The basic components of the disease (Exserohilum turcicum [Setosphaeria turcica]) are overall disease damage (score), length, width and area of the lesion, number of lesions, number of flecks and lodging. The overall disease damage (score) is considered to embrace or integrate all the components of the plant response. The damaged leaf area reflects the spread of the disease, while the fleck number reflects the hypersensitive reaction. Consequently, the sorghum genotypes with low fleck number and less leaf area damage were the most desirable. The sorghum hybrids SPLB 94012A, SPLB 94015A and SPLB 94006A crossed with ICSR 119; SPLB 94004A, SPLB 94012A, SPLB 94015A, SPLB 94017A, SPLB 94021A and 296A crossed with ICSR 26; and SPLB 94004A, SPLB 94006A, SPLB 94003A, SPLB 94015A, SPLB 94013A, SPLB 94021A and SPLB 94017A crossed with ICSR 90030 were resistant and stable in disease expression over two years (1996 and 1997).
