“…Thomas (1995) identified a total of 16 local and improved sorghum varieties possessing resistance to foliar anthracnose disease in Mali. Marley et al (2001a) and Marley et al (2001b) reported unique sorghum genotypes of different maturity group (medium to late) showing resistance to foliar anthracnose. Thakur et al, (2007) identified some sorghum lines such as IS 6928, IS 18758, and IS 12467 as the most resistant to anthracnose through testing at various hotspot areas in India, Thailand, Ethiopia, Kenya, Zambia, Nigeria and Mali.…”

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.

“…Due to the economic importance of sorghum anthracnose, various national and international breeding programs are actively involved on prebreeding and breeding of sorghum for anthracnose resistance (Belum, Ramesh, Borikar, & Hussain, ). However, some of the popular released varieties such as KSV 4 (BES) and IRAT 204 and elite lines such as IRAT 204 and 90 SN 7 are still susceptible to the disease (Marley et al, ; Marley, Elemo, Aba, Onu, & Akintayo, ). There is a continuous need to identify new sources of resistance among available genetic stocks and landraces through artificial and natural inoculation for resistance breeding.…”

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.
