水稻生产上广泛使用DGWG半矮杆资源,有可能导致水稻品种的遗传脆弱性,扩大半矮杆资源遗传基础,创造新的有实用价值的半矮杆资源具有重要意义。本文分析了目前水稻矮化育种中存在的问题及人工诱变新半矮杆资源的现状。
The widespread use of DGWG semi-dang resources in rice production may lead to the genetic vulnerability of rice varieties. It is of great significance to expand the genetic basis of semi-dwarf resources and create new semi-dang resources of practical value. This paper analyzes the problems existing in the current dwarf breeding of rice and the present situation of artificial mutagenesis of new dwarf rod resources.
