tailieunhanh - Spot blotch resistance in derivatives of European winter wheat

The effects of inoculum concentrations and the aggressiveness of spot blotch (Bipolaris sorokiniana (Sacc.) Shoemaker) isolates were evaluated on the resistance of 123 winter wheat advanced breeding lines developed from European winter wheat as well as on 3 control cultivars, BR8, BH1146, and Zentos. | Ž.

Shoemaker) isolates were evaluated on the resistance of 123 winter wheat advanced breeding lines developed from European winter wheat as well as on 3 control cultivars, BR8, BH1146, and Zentos. The test was conducted under laboratory conditions using a detached leaf technique. A total of 3 inoculum concentrations were used: × 103, 1 × 103, and 5 × 103 spores mL–1. The results of the study revealed low resistance of the tested material when accessions were compared by the percentage of disease severity (DS), but considerably higher variability of resistance was determined when the area under the disease progress curve (AUDPC) was used for comparison. The correlations between DS and AUDPC across inoculum concentrations varied from medium to high (r = ***; *P < , **P < ) for isolates with higher aggressiveness, whereas it was high (r = ****) for those with lower aggressiveness. The correlations between DS and AUDPC across isolates were high (r = ****) for lower inoculum concentrations of × 103 and 1 × 103, whereas they varied from medium to high (r = ***) for the highest spore concentration, 5 × 103. All of the concentrations can be successfully used for the evaluation of resistance considering DS development and the subsequent differentiation of accessions. However, the lower inoculum concentrations provided a higher differentiation of the accessions tested. Cultivar BR8, described in the literature as being resistant, exhibited
