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。
The new sugar beet polyculture sweet research 304 is composed of three lines of tetraploid sweet line 426 and diploid sweet line 217, which is a standard polyploid hybrid. Experiments and production demonstration results showed that the sweet root 304 average root yield 1680kg / mu and the sugar content 16.8%. On average, it increased yield by 10% and increased the sugar content by 0.5%. The varieties of leafy plexus growth, good stability, resistance to brown spot disease (the incidence of 0.4 to 0.6 lower than the control varieties), resistance to root rot disease in the incidence of severe block and the year the prevalence of 25% lower than the control, waterlogging Under severe conditions can also be a better yield.
