河北省主推小麦品种对麦红吸浆虫的抗性鉴定及评价

以河北省目前生产上推广种植的２５个小麦品种对麦红吸浆虫的抗性进行了２年重复鉴定，明确了品种的抗虫性，经方差分析，品种间的产量估计损失率差异达极显著水平（Ｆ＝１７．３５，Ｆ＿０．０１＝２．２２）；品种抗虫性与亲本材料有关，抗虫品种的抗性遗传相对稳定；麦红吸浆虫成虫产卵对不同抗性小麦品种具有一定的选择性，抗虫品种不仅抗产卵，且具有抗麦红吸浆虫侵入的能力。

Identification and Evaluation on Resistance to Sitodiplosis Mosellance Gehin of Wheat Varieties Extended in Hebei Province

Planting pest-resistant varieties of wheat is the most economic and effective measure in controlling Sitodiplosis mosellance. Resistances to Sitodiplosis mosellance of 25 wheat varieties extended in Hebei were known by two years repeating identifications. Differences of estimated yield damage rates between varieties were extremely significant(F=17. 35, Fo = 2. 22). Pest resistances of varieties were relative to parent materials. Resistance inheritance of pest-resistant varieties was relatively stable. Oviposition of Sitodiplosis mosellance had a certain selection to wheat varieties with different resistances. The resistant varieties were not only resistant to oviposition,but,also resistant to invasion of Sitodiplosis mosellance.
