“…Irrigation scheme and frequency also highly affects oil content and composition ( Kadkhodaie et al., 2014 ) which needs further study in the study areas. Sesame seed yield is also very low even under rainfed condition in Ethiopia as reported by ( Baraki and Berhe, 2019 ) 650 kg/ha ( Daba et al., 2014 ); 645–881 kg/ha ( Gebregergis et al., 2018 ); 651 kg/ha and ( Mekonnen and Mohammed, 2009 ) 559.2 kg/ha and this is associated to erratic rainfall, low yielding varieties, diseases and insect pest infestation and poor management. This indicates the productivity of all the sesame genotypes used in this study are superior to many other varieties under different managements in Ethiopia.…”

Sesame production under irrigation is limited in Ethiopia because of in availability of high yielding varieties, inadequate and inefficient irrigation schemes, and insignificant awareness of producers. This study, comprising 13 sesame genotypes, was conducted around Humera and Werer during 2018 and 2019 under irrigation. The design was randomized completely block design with three replications and the objectives were to develop high yielding genotypes and identify important agronomic traits. Multivariate statistical methods like Additive Main Effect and Multiplicative Interaction (AMMI) model, Principal Component Analysis, Cluster and factor analyses were used. The genotypes (6.22%), environments (42.62) and Genotype × Environment Interactions (25.09%) were statistically (p < 0.001) significant for the agronomic traits. The grain yield in each observation varied from 383 kg/ha to 2044 kg/ha and the grand mean yield was 820.19 kg/ha. The highest mean yield was recorded from G12 (948.6 kg/ha) followed by G4 (938.9 kg/ha) while the lowest was recorded from G8 (703.1 kg/ha). G1, G4, G12, G5, G8, G11 and G13 are identified as unstable genotypes while G2, G3, G6, and G9 are stable genotypes. The genotypes were grouped in to four clusters and cluster-II was characterized as the high yielding cluster and it was also associated with grain yield, pods per plant, branches per plant and thousand seed weight. Branches per plant, pods per plant and thousand seed weight may be most determinant and crucial in developing high yielding sesame varieties. This finding recommends that G4 and G6 are desirable genotypes and can be used for irrigation production.

“…To produce quality seed, improved genetic purity is the primary criteria to yield the inherent potential of improved genotypes. It is not questionable that one factor constraining quality seed production in Ethiopia, particularly in Humera, is a lack of characterized sesame varieties [11]. Seedling and plant are the most widely used methods to identify varietal characteristics based on morphological features.…”

Introduction: The experiments were conducted to identify and group sesame genotypes by morphological and genetic characteristics. Materials and Methods: Ten nationally released sesame genotypes were obtained from Humera and Melka-Worer research centers and planted at Humera experimental sites. The number of primary branches per plant was found higher (5.93) for M-80. However, the number of nodes per plant was grouped as ‘more’ (24.13) for M-80 compared to Humera-1, which was grouped as the ‘highest’ (26.13). Plant height was tall in all the sesame genotypes studied. Likewise, the number of nodes per plant in all the genotypes was grouped as more nodes per plant i.e. greater than 15. The leaf length ranged from 7.769 cm to 6.67 cm and genotypes, Argene and K-74 had the lowest and the highest values, respectively. The variation was least in qualitative characteristics like flower colour, number of locules per pod, pod pubescence, and type of pod beak. Thousand seed weight and seed yield per kg per ha had a significance level at P=0.05. Pod length was found to be varied among the genotypes and grouped as ‘long “with a mean pod length of 2.44 cm. Hence, genotypes having a long pod length might be preferred for seed production. The genetic characters of the genotypes were characterized and the level of polymorphism for the selected primers ranged from 56.25% to 100%. ISSR-880 was found with the least level of polymorphism while the other three (ISSR-811, ISSR-812 and ISSR-860,) were found with a high level of polymorphism. Five sesame genotypes (ADI, Humera1, Serkamo, M-80 and E) were clustered and grouped together, while three genotypes, namely, Argena, K-74, and S-Breeder appeared to have their own cluster separately. Results: Our study indicates that agro-morphological and genetic characterization of genotypes is useful and effective in determining polymorphisms in the sesame genotypes molecular genotyping, reproducible and it can also produce enough polymorphism to cluster and identify the genotypes. Conclusion: The findings presented in this paper may prove useful in the future to include more ISSR markers and induvial genotype investigation for detailed characterization of sesame germplasm that would be important for future breeding and sesame improvement program.

“…However, the productivity of the available released sesame varieties so far is lower than some of the producing countries. In moisture stress areas of Western Tigray (Humera), Northern Ethiopia, different genotypes of sesame were evaluated to identify highyielding with desirable agronomic traits in different growing seasons (Baraki & Berhe, 2019). However, there is limited study on the evaluation of sesame genotypes for high yielder and resistance/tolerance to bacterial blight disease in optimum moisture areas of western Tigray, Ethiopia.…”

Ethiopia is one of the major producers of sesame in sub-Saharan Africa, and Ethiopian sesame particularly the whitish Humera type is among the highest quality in the world. However, the yield is lower than some of the producing countries due to many factors including low yielding varieties and bacterial blight disease severities. This study was conducted with the objective of evaluating sesame genotypes for yield and bacterial blight disease resistance during 2017/18 -2018/19 main cropping seasons at Dansha, Ethiopia. Sixteen sesame genotypes were evaluated with one local variety in randomized complete block design (RCBD) with three replications under hot spot area for bacterial blight disease infection. There was significant (P < 0.05) difference among the genotypes for yield, yield-related traits and bacterial blight disease severity. Higher seed yield was recorded in genotype WARC-063 (716.2 kg) with a mean yield advantage of 24.3% over the standard check Humera-1 whereas the lowest seed yield was ABOUT THE AUTHORS Weres Negash Golla (Mr) is a researcher in Tigray Agricultural Research Institute, Humera Agricultural Research Center.
