In vitro plant regeneration from leaf and cotyledon explants of Cucumis melo L

Five different genotypes from in vitro as well as greenhouse grown melon plants were shown to be highly responsive for in vitro shoot formation from leaf explants when placed on basic MS medium supplemented with 1 mg/l 6-benzylaminopurine. In addition, a very suitable regeneration system was obtained when cotyledon pieces of mature seeds were incubated on the same culture medium. In this case, the first shoots already appeared after 10 days of incubation, and hundreds of shoots were formed on the cut surface 3 to 4 weeks later. Explants from mature cotyledons derived from seedlings did not lead to any shoot formation.
