Resumo: The objective of this work was to compare three testers for discrimination and evaluation of the combining ability of 49 S2 families, derived from the topcross popcorn hybrid IAC 125. Families were evaluated by their per se performance and their crosses with the testers BRS ANGELA, IAC125 and Line 3.3. The experiment was conducted in lattice design, in Maringá, PR, Brazil, during 2007/2008 cropping season. Genetic and phenotypic parameters was estimated for grain yield and popping expansion, and compared using the topcrosses between families and testers and the families per se. General and specific combining ability were estimated according the partial diallel model. Topcrosses heterosis was also evaluated, and the capacity of discriminating the families was compared among testers using the differential index from Fasoulas (1983). The tester line 3.3 was the most suitable to evaluate the S2 families in respect to grain yield and popping expansion.

As famílias foram avaliadas por seu desempenho per se e em seus cruzamentos com os testadores BRS ANGELA, IAC 125 e Linhagem 3.3. O experimento foi conduzido em látice simples, em Maringá, PR, no ano agrícola 2007/2008. Os parâmetros genéticos e fenotípicos de capacidade de expansão e rendimento de grãos foram obtidos e comparados entre si por meio das estimativas procedentes das progênies obtidas, isto é, dos topcrosses com cada testador e das famílias S2 per se. As capacidades geral e específica de combinação foram estimadas segundo o modelo de dialelo parcial. Foram avaliadas também as heteroses dos topcrosses em relação aos testadores per se, a capacidade de discriminação dos testadores comparada por meio do índice de diferenciação e desempenho proposto por Fasoulas (1983). O testador mais adequado para avaliar as famílias S2, em relação do rendimento de grãos e capacidade de expansão foi a linhagem 3.3.UEL2012-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/655510.5433/1679-0359.2012v33n3p873Semina: Ciências Agrárias; Vol. 33 No. 3 (2012); 873-890Semina: Ciências Agrárias; v. 33 n. 3 (2012); 873-8901679-03591676-546Xreponame:Semina.
