An analysis of cotton remains from Huaca Prieta on the north Peruvian coast, dating from circa 2500 B.C. to circa 750 B.C., indicates that they were probably primitive forms of G. barbadense L. and similar in most features to those previously examine

A new method of estimating cotton fiber dimensions is developed, based on the geometrical properties of a loosely-coiled fiber. The theoretical principles are supported by experimental studies based on actual microscopic measurements of a wide range

Seeds, fiber samples, and boll parts recovered from 4 pre-ceramic sites in the Ancon-Chillon area of Peru were compared with those of living forms, both wild and cultivated, collected from the coastal areas of Ecuador and Peru. All the living forms b

A statistical analysis of fiber properties in 56 research cotton samples and 54 primitive rate stocks of Gossypium hirsutum showed that percent elongation E 1 was positively associated with fiber diameter and negatively associated with fiber wall thi

Patterns of anthocyanin development in the vegetative and floral parts of New World cotton species are determined by the actions and interactions of two genetic loci with a minimum of three alleles in each:R 1,R 1 D ,r 1, andR 2 v ,R 2,r 2. The most

Observations made over the last fifteen to twenty years have discovered no primitive forms of G.barbadense L. orG. hirsutum L. (other than G.hirsutum racelatifolium Hutchinson) which are capable of flowering during the long summer days of temperate l
