Abstract

Archidendron clypearia (Jack) I. C. Nielsen is an important tree species for traditional medicine purposes such as anti-inflammatory, detoxification, uric acid control and neuro-protection. Here, a set of 15 microsatellite markers were used to fingerprint 248 elite genotypes from six origins of A. clypearia and investigate the genetic structure of these genotypes. A total of 170 alleles were amplified. The elite genotypes showed moderate genetic variability, with mean observed heterozygosity (Ho) and expected heterozygosity (He) being 0.651 and 0.699, respectively. Each of the elite genotypes could be fingerprinted uniquely. The cumulative probability of identity (PI) and the cumulative probability of paternity exclusion (PE) were 2.25 × 10−12 and 0.999992, respectively, demonstrating the extremely high power of the markers for genotype identification. In STRUCTURE and clustering analyses, the same origin of elite genotypes tended to be grouped in a sub-population and clustered closely, but some genotypes from different geographic origins were mixed, suggesting a low level of genetic differentiation between the origins. These results can contribute to the protection and management of the elite genotype resources of A. clypearia and the comprehensive understanding of its genetic structure. [ABSTRACT FROM AUTHOR]

Abstract

Using a cloned Eucalyptus urophylla x E. tereticornis family, the present study estimated clonal mean repeatability, inter-trait correlation, and clone-by-site interactions for height (H) and diameter at breast height (D) across 0.5--8 years of age as well as 8-year-old wood basic density (BD8), cellulose content (CC8), hemi-cellulose content (HC8), Klason lignin content (LC8), and lignin syringyl-to-guaiacyl ratio (S/G8). Clonal mean repeatability estimates were 0.40--0.91 for growth traits H and D over 0.5--8 years and 0.50--0.87 for wood properties at age 8 for three separate sites (except that of 0.01 for HC8 at Yanxi) and across sites, indicating moderate to high levels of genetic control of the traits investigated. H had high positive genetic correlation with D. Growth traits (H and/or D) showed generally positive genetic correlation with BD8 and CC8 while negative with HC8 and LC8. Significant genotype-by-environment (clone-by-site) interactions were observed for most traits, suggesting that clones should be matched to sites to increase genetic gain. Our results suggest that there is potential to use E. urophylla x E. tereticornis clones to increase yield with desirable wood properties in Southern China. [ABSTRACT FROM AUTHOR]
