Provided are improved herbicide tolerant Beta vulgaris hybrid plants and parts thereof, particularly improved hybrid sugar beet or fodder beet plants, with increased yield performance, while maintaining optimal and agronomically relevant herbicide tolerance, wherein both parent plants are derived by introgression of the herbicide tolerance gene from a single herbicide resistance donor genotype. Further provided are Beta vulgaris parent plants useful for obtaining such hybrid plants, markers for identifying such improved herbicide tolerant Beta vulgaris plants, as well methods for obtaining and identifying such improved herbicide tolerant Beta vulgaris hybrid plants. L'invention concerne des plantes hybrides beta vulgaris tolérantes aux herbicides améliorées et des parties de celles-ci, en particulier des betteraves à sucre hybrides améliorées ou des plantes de betterave fourragère, présentement une performance de rendement accrue, tout en maintenant une tolérance aux herbicides optimale et agronomiquement pertinente, les deux plantes parents étant dérivées par introgression du gène de tolérance aux herbicides à partir d'un seul génotype donneur de résistance aux herbicides. L'invention concerne en outre des plantes parents de beta vulgaris permettant d'obtenir de telles plantes hybrides, des marqueurs pour identifier de telles plantes beta vulgaris tolérantes aux herbicides améliorées, ainsi que des procédés pour obtenir et identifier de telles plantes hybrides de beta vulgaris tolérantes aux herbicides améliorées.
