Resistência de linhagens de feijoeiro a quatro raças de Uromyces appendiculatus isoladas em Minas Gerais, Brasil

Abstract: A identificação de fontes de resistência é uma etapa básica em programas de melhoramento que visam o desenvolvimento de cultivares resistentes a doenças. Neste trabalho, foram inoculadas, sob condições controladas, oito linhagens de feijoeiro-comum (Phaseolus vulgaris) desenvolvidas pelo Departamento de Agricultura dos Estados Unidos, com quatro raças conhecidas de Uromyces appendiculatus coletadas no estado de Minas Gerais, Brasil. A cultivar Ouro Negro foi utilizada como padrão de resistência e US Pinto 111 … Show more

“…The resistance gene blocks present in line B-190 and in cultivar Ouro Negro are very similar and probably map to the same location. Both confer the same type of resistance, with immunity to certain U. appendiculatus races and small pustules (< 0.3 mm in diameter) to other races (Haley et al, 1993;Faleiro et al, 1999a). Interestingly both Ouro Negro and B-190 are highly productive black seed cultivars.…”

“…The molecular markers identified in this work are currently being used for the selection of diseaseresistant plants in the commom bean breeding program of the Federal University of Viçosa. (Faleiro et al, 1996), whereas cultivar US Pinto 111 is considered to be universally susceptible to rust.…”

“…Esse é o caso da cultivar Pérola, uma das mais cultivadas no Brasil. Esta cultivar é referência quanto à produtividade e qualidade de grãos, porém é suscetível às principais raças de C. lindemuthianum e U. appendiculatus predominantes nas regiões produtoras de Minas Gerais (Lanza et al, 1997;Faleiro et al, 1999). A cultivar Ouro Negro, do grupo preto, desde seu lançamento em 1991 (Araújo et al, 1991), tem-se destacado como resistente às raças 73, 81 e 89 de C. lindemuthianum e a várias raças de U. appendiculatus (Faleiro et al, 2001).…”

“…To this purpose it uses different progenitors like cultivars Rudá and Ouro Negro. Rudá, originated from CIAT, is a "carioca-type" cultivar, with growth habit IIb (semi-climber), high yielding but susceptible to several fungal diseases such as rust (Faleiro et al, 1996(Faleiro et al, , 1999a, anthracnose (Lanza et al, 1997) and angular leaf spot (Nietsche, 1997). Cultivar Ouro…”

“…Crop Breeding and Applied Biotechnology, v. 2, n. 4, p. 507-514, 2002 Negro (formerly Honduras 35), has black seeds, growth habit IIIb (prostrated or semi-climber), is highly productive, resistant to rust (Faleiro et al, 1996(Faleiro et al, , 1999a, anthracnose (Lanza et al, 1997), angular leaf spot (Nietsche, 1997;Faleiro et al, 2001b), and besides, it has excellent cooking qualities (Araújo et al, 1991). The BIOAGRO/UFV Program developed a RIL population with 154 lines from a cross between Rudá and Ouro Negro.…”
