The genetics of cotton. Part IV. The inheritance of corolla colour and petal size in Asiatic cottons
-
Volume 25 Issue 3 April 1932 pp 281-291
Two complementary factors,
A andB , causing abnormal development have been demonstrated in Asiatic cottons.A has been found in two strains ofG. Nanking var.soudanensis obtained from the Sudan.B has been found in seventeen varieties ofG. arboreum, G. Nanking, G. herbaceum andG. obtusifolium , and in a strain ofG. Stocksii from Sind.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
A orB with any character in normal plants.Examination of sections from near the growing point of a “crumpled” seedling revealed no marked abnormalities.

The genetics of cotton - Part VIII. The inheritance of anthocyanin pigmentation in Asiatic Cottons
A series of six multiple allelomorphs controlling the distribution of anthocyanin pigmentation has been demonstrated in Asiatic cottons. The symbols,
R, R 1, Rc, Rs, ro, andr g are proposed for them.Red, the highest member of the series, has been shown to be dependent for its full expression on the presence of
Y , the gene for yellow corolla.The presence in the
R chromosome of genes affecting lint length and seed weight, has been demonstrated. These genes have been shown to be responsible for only a small proportion of the variations observed in lint length and seed weight.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
a ) have been arrived at.The
R series of multiple allelomorphs has been found to segregate independently of theY series, and ofA , one of the two complementary genes for “crumpled.” -

Gossypiums -
Volume 31 Issue 3 October 1935 pp 451-470
1. Tufted seed (
T ) is shown to differ in a single gene from fuzzy (t ), giving an intermediate heterozygote.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.

The genetics of lintlessness in Asiatic cottons
J. B. Hutchinson P. D. Gadkari
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
Li c gene carried by Punjab H.L. to the rest has not been fully worked out, and it remains to be seen whether it is the same as one of the hairy lintless complementary pair. Data are presented to show that the hairy lintless homozygoteli c-li c shown by Afzal & Hutchinson (1933) to be a lethal is now fully viable both in the original strain and in a hybrid with Narrow kokati. The probable cause of the change and its bearings on Fisher’s theory of the origin of dominance are discussed.The linkage relations of the lintless genes were studied, but no satisfactory evidence of linkage was found. There was, however, a strong association between
Li c and leaf shape in segregating families in which considerable mutation from narrow to broad leaf had occurred. This association could not be ascribed to linkage. -
