【摘要】 介绍了甜菜雄性不育多倍体杂交种中甜—工农 30 5的选育过程。中甜—工农 30 5是以二倍体雄性不育系M2 1 2A为母本 ,从品系 334- 1群体中选育出的高糖、抗病四倍体品系TY451为父本杂交而成。该品种在内蒙古河套地区甜菜品种两年区域试验和一年生产试验中平均根产量、含糖率、产糖量分别为51 2 55kg/hm2 、1 5 86%、81 2 9kg/hm2 ,分别比对照提高 1 1 2 %、1 38度和 2 1 7%。中甜—工农 30 5适应性较强 ,较耐褐斑病 ,不耐丛根病 ,适宜在内蒙古河套地区种植 ,适宜密度 82 50 0株 /hm2

【Abstract】 The hybrid variety of sugarbeet MS and polyploid Zhongtian-Gongnong 305 is made by female parent of male sterile line M212A and male parent of tetraploid line TY451 and the rate of triploid came up to 70%.Sterile rate of female parent is stabilized at more than 90% after continued backcrossin of 3 generations.The male parent has a stable expression on yield and quality after the selection of multiple generations.The regional test in autonomous region for two years and one year productive demonstration in large area shown that;root yield 51 255kg/hm\+2,sugar content 15.86°S and sugar yield 8 129kg/hm\+2.Increased by 11.2%,1.38°S and 21.7% to CK respectively.Suitable density 82 500 plants/hm\+2 in west of Inner Mongolia and northwest of China.
