【摘要】 中甜—吉甜单粒3号是以本所培育的二倍体单粒雄性不育系7587-22A1为母本,多粒二倍体品系SC-203为父本杂交而成。该品种1999～2001年参加全国甜菜品种区域试验,根产量、含糖率、产糖量分别比CK1(多粒种对照)提高22.3%、低0.17度、提高22.2%;与CK2(单粒种对照)比提高2.8%、1.14度、11.1%。中甜—吉甜单粒3号2002年参加东北区、华北区生产试验,4个点次根产量、含糖率、产糖量与CK1比提高15.5%、低0.05度、提高15.3%,与CK2比提高1.9%、高1.35度、提高11.4%,中甜—吉甜单粒3号属于高产型二倍体单粒雄性不育杂交种。更多还原

【Abstract】 Zhongtian-Jitian monogerm 3 is bred by crossing in which female parent is diploid monogerm MS line 7587-22A1 and male is diploid multigerm line SC-203.In the national regioual test of sugarbeet variety from 1999 to 2001,the variety showed that averase root yield and sugar content and sugar yield increased by (22.3%) and (0.17)°S and (22.2%) than CK1 multigerm check variety,as well as increased (2.8%) and　(1.14)°S and (11.1%) than CK2 (monogerm check variety),respectively.During the productive demonstration of northeast and Huabei region in 2002,the variety’s average root yield and sugar content and sugar yield increased by (15.5%) and 0.05°S and (15.3%) respectively than CK1,as well as increased by (1.9%) and (1.35)°S and (11.4%) respectively than CK2,the variety belongs to high-yielding type diploid monogerm MS crossing variety.更多还原
