Herança de acilaçúcares em genótipos de tomateiro provenientes de cruzamento interespecífico

Abstract: Resumo -O objetivo deste trabalho foi determinar a herança da produção de acilaçúcares em genótipos de tomateiro, em uma população segregante (F 2 ) do terceiro retrocruzamento, para Lycopersicon esculentum Mill. 'TOM-584', a partir da espécie L. pennellii 'LA-716'. A determinação do teor de acilaçúcares foi realizada com metodologia para determinação de açúcares redutores. Os dados foram utilizados para verificação da herança monogênica, sob diferentes graus de dominância (GD) presumidos, por meio do teste qu… Show more

“…Vendramim et al (2009) related that oviposition of B. tabaci biotype B was concentrated near to non glandular trichomes. On the other hand, Gonçalves et al (2007) verified that acylsugars levels were correlated with neither glandular nor non-glandular trichome densities.…”

“…In order to identify the existence of major genes and polygenes with additive effects and non-additive for all traits we used the maximum likelihood method by the statistical program Monogen v. 0.1 (Silva, 2003;Gonçalves et al, 2007).…”

“…Maluf et al, 2010;Maciel et al, 2011) that the acyl sugars from 'LA716' (S. pennellii) are the main provider of pest resistance when found in high content in the leaflets and that indirect selection for high acyl sugar content was satisfactory for obtaining tomato genotypes with pest resistance. In addition to being an important component of resistance to T. absoluta, acyl sugars have a simple inheritance (Resende et al, 2002;Gonçalves et al, 2007) that is essentially monogenic with modifier genes with additive effects, which makes their introduction particularly easy in elite tomato lines.…”
