Abstract

A provenance trial of suren (Toona sinensis Roem) is aimed to obeserve the best provenance in adaptation and growth traits. This provenance is used as seed sources for forest rehabilitation in the area of development. Eleven provenances of suren from Sumatera Island was established in Candiroto, Temanggung, Central Java. The plot was designed in a Randomized Completely Block Design (RCBD) comprised of three replicates, 11 provenances and 9 trees per plot with spacing of 3m x 3m. This study showed that tree height, diameter and volume were significant different among provenances at 4 and 5 years age, while significant for survival at 5 years age. Tree height, diameter and volume showed significant and positive correlation with each other. Broad sense heritability  value were found fairly good for all traits. Pasaman (West Sumatera) provenance is recommended to be the best seed sourced for plantation under similar site conditions and also genetic improvement programme.

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

Genetic parameters were estimated for height and diameter characteristic of Ficus variegata Blume seedlings planted in the nursery of The Centre for Forest Biotechnology and Tree Improvement, Yogyakarta at 8 months of age. The trial involved seedlings from several mother trees (family) originated from Lombok Island. The trial was arranged in a Randomized Complete Block Design (RCBD) which comprised of 17 families as treatment, 3 replications and each replication comprised 10 seedlings. Analysis of varians showed that height and diameter were significantly different between families. Family heritabilities for height and diameter characteristic were 0.98 and 0.91 respectively, while genetic correlation between the two characteristics were 0.7. This information is very important for future genetic improvement of the species.
