| 摘 要： | 对我国芦苇染色体数与产量性状的关系分析表明，在我国黄河以北１０省、区的引个芦苇品种中，通常是八倍体（２ｎ＝９６）类型的产量性状及抗性明显超过四倍体（２ｎ＝４８）类型。因此，芦苇的引种、良种繁育及新品种选育、应侧重于八倍体。在一个当地的优势种（２ｎ＝９６）中，发现有染色体众数为１１６的根尖。这一优势种单株的巨型性与该根尖染色体个数的增加有什么联系还有待研究。

| Abstract: | In 31 reed varieties from 10 provinces and districts north ward of Yellow River in China, the yield character and resistance of the octaploid(2n =96)plants were much better than those of the tetraploid (2n=48) Ones.Therefore, the octoploid seed should be first selected in the introduction, propagation and breeding of new varieties.In one native dominant species(2n=96),the roottips with 116 chromosome mode were discovered, but the relation of the giantness in the individual plant of the species with the increase of chromosome mode in its roottips is remained to be investigated. |
