—Beta vulgaris ssp. maritima is a facultative perennial species exhibits large intraspecific variation in vernalization requirement. Bolting tendency is a complex character governed by various environmental cues and multiple genetic factors. A panel of B. vulgaris ssp. maritima accessions collected from the Mediterranean costs revealed significant variations in bolting time. Three F2 populations derived from crosses between six annual beet accessions were analyzed for bolting behavior. Two F2 segregated populations, i.e., Bvm127 and Bvm128 exhibited phenotypic segregation ratios of 3 : 1 earlybolting and latebolting which is expected for dominantrecessive inheritance of a monogenic trait. Meanwhile, the phenotypic segregation ratio for early bolting: latebolting in the F2 population Bvm125 did not deviate significantly from 63 : 1, indicating a poly genic inheritance of bolting tendency in Beta vulgaris ssp. maritime. Broad sense heritability for bolting ten dency ranged from 0.58 to 0.74.
