Tropical clump woody bamboo (TCWB) is a kind of high-value forest tree, and China's Yunnan Provence is among the regions with the most tropical bamboos in the world. For a long time, however, the studies on systematic provenance selection has not been implemented for many TCWBs with large-scale cultivation in Yunnan. Therefore, many high-quality provenances still need a urgent excavation and protection. In this study, 39 typical natural or cultivated populations from four TCWBs in Yunnan, i.e., Dendrocalamus sinicus Chia et J. L. Sun, D. giganteus Munro, D. brandisii (Munro) Kurz and D. membranaceus Munro, were surveyed and analyzed with genetic differentiation at population level. Furthermore, combining with average diameter at the breast height (DBH) and weight of culms at population level, the best provenances of those four TCWBs were estimated. The results showed that the average DBH and weight of culms at population level were significantly different among populations of all the four TCWB. Meanwhile, a high level of genetic differentiation was detected among populations of three cultivated TCWBs, i.e., D. sinicus, D. giganteus and D. brandisii, with a high coefficient of genetic differentiation among populations (Gst) which was greater than 0.83. On the other hand, a low genetic differentiation (Gst=0.252 4) was found among populations of D. membranaceus. The results are of great significance for high-quality provenances selection for those four TCWBs.

Abstract: Tropical clump woody bamboo (TCWB) is a kind of high-value forest tree, and China's Yunnan Provence is among the regions with the most tropical bamboos in the world. For a long time, however, the studies on systematic provenance selection has not been implemented for many TCWBs with large-scale cultivation in Yunnan. Therefore, many high-quality provenances still need a urgent excavation and protection. In this study, 39 typical natural or cultivated populations from four TCWBs in Yunnan, i.e., Dendrocalamus sinicus Chia et J. L. Sun, D. giganteus Munro, D. brandisii (Munro) Kurz and D. membranaceus Munro, were surveyed and analyzed with genetic differentiation at population level. Furthermore, combining with average diameter at the breast height (DBH) and weight of culms at population level, the best provenances of those four TCWBs were estimated. The results showed that the average DBH and weight of culms at population level were significantly different among populations of all the four TCWB. Meanwhile, a high level of genetic differentiation was detected among populations of three cultivated TCWBs, i.e., D. sinicus, D. giganteus and D. brandisii, with a high coefficient of genetic differentiation among populations (Gst) which was greater than 0.83. On the other hand, a low genetic differentiation (Gst=0.252 4) was found among populations of D. membranaceus. The results are of great significance for high-quality provenances selection for those four TCWBs.
