Ear rot caused by fungi of genus Fusarium (FER) is one the potentially harmful diseases to grain quality in maize. Given capacity produce mycotoxins, FER presents a risk food safety. This study sought identify parents and indicate hybrids popcorn with higher level resistance incidence severity FER. Hybrids were produced from crossing 15 lines S7 generation 5 testers. The hybrids, together five ...

Maize is one of the most important food and feed sources at worldwide level. Due to this importance, all pathogens that can infect crop harm both safety security. Fungi are in cultivated maize, Fusarium spp. families. Reduction yield production dangerous mycotoxins main effects infection. graminearum (part species complex) fungi it causative agent Gibberella ear rot (GER). The characteristics i...

The relative role of the maternal source and the filial sink in controlling the composition of maize (Zea mays L.) kernels is unclear and may be influenced by the genotype and the N supply. The objective of this study was to determine the influence of assimilate supply from the vegetative source and utilization of assimilates by the grain sink on the final composition of maize kernels. Intermat...

Identifying and using native insect resistance genes is the core of integrated pest management. In this study, 10 experimental corn, Zea mays L., hybrids and 10 inbred lines were screened for resistance to major ear-feeding insects in the southeastern Coastal Plain region of the United States during 2004 and 2005. Ear-feeding insect damage was assessed at harvest by visual damage rating for the...

Maize is a socioeconomically important crop in many countries. Recently, a high incidence of stalk rot disease has been reported in several maize fields in Gangwon province. In this report, we show that maize stalk rot is associated with the fungal pathogens Fusarium subglutinans and F. temperatum. Since no fungicides are available to control these pathogens on maize plants, we selected six fun...

BACKGROUND Within-field multiple crop species intercropping is well documented and used for disease control, but the underlying mechanisms are still unclear. As roots are the primary organ for perceiving signals in the soil from neighboring plants, root behavior may play an important role in soil-borne disease control. PRINCIPAL FINDINGS In two years of field experiments, maize/soybean interc...

Maize (Zea mays L.) is one of the most important crops in the world. In this study, 13 agronomic traits of a recombinant inbred line population that was derived from the cross between Mo17 and Huangzao4 were investigated in maize: ear diameter, ear length, ear axis diameter, ear weight, plant height, ear height, days to pollen shed (DPS), days to silking (DS), the interval between DPS and DS, 1...
