Jan 14, 2023 · In recent years, YPM has become the most destructive maize pest in the Huang-Huai-Hai summer maize region of China via the tunneling of larvae into maize ears. Interestingly, YPM infestation aggravates the occurrence of maize ear rot and causes heavier yield loss of maize in the field.

Native Americans planted it alongside beans and squashes in the Three Sisters polyculture. The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ears. The ears yield grain, known as kernels or seeds.

In this study, 20 ear-related traits, including size, shape, number, and color, were obtained in 407 maize inbred lines at two sites using a high-throughput phenotypic measurement method and system.

Fungus can enter through wounds to stalk or ear; ear rot is caused by the fungus infecting silks and moving down through the ear; fungus survives on corn debris in soil and on debris of other host plants such as wheat.

Eggs, about half the size of a pinhead, are an off-white to yellowish color, and dome-shaped with ribs converging on the top. The larvae range in color from light green (light phase) (figure below, left) to almost black (dark phase) (figure below, right).

Although there are strong commonalities across global maize growing regions regarding the main ear rot diseases and mycotoxins, there are significant regional variations in disease severity, pathogen species composition (Table 1), mycotoxin occurrence, and manage-ment options.

Crosses of a yellow endosperm variety of maize (California Golden Pop) with a white endosperm variety (Z. Caragua) gave uniformly white progeny in F 1 and a ratio approximating 3 W: I Y in F.

Mar 14, 2025 · Ear rots impact the returns of the crop in two ways: firstly, as a direct yield loss. Ears infected by these diseases may be destroyed, or have significantly lighter kernels, resulting in less tonnage per hectare. The second impact is the financial penalty that may be imposed due to down-grading at the silo.

Aug 9, 2023 · For the morphological traits of ears and kernels, Zhou et al. (2018) identified candidate genes for maize ear length (EL) by combining three mapping strategies; Luo et al. (2022) found that genetic variation in YIGE1 contributed to maize EL and yield.

Color Scale utilized to separate the ears within the same genotype from the Active Maize Germplasm Bank of Embrapa Maize and Sorghum, according to two levels of intensity of color: A (darkest...
