“…Efforts to convert progeny test plots into seed orchards are strongly supported by information on the genetic diversity of Mother plants (0.304). The results of the evaluation of mating system in the progeny test plots showed that T. sinensis tended to engage in outcrossing (93.6%), inbreeding (17.2%) and selfing (6.1%) [30,32] respectively. The species with high degree of hybridization should be able to maintain their genetic diversity [30,32].…”

This research was conducted to investigate the need for a breeding strategy for Toona sinensis Roem. The initial section examined the assessment of the foundational population derived from community forests during the years 2006–2008. This included an evaluation of genetic diversity, mating system analysis, and the estimation of parameter values for genetic growth. Therefore, the primary aim of T. sinensis breeding program was to enhance productivity. To achieve this goal, fundamental requirements were identified for devising a breeding approach for T. sinensis. The second section discussed the assessment of six key areas, namely (1) breeding goals, (2) access to fundamental and breeding populations, (3) selection and enhancement, (4) genetic testing, (5) family relationship management, and (6) reproduction. The results showed that a considerable influence was exerted on the efficacy of the selection. Furthermore, the importance of formulating clear and focused objectives was analyzed with an emphasis on one or two specific aims. It was crucial to acquire a comprehensive understanding of reproductive biology, gene activity, and the interplay between genotype and environmental factors. Suggestions for T. sinensis included formulation of a breeding strategy, establishment of a dedicated breeding population, creation of seed orchards, distribution of high-quality seeds, and enhancement of productivity within community forests.

In terms of their anatomy, there is confusion in differentiating between Toona sinensis (Juss.) Roem. and Toona sureni (Blume) Merr. In order to validate the identification of both species, reconfirmation of the primary character differences is required. The objectives of this study are the reconfirmation of the anatomical properties to confirm their differences and the evaluation of the fiber morphology in terms of pulp and paper raw material quality. The results show that there were differences in the gross physical features of the bark and the color of the wood. The wood color of T. sinensis is red-brown and darker, while T. sureni is white-yellow, leading to the nomenclature red and white surian, respectively. An anatomical view of T. sinensis shows that the annual growth ring has indistinct boundaries as a primary distinguishing anatomical feature, while T. sureni shows that the annual growth ring boundaries are distinct. The annual growth ring allows the establishment of intra-annual past and present structure-function relationships as well as its sensitivity to environmental variability. Based on the results, both species have different anatomical properties, and both species are suitable to be used as a raw material for pulp and paper production.

The ex-situ conservation of Toona sinensis and Toona sureni or surian weren’t supported list threatened species threat but by reduction of huge trees and leaving only small trees that are identical with the reduction of their genetic potential. Genetic potential plays a crucial role within the development of basic and breeding populations. The existence of the 15-year ex-situ conservation plot requires evaluation for simpler management to extend conservation value. The conservation area has collected genetic material from 52 populations from various islands in Indonesia and the progeny test area by testing 100 families from 10 selected populations because the basic source for assembling selected genetic material to supply superior seeds. Currently, genetic material from surian ex-situ conservation has been wont to develop genetic tests that are converted into seed orchards. Limitations of ex-situ conservation include maintenance of genetic material in artificial habitats, decreased genetic diversity, depression of close relative mating, adaptation to climate stress, and the potential for accumulation of weak alleles.it’s many constraints in terms of personnel, costs, and reliance on electrical power sources. supported the challenges within the future, efforts are needed to revamp through the unification of ex-situ conservation and progeny test management to support breeding population development. Strengthening the ex-situ conservation value of T. sinensis & T. sureni can be optimalization through solving all identified challenges and strengthening long-term management.
