Resumo: Mocó cotton (Gossypium hirsutum r. marie-galante Hutch.) grown in the Northeastern Brazil is a plant of unknown origin and only conjectures can be made about its appearance in this region. The objective of the present study was to compare 'mocó' against G. mustelinum Miers in order to contribute for the understanding of its origin and botanical classification. The study was carried out by comparing G. mustelinum against seven types of mocó cotton represented by: mocozinho, mocó-vale-do-seridó, francisco-raimundo, cream fiber, genetically improved mocó, mocó resembling G. barbadense and, mocó with tendency to G. mustelinum. The variables studied were leaf, bract and flower, which were measured in five plants selected at random before flowering. The method consisted of cluster and main components analysis, as well as of canonical discriminant analysis. The results favor the hypothesis that G. mustelinum is not the ancestor of mocó cotton grown in the Northeastern Brazil.

O objetivo do presente estudo foi comparar o 'mocó' com o G. mustelinum Miers, com a finalidade de contribuir para o esclarecimento da sua origem para a classificação botânica. O estudo foi conduzido comparando-se o G. mustelinum com sete tipos de 'mocó' representados pelos mocozinho, mocó-vale-do-seridó, francisco-raimundo, fibra creme, mocó melhorado e, finalmente pelos mocós com tendência para G. barbadense, com proximidade para o G. mustelinum. As variáveis estudadas foram tomadas nas folhas, brácteas e flores, medidas em cinco plantas selecionadas ao acaso, antes do florescimento. O método consistiu na análise de conglomerados, dos componentes principais, e na análise discriminante canônica. Os resultados favorecem a hipótese de que o G. mustelinum não pode ser considerado um dos precursores do algodoeiro mocó em cultivo no Nordeste brasileiro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFreire, Elêusio CurveloMoreira, José de Alencar Nunesdos Santos, José Wellingtonde Andrade, Francisco Pereira1998-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4994Pesquisa Agropecuaria Brasileira; v.33, n.10, out. 1998; 1555-1561Pesquisa Agropecuária Brasileira; v.33, n.10, out. 1998; 1555-15611678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4994/7142info:eu-repo/semantics/openAccess2015-01-15T19:10:14Zoai:ojs.seer.sct.embrapa.br:article/4994Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-01-15T19:10:14Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
