【摘要】 中甜—吉洮单 30 2为单粒雄性不育杂交种 ,较丰产、高糖、高抗甜菜褐斑病 ,耐甜菜根腐病和丛根病。在 1 996～ 1 998年的轻工国家区域试验 ( 1 0个试验点 )中 ,有 6个点达到高糖型单粒甜菜国家选育标准 ,且含糖率均达到极显著水平。各达标点年度平均 ,与统一对照种HYB - 1 3比 ,根产量提高 3 87% ,含糖率提高 2 0 6度 ,产糖量提高 1 9 2 4 %。生产试验各点平均 ,与HYB - 1 3比 ,根产量提高 1 2 5 4 % ,含糖率提高 1 99度 ,产糖量提高 2 8 80 % ,褐斑病发病级数降低 1 1级 ,根腐病率降低 1 4 76个百分点更多还原

【Abstract】 ZhongTian-JiTao mono302 is sugar beet monogerm MS hybrid.It’s characteristics of higher root yield,high sugar content,high resistance to Cercospora leaf spot,medium resistance to root rot and Rhizomamia.Its avarage root yield,sugar content and sugar yield were over HYB-13(CK) by 3.87%,2.06°S and 19.24% resp.in national sugar beet regional trial from 1996 to 1998;And its above-mentioned three items were over CK by 12.54%,1.99°S,28 8% resp in national sugar beet production demonstration in 1999.Besides,its Cercospra grades were lower than CK by 1.1 scales and root rot rate was 1.02% but CK was 15.78% in above production demonstration.更多还原
