Inheritance of a Recessive Character Controlling Reduced Carotenoid Pigmentation in Carrot (Daucus carota L.)

this study showed tetrasomic segregation. Restriction fragment length polymorphism (RFLP) analysis of chloroplast DNA revealed that A. kantoensis was recently derived from a diploid congener A. asa-grayi (Ito 1992), which is morphologically distinct from A. kantoensis and is distributed in southern Japan. These results suggest that A. kantoensis may be derived from A. asa-grayi. In Asteraceae, other examples of tetrasomic inheritance are also known in Haplopappus spinulosus (Hauber 1986), Coreopsis grandiflora var. longipes (Crawford 1984), and Aster hispidus (Maki, Masuda and Inoue, in preparation). Tetrasomic inheritance appears to be more prevalent in Asteraceae than was previously thought.
