Mean values (and standard error) from the phenotyping of 13 sugar beet lines assessed for the number of bolting plants and the number of survived plants post-winter.

Name	Number of individuals before winter	Number of plants that survived post winter	Number of bolters
L14	750	296 ± 6	12 ± 2
L8	750	221 ± 9	26 ± 4
L3	750	219 ± 4	51 ± 3
L5	750	73 ± 12	6 ± 2
L13	750	67 ± 9	11 ± 3
L12	750	76 ± 11	42 ± 2
L6	750	64 ± 12	64 ± 2
L1	750	75 ± 5	75 ± 6
L4	750	77 ± 4	77 ± 2
L7	750	72 ± 3	72 ± 3
L11	750	70 ± 4	70 ± 5
L9	750	71 ± 8	71 ± 3
L2	750	67 ± 6	67 ± 4

L14 was identified as the line combining the highest survival percentage with the lowest bolting percentage post-winter.
