Genetic analysis of anthracnose resistance in ‘Pitanga’ dry bean cultivar

Abstract

Anthracnose, caused by Colletotrichum lindemuthianum, is a major disease of dry bean and results great yield losses. The objective of this work was to characterize the anthracnose resistance gene present in the Andean cultivar ÔPitangaÕ. This cultivar was crossed with the cultivars Michelite, Michigan Dark Red Kidney, Cornell 49-242, Mexico 222, PI 207262, TU, AB 136, G 2333, BAT 93, SEL 1308, H1 line, Ouro Negro, Jalo Vermelho and Jalo Listras Pretas to obtain F 1 and F 2 populations. These populations were then inoculated with races 23, 64, 65, 73 and 2047 of C. lindemuthianum. The segregation ratio was 3 resistant : 1 susceptible, which shows that resistance inheritance is controlled by a single dominant gene. The results from allelism tests in fourteen F 2 populations fit a 15 resistant : 1 susceptible ratio, which indicates that the resistance present in the ÔPitangaÕ cultivar is dominant and independent from genes and alleles already characterized: Co-1, Co-2, Co-3, Co-4 2 , Co-5, Co-6, Co-7, Co-9, Co-10, Co-11, Co-12 and Co-13. The authors suggest the symbol Co-14 to represent the gene present in the ÔPitangaÕ cultivar.

Differential defence responses of susceptible and resistant kimchi cabbage cultivars to anthracnose, black spot and black rot diseases

“…Additionally, specific induction of defence-related gene expression was shown in a resistant cultivar of blueberry fruit infected by C. acutatum (Miles et al, 2011). Colletotrichum spp.-resistant cultivars have been chosen as parental lines for genetic analysis of dry bean (Gonc ßalves-Vidigal et al, 2012).…”

Genetic Characterization and Mapping of Anthracnose Resistance of Common Bean Landrace Cultivar Corinthiano

“…lindemuthianum is conditioned by 21 anthracnose resistance loci identified by the Co symbol (Kelly and Vallejo, 2004). These genes and their alleles include Co‐1 (McRostie, 1919); Co‐1 2 and Co‐1 3 (Melotto and Kelly, 2000); Co‐1 4 / Phg‐1 (Alzate‐Marin et al, 2003a; Gonçalves‐Vidigal et al, 2011); Co‐1 5 (Gonçalves‐Vidigal and Kelly, 2006); Co‐2 (Mastenbroek, 1960); Co‐3 , Co‐3 2 , Co‐3 3 ( Co‐ 9 was renamed as Co‐3 3 ; Geffroy et al, 1999; Mendéz‐Vigo et al, 2005; Alzate‐Marin et al, 2007; Rodríguez‐Suárez et al, 2008; David et al, 2008, 2009; Geffroy et al, 2009); Co‐y , Co‐z , Co‐u , Co‐v , Co ‐ x , and Co‐w (Bannerot, 1965; Fouilloux, 1976, 1979; Geffroy et al, 1999, 2008; Campa et al, 2011); Co‐4 (Fouilloux, 1976, 1979); Co‐4 2 (Young et al, 1998); Co‐4 3 (Alzate‐Marin et al, 2007); Co‐5 (Young and Kelly, 1996; Young et al, 1998; Alzate‐Marin et al, 2007); Co‐5 2 (Vallejo and Kelly, 2009); Co‐6 (Schwartz et al, 1982; Gonçalves‐Vidigal et al, 2001; Kelly and Young, 1996; Young and Kelly, 1996); Co‐7 (renamed Co‐3 5 , Pastor‐Corrales et al, 1994; Young et al, 1998, Sousa et al, 2014); co‐8 (Alzate‐Marin et al, 1997); Co‐9 (renamed Co‐3 3 ; Geffroy et al, 1999; Mendéz‐Vigo et al, 2005; Alzate‐Marin et al, 2007; Rodríguez‐Suárez et al, 2008; David et al, 2008, 2009; Geffroy et al, 2009); Co‐10 (Alzate‐Marin et al, 2003b; renamed Co‐3 4 / Phg‐3 by Gonçalves‐Vidigal et al, 2013); Co‐11 (Gonçalves‐Vidigal et al, 2007); and Co‐12 (Gonçalves‐Vidigal et al, 2008); Co‐13 (Gonçalves‐Vidigal et al, 2009); Co‐14 (Gonçalves‐Vidigal et al, 2012); and Co‐16 (Coelho et al, 2013).…”

Variabilidad patogénica de Colletotrichum lindemuthianum y resistencia en germoplasma de Phaseolus vulgaris L. de Ecuador

“…Las poblaciones del patógeno de origen andino son más virulentas con las variedades diferenciales del acervo andino, debido a la mayor adaptación de razas a cultivares de la misma región geográfica (coevolución hospedante-patógeno) (Balardin et al, 1997;González et al, 1998;Araya, 2003;Gonçalves-Vidigal et al, 2012). De manera general, esto fue observado en los resultados de este estudio, ya que las variedades diferenciales de origen mesoamericano con sus respectivos genes: Cornell 49242 (Co-2), TU (Co-5), AB 136 (Co-6), G2333 (Co-4 2 , Co-5 2 , Co-7), presentaron resistencia para todos los aislamientos analizados.…”
