摘要：

为研究赏食兼用型辣椒花瓣和果实紫色性状遗传机制，以白辣观赏椒F7和紫辣观赏椒F8作亲本，构建6个世代群体(P1、P2、F1、F2、BC1、BC2)，采用目测法分析6个世代群体的花色、青熟期果色性状，研究辣椒花瓣和果实紫色性状遗传规律。结果显示，F1代辣椒花瓣和青熟期果实均表现为紫色，说明辣椒花瓣和青熟期果实的紫色对白色均为显性，F2代分离群体紫色和白色都符合孟德尔3:1的分离比例，表明辣椒花瓣和青熟期果实紫色花瓣性状各受1对显性基因控制，BC1代分离群体紫色和白色都符合1:1的分离比例；BC2代辣椒花色和果色均表现为紫色，但有颜色深浅的区别，表明控制辣椒花瓣和青熟期果实紫色的基因具有累加效应。

Abstract:

The paper aims to explore the genetic mechanism of purple characters in petals and fruits of ornamental and edible pepper. White pepper F7 and purple pepper F8 were used as parents to construct six generations of genetic families, namely P1, P2, F1, F2, BC1, BC2. The petals color and unripe fruits color of six generations were analyzed by visual observation. The genetic law of purple characters in petals and fruits were researched. The results showed that the petals color and unripe fruits color of F1 generation group were purple, indicating that the purple color of petals and fruits was dominant to white color. The purple and white individuals of F2 segregating population were in accordance with Mendel’s 3:1 separation ratio, indicating that the purple petals and fruit of pepper were controlled by one dominant gene. The purple and white individuals of BC1 segregating population were in accordance with 1:1 separation ratio. The petals color and fruits color of BC2 generation group were purple, but there were shades of color, indicating that the gene controlling purple had an additive effect.
