Abstract
-
1.
A genetical analysis of male-sterility in carrots was made in one set of F1's and in two sets of backcrosses.
-
2.
The individual ratios were checked on binomial probability paper of Mosteller and Tukey. In addition groups of ratios produced by crossing one male-sterile plant to various male-fertiles, or various male-steriles to one male fertile, were compared to backcross ratios as a further check.
-
3.
Eight different hypotheses were tested. The hypothesis that male-sterility in carrots is controlled by a cytoplasmic factor, two duplicate nuclear genes (one recessive, one dominant), and two complimentary dominant fertility restoring nuclear genes, proved satisfactory.
