本文报道了尖叶芭蕉二倍体基因组的部分分子连锁图。该图谱是基于58个RFLP标记、4个同工酶标记和28个RAPD标记在92个单株的F2群体中的分离。共检测到90个位点，其中77个位点分布在15个连锁群上，13个位点独立分离。36%的位点出现偏分离，主要偏向父本。染色体结构重排被认为是这些畸变的主要原因之一。利用遗传连锁数据，以进一步的遗传和进化知识的属芭蕉，以及帮助改善育种策略的设计，进行了讨论。
A partial molecular linkage map of the Musa acuminata diploid genome is presented. This map is based on 58 RFLP, four isozyme and 28 RAPD markers segregating in an F2 population of 92 individuals. A total of 90 loci was detected, 77 of which were placed on 15 linkage groups while 13 segregated independently. Segregation distortions were shown by 36% of all loci, mostly favoring the male parent. Chromosome structural rearrangements were believed to be one of the main causes of these distortions. The use of genetic linkage data to further the genetic and evolutionary knowledge of the genus Musa, as well as to help improve the design of breeding strategies, is discussed.
