Results suggest that inbred maize lines resistant to the race 0 and
susceptible to the race 1 (Fig. 1d, e) carry the Ht1 gene, while inbreds resistant to
both races probably carry genes different from the Ht1 gene.
These findings suggest that more studies on the racial specialisation in
Serbia are needed and that in regard to the NLB management, it is necessary to
incorporate other Ht genes besides Ht1, which has been intensively used since the
1980s. Resistant genotypes described in this study could be used as sources of
resistance in the breeding programme, especially genotypes genetically different
from Ht1, but resistant to both E. turcicum races, 0 and 1. Open-pollinated varieties
(Yugoslav and Argentinean) are particularly interesting as a source of resistance to
these races. As early as the 1980s, LEVIC at al. (1983) and PENCIC and LEVIC
(1981), working with local varieties, observed that the Yugoslav varieties were a
good source of monogenic resistance to E. turcicum, especially from the group of
dent types of the USA Corn Belt dents that were most often used for deriving
maize inbreds and ZP hybrids.
