Agricultural expansion and the need for sustainable cultivation are challenges faced by researchers involved in the generation of new cultivars that can adapt to abiotic stress. Knowledge of the genetic effects of characteristics related to efficiency and responsiveness to phosphorus use must be considered when implementing methods to obtain better genotypes. The aim of this study was to characterize and select popcorn hybrids based on their efficiency and responsiveness to phosphorus use, and estimate their combining abilities and genetic effects via diallel analysis to implement improvement programs for sustainable agriculture. Eight contrasting inbred lines were used to obtain simple hybrids for diallel analysis. Twenty-eight diallelic hybrids plus the popcorn parental lines were evaluated at two different sites under two contrasting environments for soil phosphorus availability (6×6 lattice design). Grain yield, popping expansion, and volume of expanded popcorn per hectare were measured. A combined analysis of variance and a test of means were performed. The classification and utilization of the phosphorus use efficiency index, according to the grain yield performance of the hybrids under contrasting environments, was considered. Through model 2 of the Griffing?s diallel analysis method, the general and specific combining abilities were estimated, along with their environmental interactions. The best strategy to obtain genotypes that are efficient and responsive to phosphorus involves exploring popcorn hybrids using genitors that result in the accumulation of additive genes that promote popping expansion. Hybrids P7×L80, P7×L59, P7×L76, and P6×L80 presented promising results and may be evaluated as cultivation options in phosphorus-deficient soils.

A Embrapa comemora 49 anos de sua criação, esta edição do Balanço Social completa 25 anos de existência, registrando boa parte das contribuições da Empresa à sociedade. Trata-se, portanto, de um marco na sua história. Publicado desde 1997, o Balanço Social testemunha o impacto das principais tecnologias desenvolvidas e transferidas à sociedade. Nestes anos, apuramos um lucro social acumulado e corrigido pelo Índice Geral de Preços-Disponibilidade Interna - IGP-DI (FGV) de R$ 1,2 trilhão. São raças de animais bastante prolíficas ou adaptáveis aos mais diversos ambientes; de novas máquinas, equipamentos e sistemas de produção; de cultivares mais produtivas, nutritivas ou resistentes a pragas e intempéries; de sistemas de informação geográfica para mapear regiões e monitorar o uso da terra; de programas e aplicativos de informática; de novos processos de cultivo, de produção animal e controle de pragas e doenças. |
