Abstract

This  work  had  the  aim  of  comparing  the  method  of  hybridization  with  digoxigenin  and the chemiluminescent detection  system with  the method of  radioactive  labeled. The cultivars used were susceptible Florunner  and  resistant COAN. The genomic DNA was  isolated  from young  leaves  and Southern blotting analysis was conducted using RFLP probe R2430E. The detection of the probe labeled with digoxigenin was as sensitive as labeled by the radioactivity, however with advantages above the method  radioactive. Due  to be a  safe method and  to present  reduced costs,  the demarcation method based on the digoxigenin and chemiluminescent detection is highly recommendable.
