摘要
对54份中国特有小麦的干种子、花药及未成熟种子的酯酶同工酶分析表明:酯酶在这些材料中存在组织特异性。54份材料具有12种酶谱类型,在新疆小麦中具有特殊的2A 标记带。聚类分析结果表明,云南小麦和西藏半野生小麦亲缘关系相近,进化水平相同,属一种类型;普通小麦与西藏普通小麦属一种类型;新疆小麦单为一种类型,具有自己独特的进化途径。
Esterase isozyme of dry seeds,anthers and immature seeds from 54 accessions of indige- nous wheat to China was analysed.The result showed the specialties of esterase isozyme in different tissues.There were 12 zymogram types of esterase isozyme in 54 materials.A spe- cial marked band,esterase isozyme band 2A,was found in Xinjiang wheat.Cluster analy- sis suggested that (1) Yunnan wheat was geneticaly close related to Tibet semi-wild wheat. Both of them are in the same level of evolution and belong to one taxonomical group.(2) Common wheat and Tibet common wheat belong to one group and (3) Xinjiang wheat is a spe- eial group,having its own evolutionary process.
