The breeding program of Melaleuca cajuputi subsp. cajuputi in Indonesia  was started  in 1994 by the Institute for Biotechnology and Forest Tree Improvement in cooperation  with CSIRO-Australia. An assessment  of progeny test of M. cajuputi at Paliyan at  23 months and at Sukun-Ponorogo at 36 months old were conducted to ascertain the  patterns of genetic variation in growth and foliar oil   and to  estimate genetic parameters in growth and foliar oil .  Based on the evaluation, genetic variation on growth and oil yield were high. Genetic gain estimation for growth and oil yield were 11.83 to 20.38 % in the progeny test seedling seed orchard of M. Cajuputi at Sukun, Ponorogo.
