“…Several other SSR markers have been reported to be linked to other biotic stresses. For example, Fusarium resistance (Pottorff et al 2012;Omoigui et al 2018), early and late leaf spot in groundnut (Shoba et al 2012;Zongo et al 2017) and Striga resistance in cowpea (Boukar et al 2004).…”

Cercospora leaf spot (CLS) caused by Pseudocercospora cruenta (Sacc.) is an important disease affecting cowpea production in Nigeria. Understanding the genetic nature of CLS is an important step in developing an effective breeding strategy. This study investigated the inheritance of CLS disease in cowpea under natural epiphytotic field condition involving two CLS resistant parents (IT99K-573-1-1, IT99K216-24) and a CLS susceptible parent (UAM09-1055-6). The parental lines, F 1 , BC 1 P 1 , BC 1 P 2 , F 2 and F 3 generations were used to study the genetic nature and to detect SSR markers closely linked with the CLS resistance gene(s) using bulked segregant analysis (BSA). The result showed that F 1 populations involving UAM09-1055-6 9 IT99K-573-1-1 and UAM09-1055-6 9 IT99K-216-24 were resistant to CLS in the 2 crosses suggesting the presence of gene dominance in the control of the disease. The observed segregating ratio of F 2 populations fits the Mendalian ratio 3:1. The plants reaction to the disease in the backcross progeny test involving the resistant parent were all uniformly resistant, whereas those involving the susceptible parent segregated into ratio 1:1. The F 3 generations, which segregated into ratio 1:2:1 further confirmed that resistance was controlled by a single dominant gene in the crosses studied. Heritability estimates varied from 81 to 97%. BSA showed that SSR marker code named RB24 of lima bean and validated on F 2 population discriminated between resistance and susceptibility to CLS. Hence RB24 could be a useful marker for marker-assisted selection in CLS resistance breeding in cowpea.

“…Following screenhouse/ greenhouse studies, four FW resistant cowpea genotypes namely: Asontem, Danila, IT89KD-88 and NE 70 were identified [43,44]. Other genotypes that could be used as resistance donors for FW are: TVu 134, TVu 410, TVu 901-1 and MNCO1-649F-2-1 [45,46]. Genotypes TVu 134, TVu 410 and TVu 901-1 share the same resistance gene [45,46].…”

“…Literature on genetic inheritance of resistance to FW suggests that it is controlled by a single dominant gene [46]. Resistance to race 1, 2 and 3 was reported to be controlled by a single dominant gene [45,56]. Dominant monogenic inheritance makes it possible to effectively use backcrossing for transfer of resistance to susceptible backgrounds [46].…”

“…Little or no progress has been made on markers used or developed for other pathogens. For instance, a single SSR marker (C13-16) that can discriminate between resistant and susceptible genotypes for FW resistance was identified [45]. This marker can easily be used in low resourced laboratories in several developing countries [45].…”

Cowpea [Vigna unguiculata L. (Walp.)], is an important legume crop widely grown in the tropics. Biotic and abiotic stresses cause significant yield reduction in cowpea. In this chapter, we provide a synthesis of information on the damage/economic importance of soilborne diseases of cowpea and present options that can be used to manage these diseases. The aim is to demonstrate that a wide array of control options are available for potential use within an integrated disease management (IDM) framework. Reviewed literature indicated presence of several sources of resistance to fusarium wilt (FW) and charcoal rot but few sources for stem rots, collar rot and damping-off. Major resistant genes and quantitative trait loci (QTL) were identified for FW and charcoal rot and these may be exploited in marker assisted selection (MAS). Cultural practices such as crop rotation and compositing were found to be effective against soilborne diseases, however, there is lack of knowledge regarding their adoption. Similarly, several botanicals were found to be effective against several soilborne fungal diseases but these studies were limited to controlled environments necessitating the need for large scale field trials. Several effective microbial control agents (MBCAs) and fungicides exist and can be incorporated in IDM.
