ALS 저해 제초제 저항성 올챙이고랭이의 세대 유전과 발아 특성

초록

This experiment was conducted to determine whether Scirpus juncoides GS28 (R) biotype, which is resistant to the ALS-inhibiting herbicide penoxsulam, maintains resistance to the herbicide over generations and whether there is a difference in germination rate compared to HC121 (S) biotype, which is susceptible to penoxsulam. Previous research (2017) demonstrated that GS28 exhibited a considerably higher R/S ratio value than other susceptible biotype. In this experiment, the 4th generation seedlings of both GS28 and HC121 showed a similar tendency to previous studies, with R/S ratio values of 78.1:1 to penoxsulam, respectively, indicating that the resistance of GS28 persisted over generations. Additionally, GS28 showed low dormancy and a significantly higher germination rate compared to HC121, suggesting that the spread of ALS-inhibiting herbicide-resistant S. juncoides is expected when GS28 seeds are existed in the field.
