interploid hybridization system requires tetraploids that are either selected among existing cultivars or induced from diploids by chromosome doubling ( Datta et al., 2020 ; Fetouh et al., 2020 ; Vining et al., 2012 ). In addition to sometimes lengthy and
chromosome doubled clone of 88/124–46, which was selected in 1987 and sawn in 1988) and the cultivar TANca (Caramba). The diploid genotype 88/124–46 is the product of selection after three generations of open pollination from a cross of a tetraploid cultivar
