摘要
马铃薯 Y病毒对东北烟区烟草生产危害日趋严重。通过病圃发病情况调查和温室接种鉴定 ,初步筛选出 CV91、8741 4、80 2 1三份常规抗马铃薯 Y病毒材料 ,其中 CV91在田间调查和温室接种鉴定中均表现为高抗马铃薯 Y病毒 ;转基因抗马铃薯 Y病毒材料 85- 2、86- 1、87- 2、89- 1、94- 1、95- 1、98- 1温室接种鉴定结果为对 PVY免疫。利用 CV91育成了中抗 PVY的新品系 91 1 1 -2
The loss caused by potato virus Y (PVY) is becoming more and more serious in tobacco production in Northeastern China.Some disease resistant flue cured tobacco varieties(or lines) which were developed with common methods and biological engineering (transgenic) methods were identified by test of disease plot in field and artificial innoculation with PVY in greenhouse.The results showed that three common lines CV91,87414 and 8021 were resistant to PVY,and CV91 was high resistant.The transgenic lines 85 2,86 1,87 2,89 1,94 1,95 1 and 98 1 were immune to PVY.9111 21,a new moderate resistant line of flue cured tobacco, had been selected.
