Genetic diversity of arboreal cotton populations of the Brazilian semiarid: a remnant primary gene pool for cotton cultivars

Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, with a few small area planted in the three.. Read More»

Diversity and genetic structure among subpopulations of Gossypium mustelinum (Malvaceae)

    M.F. Alves P.A.V. Barroso A.Y. Ciampi L.V. Hoffmann V.C.R. Azevedo U. Cavalcante

Gossypium mustelinum is the only cotton species native to Brazil; it is endemic to the semi-arid region of the northeast. The populations are found near perennial and semi-perennial sources of water, such as ponds or pools in intermittent streams. Problems with in situ conservation derive from human interference in its habitat, mainly because of excessive cattle grazing and deforestation. Estab.. Read More»

Natural hybridization between Gossypium mustelinum and exotic allotetraploid cotton species

    I.P.P. de Menezes1, J.O. da Silva1, G. Malafaia1, R.D.D. Silveira1 andP.A.V. Barroso2

Cotton has been collected in Brazil for decades for its conservation, evaluation, and the use of its genetic resources. Gossypium mustelinum is an allotetraploid cotton species that only occurs in Brazil, and little is known about its genetic potential for improvement. However, the species is threatened by habitat fragmentation and interspecific hybridization with exotic species of cotton. In t.. Read More»
