摘要
甜菜多倍体新品种呼育302为多倍体多粒型杂交种,其母本为四倍体双丰1号,父本为二倍体内三71-1.呼育302品种属于标准型(N)品种,有较强的杂种优势,抗病性(褐斑病、黄化毒病)较强,适应性广。在1987~1988年内蒙古自治区甜菜品种区域试验中,其平均块根产量、含糖率和产糖量比对照品种工农4号(CK)提高11.0%、0.3度和13.9%,在1990年的生产示范中,其块根产量、含糖率和产糖量比对照品种提高18.2%、0.9度和28.7%。
The breeding of new sugarbeet polyploid Huyu 302 is described It is polyploid multigermhybrid and it was developed by crossing with tetraploid multigerm CV. Shuangfeng-1anddiploid multigerm line Nteisan 71-1 This CV is N-type, with stroger heterosis, betterresistant to leafspot, beet yellows and have widely adaptabality. The root yield, sugar contentand sugar yield were higher than CK Gongnong-4, with 13.0%,0.3% and 11.9% In InnerMongolia sugar beet variety regional test during 1987~1988. And better than CK with 18.2%,0.9% and 28.7% i n the sugar beet demonstration in 1990.
