Evaluation of the Performance of Sesame (Sesamum indicum L.) Genotypes Using Multivariate Analysis in Eastern Ethiopia

Abstract

Sesame is a cash crop as well as an oil, food and feed source. The production of sesame in Ethiopia has a lot of potential, but the average seed yield is very low due to the lack of improved high-yielding varieties. Eleven sesame genotypes, including a check (Tate), were tested using a randomized complete block design with three replications over three main seasons (2012/13, 2013/14 and 2014/15) at three sesame growing locations, namely Werer, Arage and Mieso. Based on GGEbiplot and various multivariate analyses of grain yield and related data; genotypes G10 (Acc-051-02-sel-1-(2)), G3 (Serkamo white) and G4 (Acc-051-02-sel-(1)) outperformed the standard check in terms of mean yield and stability. The study was discovered that G10 (Acc-051-02-sel-1-(2)) beat the other sesame genotypes, and thus this genotype was validated. Finally, genotype G10 (Acc-051-02-sel-1-(2)) was proposed by the national variety-releasing technical committee. Further this genotype by the standing committee; and registered in March 2017 by the given name of “Ado”. The main advantages of Ado over the other tested genotypes; it’s with white seed color and 15.9% yield advantage over the check ‘’Tate’’. Furthermore, it was anticipated that because of its seed color, Ado will be commended for high external market preferences and prices, and thereby contribute to the future sesame export market.
