“…A number of dominant or partially dominant major genes have been discovered conferring race-specific resistance to NLB, including Ht1 (Hooker et al 1963), Ht2 (Hooker 1977), Ht3 (Hooker 1981), Ht4 (Carson 1995), Htn1 (Gevers 1975), HtP (Ogliari et al 2005), and Bx (Couture et al 1971). The Ht genes render delayed lesion development or chlorotic lesions rather than complete resistance, which suggests that the Ht genes should be considered as large-effect, race-specific QTL (Balint-Kurti and Johal 2008).…”

The significance of N, K and P fertilizers on corn yield and smut incidence was evaluated in the field during the seasons 1988 and 1989. Rates of fertilizers were 30, 60 and 90 kg N/acre; 0, 50 and 100 kg K2O/acre and 0 and 30 kg P2O5/acre. The corn plants were artificially inoculated with U. maydis spore suspension at 6‐leaf growth stage. The results showed that N fertilization acted to enhance N content of ear‐leaf and smut index and imposed depressing effects on leaf K. Unlike N, enhanced K‐fertility performed opposite results on leaf N and smut index. A significant N x K interaction was detected on ear‐leaf K and smut index, due to the antagonistic effects between ions. Grain yield data showed positive response to each N, K and P application, but the effect was much greater at the highest application rates. Yield losses were clearly pronounced, along all of the applied nutrient fertilizers, on plants where galls are located above ear than those with galls below ear. On average, the relative losses were 12.8 and 5.9 %, respectively, compared with 3.7 % for the main plot treatment. The 2‐way interaction (except N × P) showed variable effects on yield performance.
