Brief descriptions are presented for various ultra-violet-induced changes. Among 78 inviable types, the mutant type was recovered in F3 in 71 cases. In several instances the mutant type appeared in low ratios. This tendency was most marked in the segregations for "germless" seeds.
Male and female transmission tests were made with 24 viable mutant types. In 15 cases the male and female transmission rates were not significantly different. In the remaining nine cases male and female transmission rates were unequal, and in two instances transmission through the male gametophyte was significantly greater than through the female.
