“…The use of resistant cultivars (Casela, Frederiksen, & Ferreira, ; Casela & Frederiksen, ; Moore, Ditmore, & Tebeest, ; Chala et al., ; Costa et al., ) and fungicide application (Costa et al., ; Cota, Costa, Silva, & Lanza, ; Resende, Rodrigues, Costa, & Silva, ) are the primary measures for controlling anthracnose in sorghum. Besides these, mixture of genotypes (Guimarães et al., ; Silva et al., ), rotation of cultivars (Silva et al., ), dynamic multiline population approach (Costa, Zambolim, Silva, Cota, & Casela, ) and pyramids of genes (Casela et al., ) are additional strategies to increase the durability of sorghum resistance to C . sublineolum .…”

Besides these, mixture of genotypes (Guimarães et al, 1998;Silva et al, 2015), rotation of cultivars , dynamic multiline population approach (Costa, Zambolim, Silva, Cota, & Casela, 2012) and pyramids of genes are additional strategies to increase the durability of sorghum resistance to C. sublineolum. In Brazil, a preventive fungicide application is recommended whenever susceptible genotypes are planted and the environmental conditions are favourable to the development of the disease (Costa et al, 2009;Cota et al, 2011;Resende et al, 2013).…”

“…Sorghum is a versatile crop, used as human and animal food, feedstock for energy production, fodder and production of starch and starch derivatives (Taylor, Schober, & Bean, 2006;Proietti, Nasini, Reale, Ferranti, & Caruso, 2015;Xin et al, 2016). In Brazil, sorghum is widely cultivated in different climates and all parts of the plant are used for animal feed production (Tabosa, França, & Santos, 1993;Dykes, Rooney, Waniska, & Rooney, 2005;Rooney, 2007;Silva et al, 2015). Recently, in Brazil, the area cultivated with sweet sorghum has experienced a significant expansion due to the high demand for ethanol production (Barcelos, Maeda, Betancur, & Pereira, 2011).…”

The leaf anthracnose disease in sorghum, caused by Colletotrichum sublineolum (Henn. ex Sacc. & Trotter), is widely distributed throughout its Brazilian cultivation areas. The disease can cause significant losses in grain yield and quality. This study aimed to quantify the effects of leaf anthracnose on grain yield of different sorghum genotypes. Two elite inbred lines of sorghum, BR009 (susceptible) and BR008 (moderately resistant), and the hybrids, BR304 and MR43 (susceptible), BRS310 and DKB599 (moderately resistant) and BRS308 and AG1060 (resistant), were planted in a complete randomized block design with three replicates. The disease severity (DS) was evaluated weekly, starting from the onset of the first foliar symptoms, and yield losses were estimated using linear regression analysis. Leaf anthracnose significantly reduced sorghum yields in the susceptible genotypes. The highest yield loss of 86% was observed in the inbred line BR009, when the disease severity reached 100%. For the hybrids, the grain yield loss varied from 35% (BRS310) to 72% (BRS308). According to the adjusted model, a grain yield reduction of 23.48 kg/ha for BR304, 14.57 kg/ha for BRS310 and 15.91 kg/ha for DKB599 was observed for every 1% increase in disease severity. We demonstrate for the first time the effect of leaf anthracnose disease on grain sorghum yields under Brazilian conditions. The results from this study provide a starting point for developing new strategies for the integrated disease management of sorghum anthracnose.

“…Anthracnose can be controlled using different options including fungicides, cultural practices such as weed and residue management, planting disease free seeds and crop rotation and host resistance (Mathur 2002;Erpelding and Prom 2004;Chala et al, 2010;Silva et al, 2015). In west and central Africa, proper crop residue management assisted in minimizing anthracnose disease (Marley et al, 2005).…”

Sorghum [Sorghum bicolor (L.) Moench] is an important cereal crop grown for its diverse uses. Global sorghum production and productivity is affected by various stresses notably by biotic factors such as diseases, weeds and insect pests. Anthracnose caused by the fungal pathogen Colletotrichum sublineolum Henn. (formerly known as C. graminicola [Ces.] G.W. Wilson), grain mold, leaf blight, rust and smut are among the most import diseases of sorghum, while stem borer, shoot fly, termites and birds are notable pests of the crop. Sorghum anthracnose occurs in epidemic proportions under high temperature and humidity conditions causing yield losses reaching up to 67% in susceptible varieties. Sorghum shows considerable genetic variation. A large number of landraces are exploited in breeding for disease resistance and better agronomic performance. This review presents literature on breeding sorghum for anthracnose resistance and associated challenges and opportunities. Information presented in this paper may guide future breeding of sorghum varieties incorporating farmer needs and preferences.

“…Various control options are internationally recommended to minimize yield losses. These include use of fungicides, cultural practices, disease free seeds, crop rotation and host resistance (Chala, Alemu, et al, 2010;Erpelding & Prom, 2004;Mathur et al, 2002;Silva et al, 2015). Crop protection chemicals are expensive and crop residue management in crops such as sorghum is difficult to apply.…”

Sorghum anthracnose caused by Colletotrichum sublineolum Henn. is one of the key diseases limiting sorghum production and productivity. Development of anthracnose‐resistant sorghum genotypes possessing yield‐promoting agronomic traits is an important breeding goal in sorghum improvement programs. The objective of this study was to determine the responses of diverse sorghum genetic resources for anthracnose resistance and agronomic traits to identify desirable lines for breeding. A total of 366 sorghum collections and three standard checks were field evaluated during the 2016 and 2017 cropping seasons. Lines were artificially inoculated with a virulent pure isolate of the pathogen. Anthracnose disease severity was assessed to calculate the area under disease progress curve (AUDPC). Agronomic traits such as panicle length (PL), panicle width (PW), head weight (HW) and thousand grain weight (TGW) were measured. Lines showed highly significant differences (p < .001) for anthracnose severity, AUDPC and agronomic traits. Among the collections 32 lines developed levels of disease severity between 15% and 30% in both seasons. The following sorghum landraces were selected: 71708, 210903, 74222, 73955, 74685, 74670, 74656, 74183, 234112, 69412, 226057, 214852, 71420, 71484, 200126, 71557, 75120, 71547, 220014, 228179, 16212, 16173, 16133, 69088, 238388, 16168 and 71570. These landraces had a relatively low anthracnose severity possessing farmer‐preferred agronomic traits. The selected genotypes are useful genetic resources to develop anthracnose‐resistant sorghum cultivars.
