| 1 | Genome-wide association mapping for grain shape and color traits in Ethiopian durum wheat(Triticum turgidum ssp.durum)显示文摘Grain shape and color strongly influence yield and quality of durumwheat.Identifying QTL for these traits is essential for transferring favorable alleles based on selection strategies and breeding objectives.In the present study,192 Ethiopian durum wheat accessions comprising 167 landraces and 25 cultivars were genotyped with a high-density Illumina iSelect 90K singlenucleotide polymorphism(SNP)wheat array to conduct a genome-wide association analysis for grain width(GW),grain length(GL),CIE(Commission Internationale l'Eclairage)L*(brightness),CIE a*(redness),and CIE b*(yellowness)traits.The accessions were planted at Sinana Agricultural Research Center,Ethiopia in the 2015/2016 cropping season in a complete randomized block design with three replications.Twenty homogeneous and healthy seeds per replicate were used for trait measurement.Digital image analysis of seeds with GrainScan software package was used to generate the phenotypic data.Analysis of variance revealed highly significant differences between accessions for all traits.Atotal of 46 quantitative trait loci(QTL)were identified for all traits across all chromosomes.One novelmajor candidate QTL(−lg P≥4)with pleiotropic effects for grain CIE L*(brightness)and CIE a*(redness)was identified on the long armof chromosome 2A.Eighteen nominal QTL(−lg P≥3)and 26 suggestive QTL(−lg P≥2.5)were identified.Pleiotropic QTL influencing both grain shape and color were identified. | Admas Alemu Tileye Feyissa Roberto Tuberosa Marco Maccaferri Giuseppe Sciara Tesfaye Letta Bekele Abeyo | 2020 | The Crop Journal2020，8，5： | 2 |
| 2 | Climate forcing of tree growth in dry Afromontane forest fragments of Northern Ethiopia:evidence from multi-species responses显示文摘Background: Climate-induced challenge remains a growing concern in the dry tropics, threatening carbon sink potential of tropical dry forests. Hence, understanding their responses to the changing climate is of high priority to facilitate sustainable management of the remnant dry forests. In this study, we examined the long-term climate-growth relations of main tree species in the remnant dry Afromontane forests in northern Ethiopia. The aim of this study was to assess the dendrochronological potential of selected dry Afromontane tree species and to study the influence of climatic variables (temperature and rainfall) on radial growth. It was hypothesized that there are potential tree species with discernible annual growth rings owing to the uni-modality of rainfall in the region. Ring width measurements were based on increment core samples and stem discs collected from a total of 106 trees belonging to three tree species (Juniperus procera, Olea europaea p. cuspidate and Podocarpus falcatus). Thesubsp. collected samples were prepared, crossdated, and analyzed using standard dendrochronological methods. The formation of annual growth rings of the study species was verified based on successful crossdatability and by correlating tree-ring widths with rainfall. Results: The results showed that all the sampled tree species form distinct growth boundaries though differences in the distinctiveness were observed among the species. Positive and significant correlations were found between the tree-ring widths and rainfall, implying that rainfall plays a vital role in determining tree growth in the region. The study confirmed the formation of annual growth rings through successful crossdating, thus highlighted the potential applicability of dendroclimatic studies in the region. Conclusions: Overall, the results proved the strong linkage between tree-ring chronologies and climate variability in the study region, which further strengthens the potential of dendrochronological studies developing in Ethiopia, and also has great implications for further paleo-climatic reconstructions and in the restoration of degraded lands. Further knowledge on the growth characteristics of tree species from the region is required to improve the network of tree-ring data and quality of the chronology so as to successfully reconstruct historic environmental changes. | Zenebe Girmay Siyum J.O.Ayoade M.A.Onilude Motuma Tolera Feyissa | 2019 | Forest Ecosystems2019，6，2： | 2 |
