Resumo: | The objective of this work was to evaluate the productivity and resistance to leaf rust (Hemileia vastatrix Berk. & Br.) of twenty four F4 coffee progenies from crosses between the Icatu and Catimor cultivars. The experiment was carried out in Três Pontas, Minas Gerais State, in a randomized block design with four repetitions and 25 treatments. The Rubi MG 1192 cultivar was used as control. Coffee bean yield in bags.ha-1 from six harvests (from 2001/2002 to 2006/2007) and leaf rust incidence and severity in the first semester of 2006 were analyzed. The results indicated variability among the evaluated progenies, mainly for grain yield and rust resistance, as confirmed by herdibility traits, which showed a broad range of 31,5% for grain yield and up to 92,8% for rust incidence. This condition, associated with high bean yield, which reached 31,9 bags.ha-1, and with low rust incidence and severity demonstrated the possibility of selecting outstanding progenies from among the studied population, which potentially can be used as productive and commercial cultivars resistant to leaf rust. |

As progênies foram avaliadas em experimento instalado em Três Pontas, sul do Estado de Minas Gerais na Fazenda Experimental da Epamig. O delineamento foi em blocos casualizados com quatro repetições e 25 tratamentos, 24 progênies do cruzamento mais a cultivar Rubi MG 1192 como testemunha. Para a análise dos dados, adotou-se o esquema de parcela subdividida no tempo. Foram analisadas as características: produção em sacas beneficiadas.ha-1 de seis colheitas: 2001/2002 a 2006/2007 e a incidência e a severidade da ferrugem no primeiro semestre de 2006. Pelos resultados obtidos, verifica-se que as progênies avaliadas apresentam variabilidade, principalmente para a resistência à ferrugem, confirmado pelas estimativas da herdabilidade, que foram de boa magnitude, chegando até o valor de 92,8% para a característica incidência da ferrugem. Essa condição, aliada às médias altas de produção, que chegaram até a 31,9 sacas.ha-1 na média das seis colheitas, à baixa incidência e severidade da ferrugem, demonstrou que é possível selecionar progênies superiores na população estudada, com potencial de serem lançadas como cultivares produtivas e resistentes à ferrugem.Editora UFLA2007-12-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/34Coffee Science - ISSN 1984-3909; Vol. 2 No. 1 (2007); p. 10-19Coffee Science; Vol. 2 Núm. 1 (2007); p. 10-19Coffee Science; v. 2 n. 1 (2007); p. 10-191984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporengspahttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/34/30https://coffeescience.ufla.br/index.php/Coffeescience/article/view/34/114https://coffeescience.ufla.br/index.php/Coffeescience/article/view/34/115Copyright (c) 2007 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessBotelho, César EliasMendes, Antonio Nazareno GuimarãesCarvalho, Samuel Pereira deCarvalho, Gladyston Rodrigues deGonçalves, Flávia Maria AvelarCarvalho, Alex Mendonça de2013-02-23T12:29:20Zoai:coffeescience.ufla.br:article/34Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:27.206881Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
