“…Several earlier pieces of research also confirmed the existence of genotypic variations among wheat genotypes for agronomic parameters at various experimental conditions for a number of reasons (Purchase et al 2000;Wiśniewska et al 2004;Buerstmayr et al 2008;Šíp et al 2011;Cazal-Martínez et al 2020). Furthermore, tested genotypes produce a comparatively higher overall mean yield at Bonke and Chencha than others.…”

“…The results pointed out the inconsistency in genotypes' response to FHB, and a single genotype could not be advised for cultivation across environments. In wheat resistance breeding for FHB, tests of genotype performance across a broad range of agro-ecologies (environments) are considered to lessen the influence of GEI, ensuring that the nominated genotypes keep stable resistance against FHB coupled with high-yield performance across many environments (Buerstmayr et al 2008;Šíp et al 2011;Beres et al 2018;Cazal-Martínez et al 2020).…”

Fusarium head blight (FHB) is one of the major biotic constraints to wheat due to its direct detrimental effects on yield quality and quantity. To manage the disease, the deployment of resistant genotypes is ideal in terms of effectiveness, eco-friendliness, and sustainability of production. The study was conducted to determine the responses of different wheat genotypes to FHB, and to identify suitable and stable wheat genotype(s) regarding the FHB resistance and yield performance. A field study was carried out using eleven bread wheat genotypes in seven locations in southern Ethiopia during the 2019 main cropping season. A randomized complete block design with three-time replicates was applied in this study. The results showed that the lowest mean FHB severity (11.33%) and highest mean yield (4.54 t/ha) were recorded at Bonke. Conversely, the highest mean FHB severity (83.38%) and the lowest mean yield (0.94 t/ha) were observed at North Ari. It was also showed that maximum mean FHB severity (49.25%) and minimum mean yield (2.95 t/ha) were recorded on the genotype Hidase under crosswise assessment. Across locations, a minimum mean FHB severity (17.54, 18.83, and 21.31%) and maximum mean yield (3.92, 3.96, and 3.93 t/ha) were noted from the Shorima, Bondena, and Wane genotypes, respectively. GGE biplot analysis and various comparison tests for FHB severity revealed a higher percentage of variation concerning FHB resistance reactions due to the environment (47% as an interactive element), followed by genotype by environment interaction (21%). AMMI analysis revealed genotype, environment, and genotype by environment interaction had a total variation of 7.10, 58.20, and 17.90% for yield performance, respectively. The inconsistency between genotype responses to FHB and yield performance demonstrated that the environmental component was responsible for significant variability in FHB reaction, yield performance, and the dominance of cross-over interaction. However, the greatest level of resistance to FHB was comparatively found in the genotypes Shorima, Bondena, Wane, and Huluka across locations. Considering both FHB resistance response and yield stability, in most environments, Shorima, Bondena, Wane, and Huluka genotypes were suggested for consideration of cultivation where they are well-performed under the pressure of FHB. North Ari and Hulbareg were acknowledged as more discriminating environments than the others for test genotypes against FHB. Bonke and Chencha were considered ideal environments for selecting superior genotypes with good yield performance.

“…Correspondingly, Šíp et al. (2011) reported all isolates and the mixture of F. graminearum isolates detected the lowest values of all traits in the moderately resistant cultivar; however, there were obvious differences among isolates in the ability to detect significant differences among varieties that differ greatly in FHB resistance. On the other hand, Goswami and Kistler (2005) reported significant variation among the strains of F. graminearum species in their ability to cause FHB on wheat.…”

“…On the other hand, Goswami and Kistler (2005) reported significant variation among the strains of F. graminearum species in their ability to cause FHB on wheat. The carefully selected mixture of isolates with varying properties is an alternative to the parallel use of specific isolates, which could bring tests closer to natural infections while lowering costs (Šíp et al., 2011). From our findings, no complete resistance reaction was observed in any of the varieties evaluated.…”

Fusarium head blight (FHB) is a devastating disease reduces wheat yield and quality. This study was aimed to evaluate wheat varieties' responses to spray inoculation with Fusarium graminearum mixture isolates under greenhouse conditions. The treatments were laid out in a randomized completely block design with three replications using 24 bread wheat varieties registered in Ethiopia. The varieties inoculated with mixed inoculum derived from four pathogenic isolates of F. graminearum that had been isolated from wheat kernels. Disease severity was evaluated using a 1–9 scale based on the proportion of bleached spikelets, and the area under disease progress curve (AUDPC) was determined from the disease severity data. At harvest, the kernel weight reduction was determined in comparison to the control. The evaluated traits were significantly interrelated and showed high and significant variation among (p < 0.0001) wheat varieties. Disease severity index among the varieties varied from 29% to 72%, while AUDPC varied from 326%‐ to 1010%‐days. The disease progress rate of the Kingbird variety inoculated with F. graminearum was the slowest (0.0191 units day−1), whereas Ogolcho had the fastest disease progression rate (0.0581 units day−1). Kingbird, Wane, and Limu were moderately resistant, with lower disease severity, AUDPC, and a reduction in 1000‐grain weight and grain weight per spike. Dereselgne, Dambal, and Ogolcho varieties were highly susceptible, with the greatest grain weight per spike reduction (53.2%, 41.4%, and 37.4%) and 1000‐grain weight reduction (41.5%, 42.8%, and 37.5%), respectively. The results implied that there were different levels of FHB resistance in Ethiopian bread wheat varieties. Although current greenhouse evaluation of varieties gives encouraging results, field testing is required to confirm the current findings.

“…Because field trials of woody ornamentals require a great deal of space and effort, a screening method in a seedling stage is beneficial. Examples of the use of such screening are found in several crops, such as maize (Mesterhazy, Lemmens, & Reis, 2012), wheat (Sip, Chrpova, & Stockova, 2011) and also in some ornamentals such as roses (Leus, Huylenbroeck, Bockstaele, & Höfte, 2008), Anthurium (Elibox & Umaharan, 2008) and Rhododendron (Van Huylenbroeck, Calsyn, Keyser, & Luypaert, 2015).…”

Box blight is a widespread disease of Buxus caused by the pathogen Calonectria pseudonaviculata. It is responsible for significant losses in nurseries, gardens and wild boxwood populations. Our goal was to maximize the efficiency of a breeding programme towards increased disease resistance. The use of artificial inoculation of young F1 seedlings with C. pseudonaviculata spores under greenhouse conditions appeared to be a reliable tool for early selection of interesting prebreeding material. Overall, the four hybrid populations screened showed a segregating behaviour between their parents when determining the percentage of diseased leaves and lesion diameter. Genotypes were also found with an increased tolerance as compared to the parental species. Approximately 50% of the seedlings had the same score for both parameters after artificial inoculation in the greenhouse and in the field. Of the seedlings that showed severe symptoms in the greenhouse, <15% showed no disease symptoms in the field. Therefore, for larger breeding programmes, we propose a two‐step selection procedure: first artificial inoculation at seedling level to eliminate all genotypes with severe symptoms and then evaluation of the remaining seedlings in the field. Using this strategy, we were able to select several genotypes in our four hybrid populations with improved resistance to C. pseudonaviculata.
