Two complementary factors,
The existence of a number of modifying factors affecting the degree of expression of the “crumpled” character has been demonstrated.
It was not possible to correlate either
Examination of sections from near the growing point of a “crumpled” seedling revealed no marked abnormalities.

A series of six multiple allelomorphs controlling the distribution of anthocyanin pigmentation has been demonstrated in Asiatic cottons. The symbols,
Red, the highest member of the series, has been shown to be dependent for its full expression on the presence of
The presence in the
The bearing of the distribution of anthocyanin genes and their modifiers on the classification of the cultivated Asiatic cottons has been discussed, and conclusions similar to those drawn in previous papers (Hutchinson, 1931, 1932

1. Tufted seed (
2. The identity of the gene for tufted with that for semi-tufted is established.
3. The modifying factors responsible for the difference between tufted and semi-tufted cause the heterozygote to be almost or completely indistinguishable from fuzzy, and are the same as those responsible for the difference between thick and thin fuzz on fuzzy seeds. One of these modifiers is located in the brown lint—leaf shape linkage group.
4. Fuzz modifiers, but not the main tuft factor, affect slightly the hairiness of the plant body.
5. A long lint factor and a seed weight multiple allelomorph series are located in the same chromosome as the tufted factor. There were no other association between lint characters and fuzz characters.
6. The tufted factor and the lintless factor are independent.
7. Tufted associated freely with: leaf shape, anthocyanin pigment, corolla colour, lint colour (3 factors), leaf nectaries.
8. No satisfactory evidence of linkage was obtained between the lintless factor and leaf shape, anthocyanin pigment, corolla colour, leaf nectaries.

Seven types of lintless occurring in Asiatic cottons are described. It is shown that at least four independent genes are involved. Two of these are complementary genes for glabrous lintless and two complementary genes for hairy lintless.
The relationship of the
The linkage relations of the lintless genes were studied, but no satisfactory evidence of linkage was found. There was, however, a strong association between
