Vegetative Propagation and Genetic Improvement Of Neem

Neem (Azudirachta indica A. Juss), one of the globally important tree species, grows well in dry areas. The vegetative propagation technique (adventitious ischolar_maining in branch cuttings) has been standardized. 1000 ppm IBA induced 80% ischolar_maining and luxuriant ischolar_main system in branch cuttings of mature trees only in leaf fall season (February). However,juvenile cuttings collected from young seedlings showed ischolar_maining in most of the months. The technique is recommended for mass multiplication of superior trees for establishment of clonal seed orchard and afforestation programmes. No attempt has been made so far on the genetic improvement of the tree. It is emphasized that research on genetics and breeding shall pave the way for commercial exploitation of Neem.
