Abstract

The goal of the investigations was to complexly evaluate sugar beet breeding material productivity and technological indices and to select competitive hybrids. The object of the investigations was comparison of simple and trial domestic hybrids of sugar beet with the group standards of the foreign hybrids: Mitika (Lion Seeds) and Dubravka (KWS). The investigations included a field experiment, laboratory analysis of sugar beet using the Betalyser computer-aided line. The analysis comprised 111 domestic hybrids, including 26 simple and 85 trial ones. Based on the complex evaluation of sugar beet breeding material according to productivity and technological quality, four simple and six trial hybrids with high values of sugar content and predicted sugar output were selected, which exceeded or were at level of the group standard in beet root yield and white sugar yield. The trial hybrid nos. 1262 and 1264 are worthy of special attention since they exceed the group standard in sugar content by 0.55 and 0.60% absolute, predicted factory sugar output by 0.48 and 0.63% absolute, beet root yield by 6.89 and 22.77%, and white sugar yield by 10.10 and 27.69%, respectively. The chosen promising sugar beet hybrids are suggested to breeders for further work.

按生产力和技术质量综合评价和选择国产甜菜育种材料

摘要

研究的目的是对甜菜育种材料的生产力和技术指标进行综合评估，并选择具有竞争力的杂种。研究的目的是将甜菜的简单和试验性国内杂交种与国外杂交种的组标准：Mitika（狮子种子）和Dubravka（KWS）进行比较。调查包括现场试验，使用Betalyser计算机辅助线对甜菜进行实验室分析。分析包括111个家庭杂种，包括26个简单杂种和85个试验杂种。根据甜菜育种材料根据生产率和技术质量的综合评估，选择了四个简单的和六个试验的杂交品种，这些杂交品种的糖含量高且预测的糖产量高，甜菜根产量和白糖产量超过或达到小组标准的水平。试用混合编号。1262和1264值得特别关注，因为它们的含糖量超出了组标准的绝对值分别为0.55和0.60％，预测的工厂糖产量分别为0.48和0.63％绝对值，甜菜根产量为6.89和22.77％，白糖产量为10.10。和27.69％。选择的有前途的甜菜杂交种被建议育种者作进一步的工作。
