Resistência à mancha preta em populações F4 selecionadas de cruzamentos entre o amendoim cultivado e um anfidiplóide de Arachis

Abstract: Neste trabalho avaliou-se, em condições de campo, o potencial de resistência à mancha preta (Cercosporidium personatum) em plantas F4, selecionadas de cruzamentos entre genótipos de Arachis hypogaea (acessos VGaRoSv 12549 e VGaRoSv 12548 e a cultivar IAC Caiapó) e um anfidiplóide sintético (Arachis ipäensis x Arachis duranensis)4x. O experimento foi desenvolvido no ano agrícola de 2007/2008, em Pindorama (SP). Avaliaram-se noventa e três famílias de plantas em F4, em parcelas com dez plantas distribuídas em li… Show more

“…Difficulties in selection of interspecific lines for leaf spots resistance and yield had previously and simultaneously been reported (Stalker et al 1979, Ouedrago et al 1994, Santos et al 2011, leading to the use of intensive and time consuming backcross programs, in order to recover the agronomic traits profile required for market. In the present study, high yielding interspecific progenies of runner market type with seed size for different markets were identified in the first backcross generation, attesting the potential for economic exploitation of the wild species reported by Stalker et al (1979) and Fonceka et al (2012).…”

“…Several germplasm lines resistant to leaf spots, as well as lines with wild species in their pedigree, were developed and made available (Stalker and Beute, 1993;Stalker et al, 2002;Isleib et al, 2006Isleib et al, , 2011Santos et al, 2011Santos et al, , 2013Kumari et al, 2014). Currently, there are many amphidiploids available such as those developed in India and Brazil.…”

“…A produção mundial na safra 2013/2014 foi de 39,8 milhões de toneladas de amendoim com casca, com previsão de redução em 2,14% para 2014/2015 (Agrochart, 2015). Essa redução na cultura pode ser atribuída tanto a mudanças climáticas, como às doenças fúngicas foliares, que constituem fatores limitantes para a produtividade do amendoim, além de seu controle químico elevar os custos de produção (Santos et al, 2011).…”
