突变体大多伴随着株高、熟期、育性或粒重等农艺性状的变异。
These mutants were almost accompanied by variations in agronomic traits such as dwarfism, high sterility, heading date or grain weight.
突变体酶的变化比亲本显著，这些变化与它们的抗病性强弱相一致。
The change in degree of activity for mutants was more than that of the parent, and coincident with the ability of resistance to disease.
同时也说明细胞水平的抗病性与植株水平的抗病性不完全对应，但这种突变体筛选途径是切实有效的。
These results also showed that the resistance at the cell level were not always as same as whole plants.
