| 摘 要： | 通过水稻两个杂交组合三个性状的遗传特点和相互关系的研究，表明水稻酯酶同工酶１２Ａ，过氧化物酶１５Ａ和叶鞘颜色分别受三个基因位点（ＥＳｔ—３，Ｐｏｘ—４和Ｐｓｈ）控制。三个性状间存在明显的连锁关系。三点测交结果表明，控制上述三个性状的基因间的排列顺序是Ｐｓｈ～Ｅｓｔ—３～Ｐｏｘ—４。基因间的遗传距离为，Ｐｓｈ～Ｅｓｔ—３之间５．６，Ｅｓｔ—３～Ｐｏｘ—４之间１３．５．

| Abstract: | The genetic characteristics and interrelations were studied of 3 characters of 2 cross combinations in the present paper.The experimental results showed esterase isozyme 12A,peroxidase isozyme 15A and leaf sheath colour of rice were determinated by 3gene loci(Est-3,Pox-4 and Psh) separately.There were evidently the linkage relation among 3 characters.The result of three-point test indicated,the arrangement sequnence of 3 loci controlling 3 characters was Psh-Est-3-Pox-4.The distance between each 2 loci as follows:5.6 between Psh-Est -3,13.5 between Est-3-Pox-4. |
