【摘要】 植物育种计划的制定基于多样性和优良的数量及质量性状的选择。因此,遗传多样性的评估是每个植物育种计划的第一步。本文概述了甜菜种质资源在形态学水平、细胞学水平、生化水平尤其DNA水平(RAPD、SSR、ISSR、SRAP、ISSR和SNP等分子标记)上的遗传多样性研究进展,并展望了甜菜种质资源未来的研究方向。更多还原

【Abstract】 Plant breeding programs are worked out based on the diversity and selection of superior quantitative and qualitative traits. Hence, assessment of genetic diversity is the first step of every plant breeding program. In this paper, the research progress of genetic diversity of beet germplasm resources in morphology, cytology, biochemistry biochemistry, especially DNA level(molecular markers such as RAPD, SSR, ISSR, SRAP, ISSR and SNP) were summarized, and the future research direction of beet germplasm resources was prospected.更多还原
