Evaluation of sesame genotypes for seed yield and bacterial blight (Xanthomonas campestris pv. sesami) disease resistance in optimum moisture areas of Western Tigray, Ethiopia

Abstract

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.

The Sesame (&lt;i&gt;Sesamum indicum L.&lt;/i&gt;) Value Chain and Microbiological Quality of Crude Sesame Oil, a Case Study in Western Tigray, Ethiopia

“…Regulatory (8.9%) were from health extension, agricultural specialist to control the use of pesticides, post-harvest technologist and food scientists regulate agro-processing including sesame based products processing. A multi-disciplined researcher (8.2%) with the aim of improving sesame productivity, introducing sesame new breeds and diseases resistances [50], post-harvest handling, and loss reduction, and value addition [47] [51] were involved. Traders (22.2%) include cooperatives, unions and individuals who supply sesame to the global market guided through the Ethiopian commodity exchange office (EXC) (market intermediary, 6.7%) or to the local market.…”
