- Abstract:
- Two crosses F1 in North China (9514，9518) with strongly heterosis and their parents were studied on the isozyme electrophoresis pattern of peroxidase and esterase in the experiment.The results showed that it was not effective measurement to predict the cucumber heterosis with the isozyme electrophoresis pattern esterase and peroxidase in the cotyledon and seedling stage.It was relatively narrow that the genetic basis of the cucumber after the analysis of the electrophoresis pattern.In the breeding process，it should be possible to select genetic differences in parents of hybrid cucumber，to expand the genetic basis of hybrid progeny，enhance the adaptability to the environment.
