    • Abstract


      Seven additional types of anthocyanin in cotton are described and shown to be controlled by members of an extensive allelomorph system of which fourteen members are now known in the cultivated diploid Asiatic species,Gossypium arboreum andherbaceum. All seven of the new types were found in China, six in field material, and the seventh as an anomaly in experimental cultures. The information relating to the genetical behaviour of this and similar series, whose manifold expressions do not conform to a single simple seriation, is reviewed from the standpoint of deciding between the alternative interpretations of close linkage and multiple allelomorphism with pleiotropy. Although the cotton series, in which a new ‘pattern’ arrangement appeared under controlled conditions, might have been expected to be a particularly suitable subject for this purpose, it was not possible to reach a definite conclusion on the experimental evidence.
