【摘要】 中甜—吉甜单粒二号(原代号吉DMS92-16)是以单粒二倍体雄性不育系“7587-22A”为母本,以多粒型二倍体抗病品系“SC-205”为父本杂交而成,该品种1996～1998年参加全国甜菜品种区域试验,平均根产量、含糖率、产糖量分别比对照高6.3%、1.37度和16.9%;1998～1999年参加东北区和华北区生产试验,平均根产量比对照提高9.6%,含糖比对照提高1.41度,产糖量比对照提高21.0%。抗褐斑病性强,平均比对照低1.3级,比较耐根腐病。适应华北区、东北区种植。更多还原

【Abstract】 Zhongtian-Jitian MonogermⅡ(code Ji DMS92-16)acrossed from7587-22A(MS monogerm diploid line)as the female parent with SC-205(polygerm diploid with disease resistance)as the male parent .In the national regional sugarbeet variety trial during the years1996to1998,the results showed that the root yield,sugar content and sugar yield of the variety were increased by6.3%,1.37°S and16.9%respectively;in the productive demonstration trial in northeast or north China in1998～1999,its mean root yield,sugar content and sugar yield were also increased by9.6%,1.41°S and21.0%respectively.The variety had strong leaf spot resistance,and disease rate was decreased by1.3in comparison with check test,it was relatively tolerant to root-rot,and is suitable for planting in northeast or north China.更多还原
