一个与净叶黄抗赤星病基因紧密连锁的SSR标记
A SSR Marker Tightly Linked to the Resistant Gene of Jingyehuang on Tobacco Brown Spot
摘要
Abstract
In order to study the tobacco brown spot disease resistance inheritance, and genetic mapping, F2 and BC] populationsfrom a cross between Tobacco Brown Spot resistant variety Jingyehuang and susceptible variety NC82 were developed. Values ofdisease index under artificial inoculations showed that the resistant trait of Jing-yehuang was fitted additive-dominance model.Meanwhile, a further molecular study was carried out using SSR markers based on a former genetic mapping, and a SSR markerwhich was tightly linked to the tobacco brown spot resistant gene located on M linkage groups with distance of 4 cM was obtained.This marker provides useful information for molecular marker assistant selection of brown spot resistance in breeding program oftobacco.关键词
