Abstract
Ethiopia has suitable environmental condition for emmer wheat production. However, the productivity of emmer wheat is very low as compared with world average due to lack of stable, improved seed and poor agronomic managements. Therefore, the objective of the study was to evaluate the promising genotypes and verify the most stable, uniform, high yielding and disease resistant emmer wheat for highland areas of Bale. The materials were crossed at Sinana Agricultural Research Center; i.e. emmer wheat crossed with durum to improve yield and thresh ability of emmer wheat. The experiment was carried out at two locations namely Sinana and Goba. Including checks 15 genotypes have been evaluated in three replicated of randomized complete block design (RCBD). The trial was studied for three consecutive years (2013, 2014 and 2015) main cropping seasons. After evaluation of genotypes across location and years, Haydaroo was selected and verified for one year (2016) at multilocation. Haydaroo is a common name given for the newly released emmer wheat variety that a pedigree designation of “Sinana_01 x DZ2212//Sinana_01”. Haydaroo (Sinana_01x DZ2212//Sinana_01) had above average yield performance in most tested environments, out yielded for Sinana-01 and Local check varieties. The mean average grain yield of Haydaroo is 30.24 quintal per hector. It is stabile and uniform across locations. Finally, it was evaluated by National Variety Releasing Committee and recommended for release in 2017 for high lands of Bale and similar agro-ecologies.
Highlights
Emmer (Triticum dicoccum) is amember of the wheat family of annual grasses
Wild emmer is fully compatible with the tetraploid (AABB) durum wheat, it can be crossed with the hexaploid (AABBDD) bread wheat [4], and it harbours wide genetic diversity relevant to the improvement of various economically important traits in cultivated wheat [5]
The materials were crossed at Sinana Agricultural Research Center; i.e. emmer wheat with durum wheat F1 emmer wheat generation was again backcrossed with emmer wheat two times
Summary
Emmer (Triticum dicoccum) is amember of the wheat family of annual grasses. Wild emmer wheat (T. turgidum spp. dicoccoides (Körn.) Thell.), an annual predominantly selfpollinated [1] tetraploid (genome constitution AABB) species [2], is considered to be the progenitor of cultivated durum and bread wheat’s [3]. Wild emmer is fully compatible with the tetraploid (AABB) durum wheat, it can be crossed with the hexaploid (AABBDD) bread wheat [4], and it harbours wide genetic diversity relevant to the improvement of various economically important traits in cultivated wheat [5]. Dicoccon (Schrank) Thell.], is a tetraploid species (BA-genomes) belonging to the Triticum L.genus [6]. It is predominantly awned with spikelet’s consisting of two well developed kernels. Today the increase in interest in natural and organic products has led to a American Journal of Life Sciences 2017; 5(5): 145-149
