The current study was designed to generate information on genetic variability and inheritance of yield and its component traits using 36 advanced bread wheat lines. Field experiment was conducted in 2018 cropping season at Haramaya and Hirna in eastern Ethiopia using triple lattice design. Fifteen quantitative traits were measured and subjected to analysis of variance and genetic analyses. Analysis of variance revealed that there was highly significant difference among genotypes for all quantitative traits at both locations. The lowest and the highest phenotypic (PCV) and genotypic (GCV) values were obtained for hectoliter weight and number of fertile tillers per plant, respectively at both locations. Heritability in broad sense and genetic advance as percent of mean ranged from 39.1% (number of kernels per spike) to 90.1% (days to heading), and from 2.4% (hectoliter weight) to 48.5% (number of fertile tillers), respectively at Haramaya. At Hirna, these parameters ranged from 29.3% (hectoliter weight) to 91.9% (grain yield), and from 1.5% (hectoliter weight) to 27.6% (total tillers per plant), respectively. high heritability coupled with high genetic advance as percent of mean was observed for total number of tillers per plant, number of fertile tillers per plant, grain yield per hectare, and above ground biomass per hectare at Haramaya. and for spike length, total number of tiller per plant, number of fertile tiller per plant, grain yield per hectare, and above ground biomass per hectare at Hirna. This indicates that improvement of these traits through selection is easier than other traits measured.","PeriodicalId":16806,"journal":{"name":"Journal of Plant Sciences","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89589738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within Ghana's middle belt, five mature trees with identical diameter at breast height were chosen. Mechanical characteristics and basic density were determined in accordance with British Standard BS 373 and ASTMD 2395, respectively. The IAWA list of microscopic features for hardwood identification was followed by anatomical features. Basic density, mechanical, and anatomical parameters all had a positive connection (P<0.05). Branchwood had a little higher basic density than stemwood, and heartwood had a slightly higher basic density than sapwood. There were minor changes in MoE, MoR, compression, shear, and hardness between the heartwood and sapwood. The stem and branch, on the other hand, were comparable. Fibre percentages were higher in stemwood than branchwood and in heartwoods than sapwoods anatomically. There were more vessels in the branch than in the stem, and in the sap than in the heart. The branchwood of N. papaverifera had medium strength qualities that were comparable to most medium construction species' stemwood and could thus be used in addition to their stemwood. The study has offered information on N. papaverifera branchwood that may inspire trust and interest in the use of branchwood as a supplemental material in the manufacture of wood products.","PeriodicalId":16806,"journal":{"name":"Journal of Plant Sciences","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81643229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
