Abstract: Provided are improved herbicide tolerant Beta vulgaris, particularly improved sugar beet plants, with increased yield performance, while maintaining optimal and agronomically relevant herbicide tolerance, wherein the large and small subunits of the herbicide tolerance acetolactate synthase enzyme are optimally fitted. Further provided are markers for identifying such improved herbicide tolerant Beta vulgaris plants, as well methods for obtaining and identifying such improved herbicide tolerant Beta vulgaris plants.

Abstract: The invention relates to a phenotyping system (1), comprising a plant unit (11) having one or more plants (17), a growing area (5), a measurement area (7), a sensor (73) located in the measurement area (5) for acquiring phene-data related to phenes of the plants (17), wherein the phenotyping system (1) is adapted to transport the plant unit (11) to the measurement area (5). The phenotyping system (1) is characterized by at least one weighing vehicle (49) comprising a weighing unit (66) for acquiring weight-data related to a weight of the plant unit (11). The invention further relates to a method for phenotyping of plants with a phenotyping system (1) in a second aspect and to a computer program for operating a phenotyping system (1) in a third aspect of the invention.
