Abstract

Sorghum is an important food security crop in Ethiopia and major food crop in Tigray region. However, the yield of the crop is low owing to several factors among which are drought, striga, limited improved varieties, low adoption rate and intensity and inappropriate agronomic management. Therefore, a field experiment was conducted to evaluate and select best high yielder and early maturing sorghum genotype/s during the main cropping season of 2017 and 2018 at Sheraro, Rama and Maiayni locations (North Western and Central Tigray), Ethiopia. Fourteen  sorghum  genotypes including one standard and one local checks  were  sown  in  Randomized  Complete  Block design  (RCBD)  with  three replications. The combined  analysis  of  variance  showed significance difference due to  the main effect of Genotype (G), environment (E), Year (Y) and interaction  effect of G X E at (p<0.05) for grain yield and other studied traits. The genotype G24 (WSV387/76T1#23)  gave grain yield 3.31  t  ha-1  followed by G86 (3.21 t ha-1) produced  the   highest  grain  yield  than  other genotypes and those genotypes achieved  46.4% & 20.5% yield advantage over the standard and local checks, respectively. While, the lowest grain yield was recorded by G82 (IESV92084/E36-1) (1.55 t ha-1). But based on ASV and Genotype stability index  (GSI)  genotypes G86 revealed the highest  yield stability index and mean grain yield with  over all phenotypic acceptability (regard to yield, earliness, seed color &size and uniformity ) advanced to variety verification trial to be evaluated by NVRC in 2019/2020 cropping season.
