Abstract

Teak planlets (Tectona grandis) of Salomon clones were irradiated by gamma rays to induce genetic variability for growth improvement. The objectives of this research were to analyze the radiosensitivity of T. grandis Salomon clones by gamma ray irradiation and to analyze the genetic variations using Random Amplified Polymorphic Deoxyribonucleic Acid (RAPD). For those purposes, teak planlets were irradiated using gamma rays at 5 different dosages, those were 0 Gy, 10 Gy, 20 Gy, 30 Gy, and 40 Gy. Lethal doses50 (LD50) and reduced doses50 (RD50) were obtained using Curve-fit Analysis. Furthermore, the irradiated planlets were subcultured on medium MS + 0.1 kinetin (M1V0) the surviving M1V0 plantlets were multiplied to MS + 0.1 kinetin, so it is obtained the M1V1 generation. Genetic variation of the mutant was molecularly analyzed using RAPD methods and the variability was calculated using Analysis of Molecular Variance (AMOVA). Results of this research showed that lethal doses50 (LD50) and reduced doses50 (RD50) values were obtained at 24.5 Gy and 7.85 Gy, respectively. It includes genomes of small size and a small number of genomes. The genetic variation of mutant individuals in among and within the treatment of gamma irradiation was 16% and 84% according to AMOVA. It means that the dominant effect of genetic material caused genetic variation in mutant M1V1 generations. This dominance of genetic material could be caused by the response combination of tissue culture treatment and genetic factors that had the potency to be used as materials to select desired clones in the next stage.

Abstract

In vitro continuous development (proliferation) and growth enhancement of callus, which orginated from irradiated-plantlets of Solomon teak clones, have been sequentially conducted on culture medium of (1) MS + 0.1 ppm kinetin, then transferred to (2) an half-strength MS + 0.1 ppm kinetin + 0.1 ppm BAP + 100 ppm charcoal, to (3) an half-strength MS + 0.1 ppm BAP + 3% sugar and finally to (4) half strength MS + 0.3 ppm BAP + 3% sugar. The objectives of this research were to evaluate the morphogenesis of putative-mutant Solomon teak from generation M1V1 and estimate allele frequencies as well as population heterozygosity in vitro.  Results demonstrated that exposure to gamma irradiation (10, 20, 30, and 40 Gy) in the M1V1 generation induced callus formation within two weeks, followed by the development of embryogenic callus. Genetic analysis revealed low diversity among M1V1 individuals as indicated by Na>Ne and He<Uhe. Gamma irradiation potentially increased both allele number and heterozygosity by approximately 50%. Ten putative-mutant teak seedlings are obtained, these lines should be maintained and propagated as valuable genetic resource for future teak improvement programs
