抗赤霉病小麦新品种轮选22的选育及性状表现

目的]探讨抗赤霉病小麦(Triticum aestivum Linn.)新品种轮选22的推广价值及应用潜力.方法]介绍轮选22的选育经过,并分析其主要特征特性、产量表现、品质、适应范围和利用前景,最后概述了其栽培要点.结果]轮选22(原代号皖0202,皖麦202)系安徽省农业科学院作物研究所利用矮败小麦进行轮回选择选育而成的抗赤霉病小麦新品种.该品种弱春性,一般单产6.0 ～9.0 t/hm2,适于沿淮及淮南地区中上等肥力水平的地块种植；株高80～85 cm,长芒、白壳、白粒、丰角质,千粒重40 g左右,后期转色好,不早衰,特别是对小麦赤霉病抗性强,作为稻茬麦优势更强.适宜播种期为10月中下旬至11月初,基本苗可掌握在180万～270万/hm2.结论]轮选22性状优,产量高,品质好,在沿淮及淮南地区具有广阔的应用前景.

Breeding and Characteristics Performance of Lunxuan22,A New Variety of Wheat(Triticum aestivum Linn. ) with High Resistance to Fusarium Head Blight

Objective] The aim was to discuss the popularization value and application potentiality of Lunxuan 22,a new variety of wheat with high resistance to Fusarium head blight(FHB).Method] The breeding process of Lunxuan 22 was introduced,and its main characteristics,yield performance,quality,adaptation range and utilization prospect were analyzed,and finally its cultivation pints were summed up.Result] Lunxuan 22 was bred by Recurrent Selection with Dwarfing Sterile Wheat in Crops Research Institute of Anhui Academy of Agricultural Sciences.It showed some spring habit with high yield range from 6 to 9 t/hm2,high resistance to FHB and best adapt to the reaches of the Huaihe River and the Yangtze River.Lunxuan 22 had strong resistance to FHB and had stronger dominant as wheat after rice with no premature senility,long awn,white shell and grain,half part of cutin,turning into color good in later stage,and its plant height was 80-85 cm,1000-grain weight was 40 g.Its suitable sowing time was from the second and third ten days of October to the first ten days of November,and the basic seedlings kept in 180×104-270×104 per ha.Conclusion] Lunxuan 22 has characteristics of outstanding traits,high yield,good quality,and has wide application prospect in the Huaihe River and the Yangtze River.
