中文摘要：本研究旨在评估一批欧洲冬小麦品种跨环境控制II型FHB抗性的一般配合力和特殊配合力效应,并为将来的品种选育鉴定具有合适的FHB抗性水平的可能亲本组合。结果表明，即使用中等抗性品种与易感品种杂交也可能获得低DON含量的后代；另一种可能性是在杂交小麦中直接利用所需抗性（降低DON含量和减轻症状表现）的杂种优势。
外文摘要：The aims of the present study were to estimate the general combining ability (GCA) and the specific combining ability (SCA) effects controlling type II FHB resistance across environments in a set of European winter wheat varieties and, for purposes of future selection, to identify potential combinations of parents with suitable levels of FHB resistance. Parental varieties as well as F-1 generations were evaluated under both field and greenhouse conditions in two years. The results of the present study indicate that in the F1 generation mean DON content was relatively lowest after crossing of moderately resistant parents (Sakura/Bakfis, Sakura/Federer, Petrus/Bakfis, and Sakura/Petrus), and mean DON content is low also after crossing the moderately resistant Bakfis variety with the susceptible Biscay and Cubus varieties. Evaluation of crosses in the F1 generation was followed by evaluation of selected crosses (derived from the Bakfis and Sakura varieties) in the F-2 generation. Correlations between F1 and F2 were highly significant in relation both to their DON content and visual symptom score (VSS), as well as between the individual experiments (and in the different years). The only exception was in the case of the 2014 field experiment, when inoculation was successful but conditions were not optimal for the disease to progress and DON to accumulate. The selection of a suitable parental variety (with a high GCA) can markedly influence the success rate of breeding for resistance to FHB. Detection of high SCA in the F1 generation is important for directing breeders to promising combinations for achieving FHB resistance. It was demonstrated here that low DON content may be achieved even after crossing a moderately resistant variety with susceptible varieties. Another possibility is to make use of heterosis directly for acquiring resistance in hybrid wheat (for decreasing DON content and manifestation of symptoms).
