“…The consistency of results among these studies was intermediate between the MSV and GLS studies. In addition to the differences in experimental design inherent to all QTL experiments, this may have been due to the fact that both qualitative (major gene) and quantitative (polygene) modes of resistance to E. turcicum have been identified (Raymundo and Hooker, 1982). Freymark et al, (1993) utilized Mo17, an inbred with moderate levels of partial resistance, and B52, a highly susceptible inbred, in their mapping study.…”

Maize (Zea mays) production in sub-Saharan Africa is constantly threatened by the potential outbreak of multiple foliar diseases such as maize streak, northern leaf blight, gray leaf spot, and rust. Improvement of host resistance to these diseases can provide an important component of integrated pest management (IPM). In this paper, conventional and molecular marker-assisted breeding approaches are reviewed and strategies for improvement of host resistance are presented. Pyramiding of quantitative resistance factors using molecular breeding techniques will be facilitated through cooperative research efforts and adoption of appropriate experimental designs.Key Words: Cercospora zeae-maydis, Exserohilum turcicum, gene pyramiding, molecular breeding, resistance breeding, Setosphaeria turcica RÉSUMÉLa production du maïs (Zea mays) en Afrique au sud du sahara est constamment menacée par l'apparution de multiple infections des feuilles par le streak, le mildiou, le brunissement des feuilles et moisissures. L'augmentation de la résistance a cette maladie peut apporter une importante composante de gestion intégrée de la peste (IPM). Dans cet article, l'approche de croisement assiste des marqueurs conventionels et moléculaires sont présentés et les stratégies d'amélioration de la résistance de la plante hote sont présentées. Les facteurs de résistances pyramidiques et quantitatives utilisant la technique de croisement moléculaires seront facilités à travers les efforts de recherches coopératives et l'adoption d'une approache expérimentale appropriée.

“…Five genes controlling monogenic resistance (Ht1, Ht2, Ht3, HtM and Ht ) have been identified (Gevers, 1975;Hooker 1961Hooker , 1963aHooker , 1963bRobbins & Warren, 1993). Monogenic resistance is associated with the formation of chlorotic lesions, a delay in appearance of necrosis and a marked reduction in sporulation (Raymundo & Hooker, 1982). In the case of Ht , lesion formation is delayed until after flowering (Gevers, 1975).…”

“…Although many corn genotypes have been released from breeding programs, their reactions to NCLB pathogen in North Korea remain largely unknown. Several authors have suggested that the combination of resistance conferred by Ht genes and general resistance would enhance the level of resistance and result in greater stability and longer protection against E. turcicum (Hooker 1977;Hooker and Kim 1973;Kim et al, 2012;Pratt et al, 1993;Raymundo and Hooker 1982). However, this accumulation needs extra efforts in breeding.…”

Exserohilum turcicum is considered serious destructive disease of maize (Zea mays L.) in North Korea. This study aimed to understand genetic inheritance and combining ability of newly bred lines of maize tolerant to E. turcicum by diallel crosses. Three diallel sets for two different ecological regions and one agronomic trait; eastern (E), northern (N) and stay green (SG) involving 29 inbred lines were tested in eight locations of 2000 and 2001. E. turcicum infections were under natural conditions, respectively. Lines used were selected for high yield potential in test crosses with good agronomic traits and tolerance to biotic and abiotic stresses. Selection for race specific high resistance to biotic stresses was avoided to select quantitatively inherited genes. Host plant responses to E. turcicum were rated on a scale of 1 (highly tolerant) to 9 (highly susceptible). Highly significant variations were recorded in all trials. General combining ability (GCA) mean square was roughly twice that of specific combining ability (SCA). The genotype (G) by environment (E) interaction was highly significant. The overall results of genetic studies in three diallel sets show that genetic control for inbred tolerance to E. turcicum is polygenic and quantitatively inherited. New inbreds; E-3, N-1 and SG-4 confer better tolerance to E. turcicum than the widely used inbreds; Mo17, and B73. Proper use of genetic information from this study shall increase of corn production under high E. turcicum infection in the Far Eastern Regions of Korea and China.
