摘要
通过20多年对中国甜菜种质资源搜集、整理、繁种、编目及入库保存等方面进行科技攻关研究,弄清了目前我国甜菜中期库保存种质资源的植物学形态特征特性及遗传多样性的丰富程度,根据对已经编目入国家种质长期库的1382份甜菜种质资源材料的主要经济性状鉴定试验结果是:中国甜菜种质资源的块根产量、含糖率和产糖量均以西北生态区最高,华北生态区次之,东北生态区最低,同时其变异幅度也比较大。由此表明我国甜菜不同生态区保存的甜菜种质资源材料具有相当高的异质性和丰富遗传基础。这将有利于推动我国甜菜科研及育种事业的可持续发展。
According to tackling key problems of science and technology to the collection, sorting, seed reproduction, list and safe savings of beet germplasms for 20 years, the phytological morphologic character and genetic diversity of beet germplasm resources were made clear in middle-term beet storage in China. The appraisal results of main economic character of 1382 beet germplasms showed that the root yield, sugar content and sugar yield of beet in the northwest ecological region were superior to others, that in the north China region was middling, that in the northeast region was inferior. Variance ranges of the characters were great. The indicated＇ that the beet germplasms preserved in different ecological regions have great heterogeneity and abundant hereditary basis, it will be beneficial to sustainable development of scientific research and beet breeding.
