The genetics of cotton - Part VII. “Crumpled”: A new dominant in Asiatic cottons produced by complementary factors
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 eitherA orB with any character in normal plants.
Examination of sections from near the growing point of a “crumpled” seedling revealed no marked abnormalities.
