Abstract
1. Some individuals of the spiral tortion at the leaf-stalk and the stem appeared unexpectedly at the rate of about one to three normal individuals in F2 of a crossing, in spith of the fact that such character was not exhibited in F1 and its parents.2. It was confirmed by raising of F3 the fact that this character behaves to the normal as a Mendelian recessive. This abnormal individual may be probably a mutant.3. Unless the factor (tw) for this character exists in same zygote with p for “Kudyaku” leaf, this character seems to be unable to reach its full development, though sometimes it develops slightly in the case of Ptw.4. The cross-over percentage between tw and p may be 25.5. There are individuals characterized by the bearing of the flower at the apex of the flower-branch having some leaves, in addition to the fact that the bract is abnormal on account of being large as the normal leaf.6. These characters owe to a factor which acts as a recessive to the normal. Then, the hybrid between normal bract-plants and the abnormal segregetes both normal and abnormal offsprings in the ratio of 3:1 in F2, but such cases that the segregating ratio of the abnormal bract is law, were in F3 and F2 of some crossings.7. The cross-over percentage 33, 33 may take place between a factor (a) for this character and a factor (k) for “Tombo” leaf.

Claim · model-written summary
Some plants bore an apical flower on a leafy flower branch and had enlarged abnormal bracts.
Verbatim

t0“Morning Glories”
Claim · model-written summary
The abnormal bract characters were attributed to a recessive factor.
Verbatim
e0“These characters owe to a factor which acts as a recessive to the normal.”
