Abstract
Some male sterile plants were found in seed fields of cauliflower, Brussels sprouts and white cabbage. In all 3 crops the male sterile flowers were characterized by shorter stamens and shrivelled anthers. Male sterility did not seem to be greatly influenced by the environment.
In cauliflower male sterility is determined by 1 recessive factor. In Brussels sprouts this characteristic also depends on recessive factors. In this crop, however, the mode of inheritance is much more complicated. In addition to completely male sterile plants there were also partially male sterile plants of Brussels sprouts.
Two plants of white cabbage were found to be male and female sterile.
