摘要
甜研208(原代号DH084)是以多胚二倍体品系DP23为母本,多胚二倍体品系DP24为父本,父母本按1∶2比例栽植配制而成。该品种于2010—2012年参加黑龙江省甜菜品种区域试验和生产试验,平均根产量分别为52966.0kg/hm2和55041.2kg/hm2,分别比4个对照品种平均值增产0.6%和8.0%,平均含糖率为17.5%和17.1%,分别比4个对照品种平均值提高1.1度和0.9度,平均产糖量为9300.4kg/hm2和9402.3kg/hm2,分别比4个对照品种平均值提高7.2%和14.0%。该品种表现抗褐斑病,耐丛根病和根腐病。主要适宜在黑龙江的牡丹江、齐齐哈尔、哈尔滨、佳木斯等甜菜产区种植。
Tianyan 208 as new sugarbeet variety （original code： DH084） was crossed from a polyembryony diploid line DP23 as the female parent and a polyembryony diploid lines DP24 as the male parent through natural pollination as 2：1. In both Heilongjiang sugarbeet variety regional experiment and demonstration experiment during the years of 2010 to 2012, the mean root yield was 52966.0 kg/ha and 55041.2 kg/ha, increased by 0.6% and 8.0%, the sugar content was 17.5% and 17.1%, increased by 1.1°S and 0.9°S, the sugar yield was 9300.4 kg/ha and 9402.3 kg/ha, increased by 7.2% and 14.0% in comparison with the mean values of four control varieties, respectively. The new variety has shown a good resistance to leafspot and tolerance to rhizomania and root rot. It was suitable to plant in the areas of Mudanjiang, Qiqihaer, Harbin and Jiamusi of the Heilongjiang province.
