1、...页眉几种盆栽辣椒生物学特性及性状遗传研究朱顺莲1,龙明华2,孙立2,武鹏3(1.黔西南民族职业技术学院,贵州兴义562400;2.广西大学农学院,广西南宁530005;3.广西农业科学院,广西南宁530005)摘要[目的]研究几种盆栽辣椒(CapsicumfrutescensL.)的生物学特性及性状遗传状况。[方法]选用国外引进的4份珍稀盆栽辣椒(P08-1、P08-2、P08-3、P08-4)为试材,观察它们的生物学特性,分析它们的性状遗传并选育自交系。[结果]P08-1、P08-3、P08-4株高分别为15.1、15.1和27.2cm,株幅分别为29.5、29.2
2、和39.6cm;果实颜色变化过程分别是:P08-1由紫色到橙黄色最后到暗红色,P08-3由乳白色到有紫色晕斑到黄色最后到亮红色,P08-4由乳白色到紫色晕斑到黄色最后到亮红色。P08-2株高、株幅均为42.6cm,果实颜色变化过程为由茄紫色到绿色最后到暗红色。P08-1、P08-2和P08-4自交1、2代均未出现性状分离,P08-3自交2代出现果实无紫色晕斑的植株;P08-1、P08-2和P08-4自交2代种子发芽率为100.0%、93.3%、93.3%,P08-3为78.8%。[结论]该研究对丰富国内盆栽辣椒种质资源及盆栽辣椒新品种的选育具有积极意义。关键词盆栽辣椒;生物
