优质食用型向日葵杂交种A9选育报告:食用型向日葵A9是甘肃省农业科学院经济作物与啤酒原料研究所与甘肃金大农业科技合作选育的胞质互作型雄性不育三系杂交种,其杂交组合是G06A×8198R。该品种农艺性状优良,抗倒伏,较抗菌核病、黄萎病和白粉病。在2023—2023年甘肃省食用型向日葵多点区域试验中,平均折合产量4111.5kg/hm2,较对照品种LD5009增产6.3%。在2023年甘肃省食用型向日葵生产试验中,A9平均折合产量4272.0kg/hm2,比对照品种LD5009增产6.7%。该品种品质优良,粗脂肪含量为24.2%(干基),粗蛋白含量为19.7%(干基)。适宜在甘肃省沿黄灌区、河西、天水及新疆、内蒙古、宁夏向日葵种植区推广种植,或在低海拔光照充足地区麦后复种。关键词:食用型向日葵;杂交种A9;选育中图分类号:S565.5文献标志码:A文章编号:1001-1463(2023)07-0006-03doi:10.3969/j.issn.1001-1463.2023.07.003Abstract:A9isanewlythreelinematchingediblesunflowercultivarbyparentalwhich8193Rasmaleparent,G06AasfemaleparentbyInstituteofEconomicCropsandBeerMaterial,GansuAcademyofAgriculturalSciencesandGansu,JindaSeedIndustryCo.,Ltd..Theagronomiccharactersofcultivarsareexcellent,lodgingresistance,nucleardiseaseresistance,verticilliumwiltresistanceandpowderymildewresistancearestrong.In2023—2023,theaverageyieldofA9is4111.5kg/hm2whichisincreasedby6.3%,comparedwiththecontrolLD5009inmulti-areaexperimentofGansu.TheaverageyieldofA9is4272.0kg/hm2whichisincreasedby6.7%,comparedwiththecontrolLD5009inproductiontestingofGansu.A9aregoodquality,crudefatcontentis24.2%(drybasis),proteincontentis19.7%(drybasis).A9ismaintainedbyGansuCropCultivarApprovalCommitteein2023.ItissuitabletoplantinirrigationareaalongtheYellowRiver,theHexi,TianshuiandXinjiang,InnerMongoliaandNingxiasunflowergrowingareas,ormultiple-croppingwheataftertheharvestinthelowaltitude,adequateilluminationareasinGansu.Keywords:EdibleSunflower;HybridA9;Breeding食用型向日葵是甘肃省的主要经济作物之一,其生育期短,适应性较强,耐瘠抗旱,可单一种植,或与其他作物间、套、混种,因此具有较高的经济效益。但由于近年来水资源日益紧张,十年九旱,导致食用型向日葵受到不同程度的水分胁迫[1-6],加...
