Abstract
The successful transference of a hairiness gene, H6 from the wild diploid G. raimondii to G. hirsutum race punctatum has been described. Its usefulness as hairiness gene for jassid resistance is considered to be less important than its value as a marker of a D5 genome chromosome segment introduced into the cultivated tetraploid cottons. New commercially useful variability may be obtained from the introduced segment.
The presence in the D genome of a hairiness gene similar in its effects as H1 of the A genome suggests the possibility that these are homoeologous genes.
