应用SSR辅助选择技术选育优质蛋白糯玉米自交系
Selection of waxy-QPM maize lines with SSR markers
摘要
Abstract
Both waxy corn and Quality Protein Maize (QPM) are high quality feed and food sources.Most of the waxy corn is consumed as food in Asia for its immense nutritional and edible value,while the QPM is consumed mainly for feed purpose.However,the developmental studies have been limited due to the narrow genetic background.The present study is aimed to create a new type of corn with advantages of both,the waxy corn as well as the QPM,and to develop a new approach to expand the genetic background of QPM and waxy corn germplasm in order to meet the demand of maize breeding and production.Eighteen stable waxy-QPM lines were developed from 6 crosses combined with 2 QPM and 4 waxy lines selected through SSR marker assisted selection.The total amino acid and lysine content of most lines were improved and most of the lines were found to be preferable in terms of disease resistances,endosperm hardness,agronomic traits and lysine content.关键词
