Increasing performance of ALS inhibitor herbicide tolerant beet plants by combining optimally adapted ALS large and small subunits

Provided are improved herbicide tolerant beet, in particular improved sugar beet plants, with improved yield performance while maintaining optimal and agronomically related herbicide tolerance in which the large and small subunits of herbicide tolerant acetolactate synthase are optimally adapted. Also provided are markers for identifying such improved herbicide tolerant beet plants, as well as methods for obtaining and identifying such improved herbicide tolerant beet plants. 提供了改良的除草剂耐受性甜菜，特别是改良的糖用甜菜植物，其具有提高的产量性能，同时保持最佳且农艺相关的除草剂耐受性，其中除草剂耐受性乙酰乳酸合酶的大亚基和小亚基被最佳地适配。还提供了用于鉴定这样的改良的除草剂耐受性甜菜植物的标志物，以及用于获得和鉴定这样的改良的除草剂耐受性甜菜植物的方法。
