摘要
郑红22系河南省农业科学院粮食作物研究所与江苏省徐州甘薯研究中心于2001年从徐01-2-9开放授粉杂交后代中选育而成的高产、优质、高淀粉、抗病兼用型甘薯新品种,原品系号为郑04-4-2。2008-2009年参加国家北方薯区甘薯新品种区域试验及生产鉴定试验,平均鲜薯产量分别为30 763.5 kg/hm2、29 313.0 kg/hm2,该品种淀粉含量25.9%,烘干率34.74%,高抗茎线虫病,抗根腐病。2010年3月通过国家甘薯品种鉴定委员会鉴定。
A novel sweetpotato variety,Zhenghong 22,has comprehensive excellent properties in terms of high yield,high quality,high starch content and stem nematode resistance.This variety was selected from open pollination progenies of Xu 01-2-9 with the method of conventional hybridization by Cereal Research Institute of Henan Academy of Agricultural Sciences and Xuzhou Sweetpotato Research Center.Its original line number was Zheng 04-4-2.The yield,characteristics,disease resistance and other properties were determined through new sweetpotato variety regional test in National Northern Sweetpotato Area and National Sweetpotato Production Area from 2008 to 2010.The average yield of fresh root was 30 763.5 kg/ha,and 29 313.0 kg/ha,respectively.Zhenghong 22 had starch content of 25.9% and drying rate of 34.74%,and was high resistant to stem nematode.This variety was identified by the national variety identification committee in March of 2010.
