The amount of chlorophyll-deficient and morphological abnormality genes concealed in natural populations of wild radish, <i>Raphanus sativus</i> var. <i>hortensis</i> f. <i>raphanistroides</i>, was estimated by conducting self-fertilization by means of bud pollination. The frequencies of three mutant genes, green hypocotyl(<i>g</i>), green silique(<i>gs</i>) and hairy silique(<i>hy</i>), were also estimated from the frequency of the self-pollinated lines that segregated mutant homozygotes in the S<sub>1</sub> progeny. The frequency of chlorophyll-deficient mutant alleles is within the range expected from the mutation-selection balance theory of population genetics. However, the frequencies of <i>g</i>, <i>gs</i> and <i>hy</i> are higher, on the average 20.5%, 3.6% and 10.6%, respectively, than the frequencies expected from mutation-selection balance. The frequencies did not show any systematic geographical change, nor are they correlated to any particular environmental factors. Hence, the mechanisms that maintain these mutant alleles remain unknown.<br>
