The amino acid patterns of the seed proteins and the fatty acid patterns of the seed oils of twenty-five species of Gossypium are reported. A genome specific pattern was not found for either the amino acids or the fatty acids or for the seed index. G. anomalum differed markedly from the other species in its seed oil; the kernel contained 74·8 per cent oil and the oil contained about 20 per cent of the fatty acid having an equivalent chain length of 19·6 which was not present in the seed oil of any of the other species. The gossypol content of the defatted seed meals ranged from 0·12 and 0·13 for G. stocksii and G. incanum to 9·25 per cent for G. klotzschianum (var. davidsonii ), and a multiple range classification of the species in accordance with the gossypol content groups the species into specific genomes, with exception of G. gossypioides and G. longicalyx which seem to be out of place. I.r. spectra of the acetone-hexane-water extracts of hexane-defatted meals showed specific differences among the species and led to the grouping of the twenty-five species into their specific genomes; exceptions were G. gossypioides, G. longicalyx and G. tomentosum . |
