| 摘 要： | 甜菜多倍体新品种甜研304由四倍体品系甜426的3个系号与二倍体品系甜217杂交育成,该品种属标准型多粒多倍体杂交种。试验、生产示范结果,甜研304平均块根产量1680kg/亩,含糖率16.8％,平均比对照增产10％,提高含糖0.5度。该品种叶丛长势强、稳产性好,抗褐斑病(发病率较对照品种低0.4～0.6级)、耐根腐病,在发病严重地块及年份罹病率较对照低25％,水涝严重条件下亦可获得较好产量。

| Abstract: | The new sugarbeet polyploid variety of Tianyan 304, acquired by hybridization between three lineages of tetraploid line of Tian 426 and diploid line of Tian 217, is a hybrid strain of standard multigerm and polyploid. The results of experiment and productive demonstration indicated that the average root yield of Tianyan 304 is 1680kg/mu, exceeding the control by 10 percent, and that sugar content is 16.8 percent, increasing by 0.5 percent. The variety with strongly growing power of leaf fascical, stabl yield, resistance to leaf spot (the incidence of the disease is lower than (onto by 0.4-0.6 grade) and root rot tolerance, has a lower incidence of diseases than control in the plot and on the year with serious diseases, and also acquires more yield in the heavily waterlogged field. |
