Abstract

ABSTRACT Teak clonal trial was established at Watusipat, Gunung Kidul to obtain best clonal for fast growth in order to increase productivity of privatelly owned forest of teak (Tectona grandis).  Tirdty one (31) clonal teak from Thailand and teak forest in Java Island and Muna, Sulawesi Tenggara were tested in this trial. Randomized Complete Block Design, consisting of 5 replications, and 5 tree (clone) per plot were designed in this plot. Data of the teak clonal trial were collected for growth (height and diameter at breast height) in 2 and 4 years old.  In view of the variation between clones and genetic variation of growth, the analysis of variance (ANOVA) and genetic parameters were conducted.  The results showed that significant differences were found   between clones in the trial for height and diameter in 2 or 4 years old. The average of height were 5.10 m in 2 years old and 8.88 m in 4 years old, the average of diameter were 5.86 cm in 2 years old and 9.21 cm in 4 years old.  Clonal repeatabilties were low in the trial (H2C=0.07 for height and H2C=0.08 for  diameter in 2 years old; H2C=0.13 for height and H2C=0.12 for diameter in  4 years old). Base on these results, it can be conclued that the breeding program of teak can improve the mean annual increment (MAI) while using clonal selection. Therefore, the main goal for increasing productivity of teak privatelly owned forest, will be achieved. Keywords: Genetic, Clone, Teak,Variation, Growth

Abstract

Uji keturunan Warugunung (Hibiscus macrophyllus) dibangun lokasi lereng Gunung Willys, di Van Dillem, Kabupaten Trennggalek, Jawa Timur. Materi genetik Warugunung berasal dari sebaran hutan rakyat di 7 populasi di Pulau Jawa. Tujuan penelitian ini untuk mengetahui keragaman genetik pertumbuhan dan kinerja famili maupun populasi yang diuji pada tinggat awal pertumbuhan di uji keturunan. Penelitian uji keturunan Warugunung menggunakan rancangan Incomplete Block Designdengan menguji 50 famili dengan 3 pohon setiap plot dan 6 ulangan. Hasil pengukuran umur 6 bulan di analisis dengan Anova dan parameter genetik. Hasil penelitian menunjukkan bahwa uji keturunan Warugunung pada umur 6 bulan telah menunjukan adanya perbedaan tinggi pohon maupun diameter pohon antar populasi secara signifikan. Tanaman Warugunung yang berasal dari Populasi Sodonghilir Padawaras, Tasikmalaya, Jawa Barat mempunyai pertumbuhan tinggi pohon yang terbaik dengan rerata sebesar 81,71 cm dan Tanaman yang berasal dari populasi Banjar, Ciamis, Jawa Barat mempunyai pertumbuhan diameter yang terbesar dengan rerata 0,97 cm. Heritabilitas individu tinggi pohon dan diameter batang termasuk katagori tinggi yaitu h2i=0,87 untuk tinggi pohon dan h2i=0,30 untuk diameter batang. Penelitian pada tahap awal dapat disimpulkan bahwa materi genetik yang diuji mempunyai keragaman genetik pertumbuhan antar famili di dalam populasi maupun antar populasi secara signifikan.
