“…Menurut Missanjo, Thole, dan Manda (2013), pengendalian gen terhadap pertumbuhan tanaman dimungkinkan berubah seiring dengan pertambahan umur tanaman. Perubahan nilai heritabilitas karena bertambahnya umur terjadi pada beberapa jenis tanaman, diantaranya Acacia mangium (Nirsatmanto, Korinobu, & Shiraishi, 2012), Eucalyptus pellita (Leksono, 2008), Aracaria cunninghamii (Setiadi, 2010;Setiadi & Susanto, 2012) dan Jati/Tectona grandis (Hadiyan, 2009). Proporsi komponen varians genetik yang cukup tinggi juga ditemukan pada tanaman uji keturunan pulai gading (Alstonia scholaris) umur 2 tahun di Gunung Kidul (Mashudi & Baskorowati, 2015) dan Araucaria cunninghamii umur 5 tahun di Bandowoso (Setiadi & Susanto, 2012).…”

“…Upaya mendapatkan benih unggul tanaman jati, telah dilakukan penelitian pemuliaan jati oleh Perhutani, Badan Litbang Kehutanan dan perguruan tinggi (Adinugraha, Pudjiono, & Mahfudz, 2013;Hadiyan, 2009;Siregar, Siregar, Karlinasari, & Yunanto, 2008). Kegiatan yang dilakukan antara lain penelitian uji klon dan uji keturunan jati, pembangunan kebun benih semai, kebun benih klon dan kebun pangkas.…”

Multiplication of teak clones can be conducted by using vegetative methods either macro or in vitro. In this research, several teak clones collected from Gunungkidul and Wonogiri were propagated using bud grafting technique to know the variation of their growth ability in the nursery. This research arranged in nested design, with 25 clones nested in 3 locations of scion source (clonal test at Gunungkidul, progeny test in Gunungkidul and clonal test in Wonogiri). Each treatment was repeated in 5 replications and each replication consisted of 10 bud grafted seedlings. The result showed that there were significant variations of growth among the clones in all observation characters, whereas the location of scion source was not significant. The best survival percentage of bud grafting from 3 sites of scion source were Clone 8 from the clonal test in Gunungkidul, Clone 64 from progeny test in Gunungkidul, Clone 43 and 87 from the clonal test in Wonogiri.

“…Hal ini akan memudahkan pemulia dalam melakukan seleksi. Korelasi genetik antara sifat tinggi dan diameter yang tinggi banyak terjadi pada tanaman kehutanan, antara lain Falcataria moluccana (Ismail dan Hadiyan, 2008;Hadiyan, 2010), Shorea parvifolia (Prasetyawati, 2009), A. cunninghamii (Setiadi, 2010), Tectona grandis (Hadiyan, 2009), dan Intsia bijuga (Mahfudz, 2013). Korelasi yang kuat ini sangat penting dalam kaitannya dengan seleksi yang akan dilaksanakan, karena dengan menyeleksi tinggi tanaman secara tidak langsung akan memperbaiki sifat pertumbuhan diameter.…”

The estimation of genetic parameters for stem diameter and plant height of ironwood (Eusideroxylon zwageri T. et B.) was conducted in a progeny trial in Bondowoso, East Java at the age of 5,5 years. The trial was arranged in an incomplete block design, which comprised of 49 families from three provenances (Batanghari, Berau and Kutai Kertanegara) with 4 replications and single tree plot. Families of Batanghari provenance showed the best growth of stem diameter and plant height compared with another provenance. There was significant difference in plant height between families within provenance, whereas stem diameter was not significantly different both of between provenance as well as between families within one provenance. Non-genetic or environmental factors provide considerable influence on plant growth in the progeny test of ironwood until the age of 5.5 years; it was indicated by the residual variance component. Individual heritability for plant height was considered as high (0.37) and stem diameter was considered as moderate (0.26). There was a strong genetic correlation between the stem diameter and plant height (0.95). This information is very important for future genetic improvement of ironwood.
