甜菜新品种甘糖一号选育体会

The Selection on the New Variety GanTang No. 1 of Sugarbeet

甘糖一号多粒型二倍体品种是甘肃省自育的第一个甜菜新品种。该品种采用系统选择法于1980年开始培育,亲本材料为工农二号(引自波兰的K.Bus—p),对西北地区有较好的适应性。甘糖一号属于标准偏高糖型甜菜品种,对黄化毒病有较高的抗性,产量优于对照品种工农二号,1987年生产示范结果的平均值为:根产量3697.8kg/亩、含糖率16.74％、产糖量616.5kg/亩,比对照品种分别增加8.3％、1.06度和16.0％;1988年生产示范结果的平均值为:根产量5267.4kg/亩、含糖率16.52％、产糖量861.2kg/亩,比对照品种分别增加12.6％、1.03度和20.5％。

Using the method of systematic selection the multigerm diploid variety GanTang No. 1 was bred in Gansu province, which was the first new sugar- beet variety developed in the province. The breeding work began in 1980. The parent of GanTang No. 1 is GongNong No. 2 whose parent is K. Bus-p of Poland and the new variety has better adaptability to the natural con- dition in the northwest of China. It belongs to the “NZ”type in sugarb vareties and has stronger resistance to the beet yellow virus. It's root yield and sugar yield were higher than those of check variety GongNong No. 2. The average value of the results of this variety in production demonstration in 1987 and 1988 were as following: root yield 3697.8 Kg/mu (one mu=1/15 hectare), sugar content 16.74％ and sugar yield 916.5 Kg/mu for 1987, having increased over the ck by 8.3%, 6.8％ and 16.0％ respectively; ry 5267.4Kg/mu, sc16.52% and sy861.2 Kg/mu for 1988, having increased over the ck by 12.6%, 6.6% and 20.5% respectively.
