    Trees, tree genetic diversity and the livelihoods of rural communities in the tropics
    State of the World’s Forest Genetic Resources – Thematic study
    2020
    Also available in:
    No results found.

    This study, prepared within the ambit of The State of the World’s Forest Genetic Resources, reviews what is known about the value of trees for tropical rural communities. It focuses on non-timber products harvested from trees in natural and managed forests and woodlands, the various products and services obtained from trees planted or retained in agroforestry systems, and the commercial products of tree commodity crops. The role of intra-specific genetic variation in determining the value of trees in supporting livelihoods is discussed in each of the three contexts. The study also identifies specific points that should be given particular attention in the future to better support tree-based livelihoods of rural communities in the tropics.

    Tricholoma matsutake (pine mushroom) has been a very import mushroom harvested from Pinus densiflora forests for a long time in Korea. Research on matsutake infected-pine trees began at National Institute of Forest Science in 1980. The main objectives of the research were the production of matsutake-infected pine trees in pine mushroom forests and their transplantation in pine forests without pine mushrooms. Although the production of matsutake-infected pine trees was successful, continuous growth of matsutake mycelia from matsutake-infected pine trees and production of fruiting bodies were not achieved after transplantation. The same study started again in 2000 and we tried to find out what the senior researchers had overlooked and cause of failure in their studies. Our main goals of research were (1) the production of matsutake-infected pine trees that minimized the damage of existing fairy ring of T. matsutake, (2) transplantation and confirmation of mycelial growth without damage of existing living matsutake mycelia, and (3) monitoring of fruiting body and management of matsutake pine forest. 150 matsutake-infected pine trees were transplanted into the Hongcheon experiment site from 2001 to 2004. In 2010, the matsutake mushroom was first successfully fruited in a place where matsutake-infected pine trees were transplanted. From 2017 to 2020, fruit bodies of pine mushroom are fruited every year. 21 fruiting bodies occurred in the same site in 2020. It was genetically confirmed that the fruiting bodies in the production area of existing ​matsutake-infected pine trees were identical to matsutake fruiting bodies occurred in the transplanted area using the SSR markers. In conclusion, we established the matsutake cultivation method using matsutake-infected pine trees through tracing the growth of matsutake mycelium, mushroom production, and confirmed it via the analysis of fruiting bodies based on genetic markers.

    At its 15th Regular Session held in Rome in 2015, the Commission on Genetic Resources for Food and Agriculture requested FAO to develop and finalize a thematic study on “Incorporating genetic diversity and indicators into statistics and monitoring of farmed aquatic species and their wild relatives.” The following report includes the discussions and outputs of an expert group that addressed the topic, Incorporating genetic diversity and indicators into regular statistics and monitoring of farmed aquatic species and their wild relatives
