ABSTRACT: Mutation breeding by Ethylmethylsulfone (EMS) has
several advantages: high mutation ratio, many mutated phenotypes and low
destruction which has been widely applied for crop breeding. We traced to
uncover the mutagenic effect of EMS to Huangzhou radish by observation on germination
ratio, root length and agronomic traits in field after
soaking radish seeds by different concentration of EMS. In
aspect of low germination ratio and short root length, the growth of radish is
inhibited as the increasing concentration of EMS (from 0.2% to 2%) which
indicates the inhibited effect of EMS to “Huangzhou” radish.
Furthermore, the suitable concentration of EMS for “Huangzhou” radish is 0.4%-
0.8% according to the selection criteria of 50% lethal concentration. The field traits are
recorded after the seed of “Huangzhou” treated by 0.5% EMS. Some agronomic
traits on treated group were found including thickened taproots by compared
with CK.
