在对小麦品种进行多种主要病虫害抗性鉴定中,河南偃师农科所送来的山前×偃师4号的76(64)0—2—11选系,表现对小麦条锈病、赤霉病、黄矮病、黄叶病和吸浆虫都有较好的抗性;且矮秆、早熟和丰产;唯不抗雪霉叶枯病和白粉病,落黄不好,且有继续分离现象。于是我们选叶片好和尖头的单株,继续进行抗病虫鉴定和产量比较试验。从363个单株中选出了多抗2号(白粒),比原选系有明显提高,比该所从中选出的偃师9号(红粒)增产。
In the identification of wheat varieties for major pest and disease resistance, 76 (64) 0-2-11 selected from Panshan × Yanshi No. 4 sent from Yanshi, Henan Province showed resistance to wheat stripe rust, red Mildew, yellow dwarf, yellow leaf and midgelfans have better resistance; and dwarf, early maturity and high yield; only do not resist the snowy mildew and powdery mildew, falling yellow bad, and continue to separate . So we choose the leaves of good and pointed single plant, to continue the identification of pest and yield and yield comparison test. From 363 single plants, we chose Duoyao No.2 (white grain), which is obviously higher than the original selected line, and Yanshi 9 (red grain) is more than the selected ones.
