Abstract

Three progeny trials of nyawai (Ficus variegata Blume) were established in Mangunan, Bantul, Yogyakarta. The trials were grouped in three sublines based on their original provenances: Lombok, Banyuwangi and Cilacap-Pangandaran. Each subline was laid out in Randomized Completely Block Design (RCBD) comprising 15-19 families.This study was aimed to observe growth variation and genetic parameter of the three sublines progeny trial at six and twelve months after planting. Analysis of variance was made to observe family effect for height and diameter, then the component of variance of each trait was used to estimate the heritability and genetic correlation. The results of study showed that at 12 months of age the survival rate of the trial was more than 90%, indicating high adaptability of the species to the trial site. Family effect on growth traits tended to increase as the trees getting older. Except for diameter in sub-line of Banyuwangi, estimation of individual heritabilities for height and diameter traits ranged from 0.015 to 0.241 and 0.017 to 0.096 respectively, with the corresponding for family heritabilities of height and diameter traits ranged from 0.09 to 0.434 and 0.123 to 0.352 respectively. It suggests that genetic control of the traits at both individual and family level were weak in the early growth. Genetic correlation between the two growth traits were varied among the sub-lines, indicating the character and growth pattern of nyawai seemed to be different among the sub-lines.

Abstract

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.
