现代生物技术在亚麻育种中的应用

Application of Modern Biotechnology in Flax Breeding

为了给亚麻种质资源创新提供新的思路,推动亚麻育种研究的进一步发展,简要介绍了亚麻育种研究现状,总结了基因工程技术、植物组织培养技术和分子标记技术在亚麻育种中的应用。并提出加强远缘杂交育种研究、利用分子标记辅助选择提高杂交育种的效率和效果是亚麻育种研究的重点;建立和完善亚麻花药培养技术,是建立高效亚麻育种技术体系、培育突破性新品种的关键;建立高效的转基因育种技术体系是亚麻育种研究的重要方向。

In order to provide new ideas for flax germplasm innovation breeding, current research status of flax breeding was described and promote further development of flax briefly, and the application of gene engineering, plant tissue culture and molecular marker in flax breeding was summarized in the paper. We proposed that the emphasis of flax breeding was to strengthen the study on distant hybridization and improve the efficiency and effect of hybridization breeding by using marker-assisted selection. Establishing and perfecting an effective technical system of anther culture were the keys to establish a practical breeding technical system and breed elite new cuhivars. Furthermore, establishing an efficient genetic transformation breeding technical system was an important direction of flax breeding.
