Thirty lines of bean were tested for resistance to glyphosate in the field.Obvious difference in resistance response to glyphosate was detected when glyphosate was applied at the rate of 1kg ai/ha on the 15th day after emergence of seedlings.The ling 89-05 showed high resistance with a survival of 77%.Even after glyphosate was reapplied,the survival rats was still 20%.Obvious segregation was found in Progency of 89-05 for resistance to glyphosate;the survival rate of lined 89-05-1 89-05-2 and 89-05-3 were,respectively.42.3%,51.4% and 85.7% at 1kg ai/ha of the herbicide.Progenies 89-05-3 continued to show resistance and lines 89-05-3-5 and 89-05-3-7 both had a survival rate of 100%.When glyphosate was applied with a rate over 1kg ai/ha, the survival rate of the 89-05 -3- 5 was still between 50%-98%. 展开更多
