Abstract: | The effect ofRhizoctonia solani infection on the yield and quality of tubers destined for processing was evaluated in a 10 × 2 factorial experiment. Inoculation of 10 cultivars withR. solani significantly decreased total and marketable yields and significantly increased the number of malformed and fissured tubers as well as the number of tubers with black scurf. Specific gravity was significantly decreased in 3 of the 4 years. Chip color at harvest was adversely affected in 2 of the 4 years and over the 4 years combined; whereas chip color three months after harvest was adversely affected in all 4 years. |
