| Summary: | The disease progress rate and the level of resistance to brown spot was evaluated in barley cultivars.The field experiment was carried out at Embrapa Trigo Experimental Station in Coxilha, Rio Grande do Sul, Brazil. Cultivars BR 2, MN 698, Embrapa 128, Embrapa 129, and CI 9539 showed statistical differences from one another regarding reaction to and severity of seed infection by brown spot, based on the scales of Fetch & Steffeson (1999) and Anderson & Banttari (1976), respectively. Cultivars BR 2, Embrapa 128, Embrapa 129, andMN 698 showed the greatest increase in the rate of the disease progress, which varied from 2.92 to 3.62 compared to access CI 9539, even though there was no statistical difference (P > 0.05) among those cultivars. Access CI 9539 showed the lowest rate of disease progress (1.17). |
