“…Symptoms of foliar anthracnose infection appear as circular, elliptical, or elongated lesions with acervuli (asexual fruiting bodies) formation in the center of the lesions. Grain yield losses ranging from 30 to 67% have been reported (Ali et al, 1987;Thomas et al, 1996). In Puerto Rico, plant death has been observed before maturing in highly susceptible germplasm accessions (Erpelding and Wang, 2007).…”

“…In Puerto Rico, plant death has been observed before maturing in highly susceptible germplasm accessions (Erpelding and Wang, 2007). Grain yield losses are typically associated with a reduction in grain weight due to poor grain development (Ali et al, 1987). The use of resistant varieties is the most practical method of managing the disease.…”

The United States National Plant Germplasm System maintains 151 sorghum accessions from Burundi of which 148 accessions were evaluated for resistance to Colletotrichum sublineolum at the Tropical Agriculture Research Station in Isabela, Puerto Rico in replicated evaluations during the 2007 and 2008 growing seasons. For the 2007 experiment, 120 accessions showed a resistant response with 89 of these accessions rated as resistant in 2008. The resistant accessions showed reddening of inoculated leaves with no acervuli development, whereas accessions rated as susceptible showed acervuli development on inoculated leaves. Mean infection severity based on the percentage of infected leaf area for the susceptible accessions was 2% in 2007 and 2.5% for the 2008 experiment. Only four accessions showed an infection severity more than 10% and eight accessions showed a susceptible response across replications and growing seasons. Results of this study indicate that sorghum germplasm from Burundi is an important source of anthracnose resistance for sorghum improvement and that germplasm from regions of high annual rainfall is frequently associated with anthracnose resistance.

“…Disease lesions can be circular, elliptical, or elongated in shape depending on host-plant response and acervuli (asexual fruiting bodies) develop in the centre of the lesions of susceptible varieties. Disease development before anthesis can have the greatest effect on grain yield with reported losses ranging from 30% to 67% (Ali et al 1987;Thomas et al 1996). Grain yield losses from foliar disease are commonly associated with a reduction in seed size (Ali et al 1987).…”

“…The most common and severe form of the disease is foliar anthracnose, which can reduce the grain and stover yield of susceptible cultivars by 50% or more (3,11,12). Foliar anthracnose infection causes significant reduction in grain yield through reduced kernel weight and grain abortion (26).…”

Pattern Analysis of Sorghum Genotype × Environment Interaction for Leaf, Panicle, and Grain Anthracnose in Mali

2002

Resistance to anthracnose, caused by Colletotrichum graminicola, in sorghum was identified through field screening at two locations (Samanko and Longorola) in Mali. The occurrence and progress of anthracnose were monitored on 19 sorghum lines plus resistant and susceptible checks in the 1996 to 1998 rainy seasons. Foliar anthracnose severity was assessed at regular intervals throughout the season. Area under the disease progress curve (AUDPC) was calculated for each genotype. Anthracnose severity was also evaluated on the peduncle, rachis and glumes, panicle, and grain. For the characters under study, the site × year and site × year × line interactions accounted for the genotype × environment interactions. Pattern analysis was applied to the environment-standardized matrix of genotype × environment means to analyze these interactions and elucidate genotypic adaptation. None of the lines was completely (hypersensitive) resistant to the disease, but 12 showed high levels of stable resistance to both foliar and panicle anthracnose. Only one was moderately susceptible to both forms of the disease. In addition to identifying varieties that can be grown in zones to which they are adapted, additional genotypes were identified that can serve as sources of resistance in regional breeding programs.
