RESUMO
The results of genetic analysis of the wavy shoots character supported the hypothesis on the existence of two genes, Wsh1 and Wsh2, whose mutations caused wavy shoots in radish lines 16 and 26, respectively. As shown by analysis of joint inheritance with marker characters, wavy shoots were inherited independently of the biochemical markers (genes Lap1, Ep, Dia1, and Aat). Gene Wsh1 was shown to be linked to genes A, ac, and ar; the mode of inheritance depended on the cross combination. In hybrids with mutant line 16, plants with novel morphological defects, which were absent in the parental forms, were detected. Possible mechanisms of new morphological abnormalities and change of linkage in the combinations analyzed are discussed.

We characterized radish lines from a genetic collection on the basis of six enzyme systems, identified genes controlling these enzymes, and examined joint inheritance of some biochemical and morphological traits.
