This study was conducted to evaluate the effect of seed priming on seed germination of korerima genotypes. Two genotypes were used to assess the effect of priming on seed quality potential in CRD with three replications in factorial arrangement of six priming materials (distilled, tap water, cow urine, gibberellins acid, potassium di-hydrogen phosphate, potassium nitrate) and three priming durations at Tepi National Spices Research Centre in 2016-2017. Analysis of variance results revealed that the presence of significant differences among genotypes for all characters. Unprimed seed of genotypes seed germination percentage and speed of germination ranged from 48.33% to 73.33% and 2.83 to 4.45, respectively. Priming had improved the seed germination potential significantly of the two korerima genotypes (093/00 and 059/03) with varied magnitude in which seed germination and speed of germination of primed seeds improved by about 11.62 to 41.99% and 1.16 to 3.57, respectively. The percentage of normal seedlings increased by about  5.61 to 18.24%, while fresh ungerminated and dead seeds significantly reduced by about  14.33 to 15.87 and 1.75% to 4.59%, respectively, as compared to unprimed seeds. Generally, primed seeds with gibberellins acid and cow urine were significantly improved the seed quality of korerima than other priming materials.

Keywords: korerima, gibberellins, cow urine, priming, seed germination and speed of germination.
