Resumo: Some upland cotton (Gossypium hirsutum L.r. latifolium Hutch.) lines developed by the Centro Nacional de Pesquisa de Algodão (CNPA) were tested together with cultivars developed by CNPA and by other research institutions in the country. Seed cotton yield was studied utilizing data from the regional cotton variety tests. Seeds were planted in a complete randomized block design with nine treatments and eight replications. The test was  conducted at 21 different localities of Northeast of Brazil, in 30 experiments in the period of two years: 1980/81 and 1981/82- The cultivar BR 1 and lines CNPA 77-149, CNPA 77-150 and CNPA 76-6873 had the highest seed cotton yield; the last one was the most productive with an average of 1,457 kg/ha in 21 out of the 30 experiments, surpassing the two control varieties BR 1 and IAC 17 by 8% and 15%, respectively.

Observou-se o aspecto de rendimento de algodão em caroço, utilizando-se os dados fornecidos pelos ensaios regionais de linhagens e cultivares de algodoeiro herbáceo delineados em blocos ao acaso, com nove tratamentos e oito repetições e conduzidos em 21 diferentes localidades do Nordeste do Brasil, num total de 30 experimentos, nos anos agrícolas 1980/81 e 1981/82. A cultivar BR 1 e as linhagens CNPA 77-149, CNPA 77-150 e a CNPA 76-6873 apresentaram as maiores médias de rendimento em algodão em caroço, mormente esta última, que, participante em 21 dos 30 ensaios, apresentou uma média geral de 1.457 kg/ha, produzindo cerca de 8% e 15% mais que as testemunhas BR 1 e IAC 17, respectivamente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantana, João Cecílio Farias deSantos, Elton Oliveira dosNeto, Miguel BarreiroCrisóstomo, João RibeiroCalvacanti, Fernando BezerraCosta, Joaquim Nunes daGomes, Ivan Ferreira2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14657Pesquisa Agropecuaria Brasileira; v.21, n.1, jan. 1986; 43-51Pesquisa Agropecuária Brasileira; v.21, n.1, jan. 1986; 43-511678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14657/8340info:eu-repo/semantics/openAccess2014-10-16T19:47:01Zoai:ojs.seer.sct.embrapa.br:article/14657Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-16T19:47:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
