【摘要】 [目的]了解新育成品种的推广利用价值。[方法]以豫麦49为对照,对河南省2005~2006年度高肥冬水组14个区试小麦新品种的丰产稳产性进行了分析。[结果]郑农17和周99343较对照增产极显著,其穗粒数高4.2粒,千粒重高3.8 g,抗倒、抗病性强,稳产性好,适合在河南省高水肥田推广;郑366较对照增产,产量结构合理,植株较矮,抗倒、抗病性较好,稳产性较好,适合在中高水肥田种植;周麦19较对照增产,稳产性较高,综合抗病性一般,适合在中高水肥田种植;许农5号产量最高,但稳产性较差,适宜在豫西地区推广种植。其他品种均以高产与稳产不协调,不宜推广种植。[结论]郑农17和周99343丰产性和稳产性最好,郑366和周麦19丰产性和稳产性较好。

【Abstract】 [Objective] The research aimed to know about the popularization and utilization value of newly bred varieties.[Method] With Yumai 49 as control variety,the high-yield stability of new wheat varieties of 14 regional tests of winter wheat group with high fertilizer and water in Henan province in the year of 2005-2006 was analyzed.[Result] Zhengnong 17 and Zhou 99343 had extremely significant yield increase than the control variety,with grains per spike grains being higher 4.2 and kernel weight being 3.8 g higher,and the two varieties were in lodging resistance,strong disease resistance and good yield stability,so that they were suitable to be extended in the farmland with high fertilizer and water in Henan.Zheng 366 had yield increase compared with control one,it was in rational yield structure,shorter plants,lodging resistance,stronger disease resistance and better yield stability and fitted to be planted in the farmland with high and medium fertilizer and water.Zhoumai 19 had yield increase than the control one,it was in higher yield stability and general comprehensive disease resistance,and fitted to be planted in the farmland with high and medium fertilizer and water.Xunong 5 was in the highest yield but in worse yield stability,and was suitable to be extensively planted in the western Henan area.The other varieties all were not coordinated in high yield and yield stability,so as not to be planted widely.[Conclusion] Zhengnong 17 and Zhou 99343 had best high yield and yield stability,and Zheng 366 and Zhoumai 19 had better high yield and yield stability.
