ABSTRACT A seed system can be defined as all activities related to seed production, seed storage, seed management, seed dissemination and seed use. The aim of the study was to evaluate commercial maize cultivars for their resistance to aflatoxigenic fungi under storage conditions in Ethiopia. The collected samples were analyzed using two-way analysis of variance (ANOVA, SAS version: 9.4) and the mean differences were separated by t test (LSD). There was significantly different (p<0.05) of storage fungi incidence on the commercial maize cultivars and the highest incidence 30.00 and 30.33% of A. flavus and A. niger was recorded in BH661 and BH546, respectively. There were significantly different (p<0.05) variations of germination percentage of the maize cultivars over the locations. The highest germination 97.33% was obtained from Jibat cultivar whereas the lowest 72.67%% was recorded in BH546. In all the five commercial maize cultivars analyzed, aflatoxin types were not detected and quantified because it was below the quantification limits of 0.35μg/kg and the development of secondary metabolite was low due to less development of the factors that aggravated it in the seed’s storage. This study showed storage periods have low effect on the development of mycotoxins/secondary metabolite on the seeds of commercial maize cultivars since the taken samples were stored for more than one to three years but no aflatoxins types were detected. Therefore, from this study it was concluded that seed storage has less impact for the aflatoxin types development but has a high impact on the seed germinations. |
