摘要
以1986-2012年36个烤烟品种为材料,研究了我国主栽烤烟品种的亲缘关系和亲本来源,对主栽品种的历史演变与现状、品质性状和抗病性的系谱组成以及育种途径和方式进行了分析。结果表明:品种单一、遗传基础狭窄、品质与抗性不能兼顾是我国主栽烤烟品种存在的主要问题;在我国烤烟育种的种质资源、育种目标等方面提出了建议。
Genetic relationship and parental sources of major flue-cured tobacco cultivars in China were studied based on data of 36 major cultivars during 1986-2012. History of evolution, current status, accuracy of pedigree and disease resistance of quality traits were analyzed as well as breeding approaches and methods. Results revealed that the problems of major flue-cured tobacco cultivars in China were lack of genetic diversity and combination of quality traits and disease resistance. Suggestions were made on germplasm utilization in tobacco breeding were suggested.
