| 摘 要： | 过去20余年国内外学者对苹果属植物的起源、分类、区系地理、种内和种间遗传变异等开展了广泛的研究。然而,有关苹果属植物遗传多样性形成机理迄今未见任何直接报道。作者从变叶海棠的遗传多样性及其起源,物种的居群分化及其近缘种的形成几方面重点介绍过去15a西南大学在研究变叶海棠的遗传多样性和居群分化等方面所取得的进展。我们的研究工作为进一步探索苹果属植物遗传多样性形成机理奠定了基础,并为变叶海棠珍贵基因资源的保护和利用提供了理论依据。

| Abstract: | Apple is one of the most important fruit crop in the world,and an extensive studies on the genetic diversity of Malus including origin,taxonomy,flora characteristics,intra-and interspecific variations have been carried out in the past more than 20 years.However,there still lacks of direct report about the formation mechanism of the genetic diversity in the genus Malus.The advances made at the Southwest University on the study of the genetic diversity and population differentia-tion in M.toringoides are summ... |
