Registration of New Sesame (Sesamum indicum L.) Varieties: BaHa-zeyit and BaHa-necho
AbstractImproving seed yield, seed oil content, and other desirable traits is indispensable for sustainable production of the sesame crop. Twelve elite sesame (Sesamum indicum L.) genotypes were evaluated at three locations over two cropping seasons for seed yield and other agronomic traits in a complete randomized block design with three replications. The genotypes evaluated were W-103(WSS), W-104(SSM), W-106(SSM), W-107(WSS), W-109(WSS), W-110(WSM), W-119(WSM), W-120(WSM),
W-122(WSM), W-124(SSM), W-125(SSM), and local check. Two sesame varieties, namely, Abasena and Adi were planted side by side with the 12 accessions for use as standard checks. The inter-row and intrarow
spacing used was 0.40 and 0.10 meters, respectively. BaHa-zeyit (1.3 t ha-1) and BaHa-necho (1.2 t ha-1) were found to be superior in seed yields by 27 and 23% to the respective checks (Abasena and Adi). BaHa-necho is white-seeded, which is preferred for export while BaHa-zeyit is gray-seeded. BaHa-zeyit has high protein (27.1%) and crude oil (56%) contents; such an amount of oil content has not yet been reported for any sesame varieties developed and registered in Ethiopia. Both varieties were found to be
moderately tolerant to bacterial leaf blight. As a result, these two varieties were released for cultivation in 2016, considering their contribution mainly to the improvement of sesame seed, protein, and oil yields. Thus, BaHa-zeyit and BaHa-nacho are sesame varieties released for the first time for East Hararghe Zone in Ethiopia, and can be cultivated in the region and other areas with similar agro-ecologies.
