赤霉病是由禾谷镰刀菌引起的玉米赤霉病，是温带玉米上的一种破坏性病害，造成玉米减产和玉米赤霉烯醇类毒素(DON)和玉米赤霉烯酮(ZON)的污染。我们想分析通过GER严重程度分级或近红外光谱(NIRS)预测DON和ZON浓度是否可行。我们分析了在德国和法国的三个地点，从分离群体回交到抗性亲本和感病亲本的回交双单倍体品系的80个和102个品系。这两个回交(BC)群体在所有性状的平均值上都有很大的差异，具有显著的(P<0.01)基因型差异。免疫试验测得的DON和ZON浓度彼此显著相关(P<0.01)，并与每个BC人群中的GER严重程度显著相关(0.6≤r≤(0.9)，P<0.01)。免疫试验测得的DON浓度与近红外光谱呈显著正相关(r≈=0.9P<0.01)。总而言之，GER的严重程度可以可靠地预测DON和ZON浓度。对DON浓度的额外近红外光谱分析可能对肯定选择的组分有用。
Gibberella ear rot (GER) caused byFusarium graminearumis a destructive disease in maize of temperate regions resulting in yield reduction and contamination by the mycotoxins deoxynivalenol (DON) and zearalenone (ZON). We wanted to analyse whether prediction of DON and ZON concentrations is feasible either by GER severity ratings or by near‐infrared spectroscopy (NIRS). We analysed 80 and 102 lines developed by backcrossing doubled‐haploid lines from segregating populations to the resistant and susceptible parent, respectively, by artificial infection at three locations in Germany and France. Both backcross (BC) populations differed substantially in their means for all traits with significant (P < 0.01) genotypic variances. DON and ZON concentrations measured by immunotests were significantly (P < 0.01) correlated with each other and with GER severity within each BC population (0.6 ≤r≤ 0.9, P < 0.01). DON concentration measured by immunotest and NIRS significantly correlated (r≈ 0.9, P < 0.01). In conclusion, DON and ZON concentrations could be reliably predicted by GER severity. Additional NIRS analysis of DON concentration might be useful for the positively selected fraction.
