【摘要】 DNA分子标记是继形态标记、细胞标记和生化标记之后发展起来的一类重要的遗传标记,已在生命科学领域中广泛应用。本文介绍几种DNA分子标记的原理,综述了DNA分子标记在玉米种质遗传多样性鉴定、绘制指纹图谱、杂种优势类群划分和杂种优势预测等方面的应用,并探讨了在玉米种质研究中存在的问题和应用前景。更多还原

【Abstract】 Compared with morphological markers, cytological markers and biochemical markers, molecular markers have a series of advantages. Therefore they have been extensively application in life science. The principles of several DNA Molecular markers and their application on assessment of germplasm genetic diversity, fingerprinting construction, classification of heterotic groups and heterosis prediction for maize were reviewed. The present problems and prospective of molecular markers application in germplasm resource were evaluated.更多还原
