“…The nursery (a set of sorghum lines, which are tested at different sites against the local fungal population) consists of a local resistant and a local susceptible check and 15-18 sorghum lines, with diverse geographic origins and differential reactions to know pathogen populations identified in earlier nurseries. Until 1998 the ISAVN was evaluated at 9-19 locations in 12 countries in Asia, Latin America, and southeastern, western and central Africa (Mathur et al, 2002). Anthracnose severity was scored at the soft dought stage, on a standard disease rating scale of 1-9, based on percent leaf area covered with necrotic lesions (Thakur, 1995).…”

“…The reduction in 1000-seed mass and seed density, and early abortion of seeds are the most important factors in yield reduction. The premature drying of leaves and defoliation due to foliar anthracnose can reduce the yield of sorghum grain and fodder by 30-50%, or more, in susceptible cultivars during severe epidemics (Mathur et al, 2002). In Burkina Faso, secondary infection of the stalk by red rot phase may cause yield losses proportional to the severity of leaf anthracnose and stalk rot (Neya and Kabore, 1987).…”

ABSTRACT. Anthracnose caused by Colletotrichum graminicola remains the most important foliar disease of sorghum in West and Central Africa. This paper describes the advances made in sorghum anthracnose research that has led to a better understanding of pathogenic and genotypic diversity, epidemiology and important disease management strategies. We further highlight how understanding pathogen diversity interplays with the major sustainable anthracnose management strategies such as the use of host plant resistance and crop residue management within the region.

Sorghum is one of the main staple food crops for millions of subsistence farmers in Africa. Biotic and abiotic challenges are the major production constraints of the crop. Amongst the sorghum biotic constraints, anthracnose is the major devastating disease causing up to 80% of yield reduction. The productivity and profitability of sorghum is limited by several biotic constraints, most notably anthracnose caused by the aggressive fungal pathogen Colletotrichum sublineolum. The most effective and environmentally responsible strategy to control anthracnose is through the incorporation of resistance genes. However, although several sources have been identified, the lack of information with regard to its genetic control of resistance has limited their adequate use in breeding programs. Additionally, the limitations of breeding regarding the leaf and stalk anthracnose resistance and also the need for evaluating materials for resistance and yield in different environments is of major importance. There is limited information about the combining ability, gene action and genetic effects and relationships between anthracnose resistance and grain yield which is required in devising appropriate strategies for developing resistant and high yielding sorghum varieties. This review provides theoretical basis of the progress and challenges for breeding sorghum for anthracnose resistance and improved yield.

Performance of novel sorghum germplasm in Pennsylvania and their response to anthracnose

Sorghum (Sorghum bicolor L.) has the potential to become a widespread commercial feedstock crop in Pennsylvania, either in rotation with maize (Zea mays L.) or grown alongside it. In other locations where sorghum has been grown for a long time, it is attacked by Colletotrichum sublineola Henn. ex Sacc. & Trotter, a fungal pathogen that causes anthracnose (Colletotrichum sublineola) leaf blight (ALB), thereby diminishing yield. Field surveys were carried out in 2011, 2012, and 2016 to monitor the presence of C. sublineola in commercial sorghum fields in six Pennsylvania locations. Senescing, lower leaves developed lesions that yielded Colletotrichum sp., including isolates of C. sublineola. The pathogen was not recovered from field debris, and ALB symptoms were not observed on the younger leaves of plants. In preparation for widespread cultivation of sorghum in Pennsylvania, we evaluated the performance, in field and greenhouse tests, of 158 experimental lines and commercial hybrids, which had been improved in several states in the United States and in other parts of the world. Sources of resistance to ALB and other foliar diseases were discovered that should be useful in breeding programs targeted for Pennsylvania and for northeastern U.S. climatic conditions. Lines received from ICRISAT, especially ICSB94, showed the highest level of resistance in the field.
