Resumo: | With the objective of identifying the best commercial hybrids to extract maize lines, a top cross scheme of 49 endogamic partial lines (S3) was carried out with the IA33 tester. The resultant hybrids were evaluated for grain yield, in Campinas, Mococa, and Palmital (São Paulo State, Brazil), in two agricultural years (2005/2006 and 2006/2007), in a randomized block design, with three replications, in two experiments (TC1 and TC2). Individual and group variance analysis and a grouped analysis of the experiments with common treatments were carried out, for each place. The top cross hybrids were grouped according to the line origins. Afterwards, orthogonal contrasts were carried out by using the Student’s t test, in order to compare the hybrid groups. It was verified that the use of commercial hybrids to extract lines is an interesting strategy. In general, it was also verified that the top cross hybrid groups, whose lines originated from the AG1051, Master, and XL357 hybrids, obtained high yield, with a higher potential for lines extraction. KEY-WORDS: Zea mays L.; top cross hybrids; partially endogamic lines (S3). |

Para isto, foram realizados cruzamentos, em esquemas top crosses, de 49 linhagens parcialmente endogâmicas (S3), com o testador IA 33. Os híbridos resultantes foram avaliados, quanto à produtividade de grãos, em Campinas, Mococa e Palmital (Estado de São Paulo), em dois anos agrícolas (2005/2006 e 2006/2007), utilizando-se o delineamento de blocos ao acaso, com três repetições, em dois experimentos denominados TC1 e TC2. Efetuaram-se análises de variância individuais e conjuntas e, também, uma análise agrupada do TC1 e TC2, com tratamentos comuns, por local. Os híbridos top crosses foram agrupados de acordo com a origem das linhagens. Posteriormente, foram realizados contrastes ortogonais, para comparar os grupos de híbridos, pelo teste t de Student. Constatou-se que a utilização de híbridos comerciais, para extração de linhagens, é uma estratégia interessante. Verificou-se, também, que, em geral, os grupos de híbridos top crosses, cujas linhagens foram oriundas dos híbridos AG1051, Master e XL357, obtiveram elevada produtividade, tendo, portanto, maior potencial para extração de linhagens.
