Summary: | The objective of this study was to evaluate the relative performance of 74 partially inbred lines (S4) from crosses between the commercial hybrids P30P70 and Dow8460 in topcrosses with the commercial single cross hybrid P30F53 (tester), and checks (hybrids Dow8460, P30F53 and Status). The grain yield (GY) was evaluated in two environments in Guarapuava-PR. The effects of genotypes, environments and genotypes x environments interaction were significant for grain yield (GY). Among the topcrosses hybrids (TCH) the GY ranged from 8,302 (TCH 123, in the environment 2) to 14,809 kg ha-1 (TCH 11, in the environment 1). In the environment 1 we evaluated agronomic characteristics of the forage and bromatologic characteristics of the silage. The green mass productivity (GMP) of forage ranged from 49,857 (TCH 208) to 80,642 kg ha-1 (TCH 22) and the dry mass productivity (DMP) ranged from 11,072 (TCH 217) to 24,143 kg ha-1 (TCH 22). The contents of neutral detergent fiber (NDF) ranged from 45.39 (TCH 80) to 56.71% (TCH 77) and the contents of acid detergent fiber (ADF) ranged from 25.45 (TCH 80) to 35 60% (TCH 99). The relative value of the silage (RVS) presented average ratios ranged from 103 (TCH 148) to 142 (TCH 80). For all the characteristics many topcrosses did not differ from the best checks. TCH 22 and 53 were higher considering the set of all characteristics of forage and silage and, also, it showed high grain yield, therefore, these inbred lines should be advanced in the breeding program. |

O objetivo do trabalho foi avaliar o comportamento relativo de 74 linhagens parcialmente endogâmicas (S4) provenientes do cruzamento entre os híbridos comerciais P30P70 e Dow8460 em topcrosses com o híbrido simples comercial P30F53 (testador), mais as testemunhas (híbridos Dow8460, P30F53 e Status). A produtividade de grãos (PG) foi avaliada em dois ambientes em Guarapuava-PR. Houve efeito significativo de genótipos, ambientes e da interação genótipos x ambientes quanto à produtividade de grãos (PG). Entre os híbridos topcrosses (HTC) a PG variou de 8.302 (HTC 123, no ambiente 2) a 14.809 kg ha-1 (HTC 11, no ambiente 1). No ambiente 1 foram avaliadas características agronômicas da forragem e bromatológicas da silagem. A produtividade de massa verde (PMV) da forragem variou de 49.857 (HTC 208) a 80.642 kg ha-1 (HTC 22) e a produtividade de massa seca (PMS) variou de 11.072 (HTC 217) a 24.143 kg ha-1 (HTC 22). Os teores de fibra em detergente neutro (FDN) variaram de 45,39 (HTC 80) a 56,71% (HTC 77) e os teores de fibra em detergente ácido (FDA) variaram de 25,45 (HTC 80) a 35,60% (HTC 99). Para o valor relativo da silagem (VRS) foram obtidos índices médios variando de 103 (HTC 148) à 142 (HTC 80). Para todos os caracteres houve topcrosses que não diferiram das melhores testemunhas. Os HTC 22 e 53 foram superiores considerando todo o conjunto de caracteres forrageiros e bromatológicos da silagem e, ainda, apresentaram elevada produtividade de grãos, portanto, as respectivas linhagens genitoras devem ser avançadas no programa de melhoramento.UEL2015-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1612910.5433/1679-0359.2015v36n4p2395Semina: Ciências Agrárias; Vol. 36 No. 4 (2015); 2395-2406Semina: Ciências Agrárias; v. 36 n. 4 (2015); 2395-24061679-03591676-546Xreponame:Semina.
