摘要
研究了玉米紫色果皮、紫色胚尖、紫色盾片等直感性状的遗传及这些遗传标记在无融合生殖研究中的应用．结果是：①这几个直感性状紧密连锁．在矮广１０，ＯＨ４３，３３０，紫株玉米等３种遗传背景下表现隐性上位控制的显性、独立显性和隐性遗传；②讨论了遗传标记方法在无融合生殖研究中的应用：测定某一现象的无融合生殖性；广泛测定品种的无融合生殖性；研究已证明的无融合生殖性的遗传；
This paper reports the inheritance of xenie traits covering purle testa, purle embryo and purle scutellum in maize seeds as well as the utilization of these traits as genetic markers to appomixis research The results indicate that : 1 The xenie traits are in genetically close linkage and show recessively epistatic dominance or independent dorminance or recesive under three different genetic baekground involving Aiguang 10, OH 43 ,330 and “Zhizhu” maize inbred line; 2 It is possible to widely use the xenie traits as genetic markers to test the existence and inheritance of appomixis in maize varieties In addition,such markers should be useful for the tramsferring appomixis charaeter into cultivar from wild species
