( 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( Capsicum frutescens L. ) 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 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;生物学特性;遗传 中图分类号S641. 3 文献标识码A 文章编号0517 - 6611( 2011) 08 - 04467 - 03 Study on Biological Characteristics and Itrinsic Genetic Law of Potted C. frutescens L.

Plants,and their height were 15. 1,15. 1 and 27. 2 cm respectively,their width were 29. 5,29. 2 and 39. 6 cm respectively. The P08 - 1's fruit colour changed from purple to orange,finally turned into red,the P08 - 3's fruit colour changed from milkiness to orange,finally turned into red, and the P08 - 4 's fruit colour changed from milkiness to orange,finally turned into red. The P08 - 2's height and width were all 42. 6 cm,fruit colour changed from purple to green,finally turned into red. P08 - 1,P08 - 2 and P08 - 4 did not separate out other plant in self - descendants, P08 - 3 separated out plant which fruit was not purple. P08 - 1,P08 - 2 and P08 - 4 seed germination rate for the second generation were 100. 0%,93. 3%,93. 3% respectively,P08 - 3's was 78. 8%.
