veloped Of these, one hundred and twenty-six were abnormal and six were normal. All these one hundred and thirty-two plants (normal and abnormal) were alike morphologically, i.e., they were all short, had solid straw, thin straw, and had similar head type. The presence of the six normal plants is accounted for as follows: As the abnormality was known to vary over a wide range it was thought that these six plants might be masked abnormals. So the seed was sown the next year along with seed from ten abnormal plants. The abnormality occurred among the offspring of five of the six plants to the same extent as it occurred among the offspring of the ten abnormal plants showing that they were masked abnormals. If this is so then the results of self-pollination of the abnormal plants is abnormal offspring. This has enabled the abnormality to be carried on for four generations. B. Cross-pollination. Five heads of abnormal plants were pollinated with pollen from velvet wheat. Thirty-seven grains were obtained and thirty-four plants developed. These thirty-four F1 plants were normal and had velvet chaff (a dominant character of the male parent). All the grain of these thirty-four plants was sown and 2016 F2 plants developed. Velvet chaff appeared in the proportion of three velvet to one smooth, but not a single plant of the 2016 showed any sign of the abnormality. The abnormality occurred in adjacent plots where the plants were obtained from selfed seed. The results of the breeding indicate that the character is inheritable and is recessive. It is not a simple recessive as it does not segregate in the F2. It is fairly clear that it is not due to environmental causes. The fact that it also occurred in a single plant in America suggests that it is due to a definite alteration in the chromosomal complex. The correlation of certain morphological characters with the abnormality are very suggestive of a linkage group and in view of the fact that linkage groups have not yet been definitely located in wheat this abnormality might be of importance in this direction. Further work on its inheritance is in progress.
