Resumo: | The present work was conducted at FCAV-UNESP, Campus de Jaboticabal, in late harvest crop time of 1991. One hundred interpopulational hybrids obtained from a top-cross between Dent Composite and Flint Composite populations were evaluated. The analyzed characteristics were: Spodoptera frugiperda damages, lodging, damaged ears percentage, and productivity. Estimates of heritability, variance between progenies and genetical gain for each character of available population were determined. Estimates of the progenies variance, like those from heritability for the different analysed characters, indicate that there is an adequate genetical variance for the utilization of that material on subsequent genetic breeding programs, though allowing genetical gains, on the following selection cycles for the characteristics: grain weight, lodging and damages caused by armyworm larvae, whereas for the other characteristics the obtained results were not satisfactory. |

Foram avaliadas 100 progênies de híbridos interpopulacionais obtidos do cruzamento em top-cross entre as populações do Composto Dentado e Composto Flint. Os caracteres analisados foram: danos de Spodoptera frugiperda, dias até o florescimento, altura de planta, altura de espiga, acamamento, porcentagem de espigas danificadas e produtividade. Determinaram-se as estimativas de herdabilidade, da variância entre progênies e do ganho genético em cada caráter da população avaliada. As estimativas da variância de progênies bem como da herdabilidade nos diferentes caracteres analisados indicam haver variância genética suficiente para a utilização desse material em programas de melhoramento genético subseqüentes, permitindo ganhos genéticos nos próximos ciclos de seleção, no que tange às características peso de grãos, acamamento e danos da lagarta-do-cartucho; com relação às demais características, não foram obtidos resultados satisfatórios.UNESP, FCAV,DEPT BIOL APLICADA & AGROPEC, CAMPUS JABOTICABAL,RODOVIA CARLOS TONNANI, KM 5, BR-14870000 JABOTICABAL, SP, BRAZILUNESP, FCAV,DEPT BIOL APLICADA & AGROPEC, CAMPUS JABOTICABAL,RODOVIA CARLOS TONNANI, KM 5, BR-14870000 JABOTICABAL, SP, BRAZILEmpresa Brasileira de Pesquisa Agropecuária (EMBRAPA)Universidade Estadual Paulista (Unesp)Tozetti, A.
