ارتباط ایزوزیم‌های پراکسیداز با برخی صفات یونجه

12 half-sib families of alfalfa resulted from polycross nursery, were studied in Agricultural Research Station of University of Tabriz. Thirty five individuals of each family were grown in separate pots in the from of completely randomized design at field conditions and analyzed for enzymatic system by slab acrylamide gels. statistical analysis of different data showed that there were a significant relationships between peroxidase and seedling traits. In addition the presence of a band increased mean values of related traits. Furthermore POX-4 isozyme showed a significant relationship with leaf weight. Thus it may be possible to use these enzymes as markers to select alfalfa genotypes in the early breeding stages after the stability of here markers were verified in other experiments.
