Physical and sensory properties of biofortified fresh yellow maize: varietal and harvesting time effects on physical and sensory properties of biofortified fresh yellow maize por Alamu, O.E., Maziya-Dixon, B.B., Olaofe, O.

“…Freshly harvested eight biofortified yellow maize hybrids and eight open pollinated varieties (OPV) with various endosperm textures were used for this research. Selected fresh harvested yellow maize ears at three maturity stages (20, 27 and 34 days after pollination) were boiled and roasted with or without husk and sensory evaluation was carried out on the boiled and roasted fresh yellow maize samples. …”

Crop management affects dry-milling quality of flint maize kernels por Cirilo, Alfredo Gabriel, Actis, Marcos, Andrade, Fernando Hector, Valentinuz, Oscar Rodolfo

“…The flint type is harder than the dent and semi-dent maize, yielding a higher proportion of big endosperm pieces in the mill. Nevertheless, crop growing conditions could modify milling properties. …”

Expression of internal reproductive barriers in a germplasm bank accession of the wild potato Solanum chacoense Bitter in three ex situ regeneration cycles por Poulsen Hornum, Anabela, Camadro, Elsa Lucila

“…To ascertain if Ne = N in seed regeneration of one randomly provided accession of S. chacoense Bitter, pollen viability and size, plus pollen-pistil relationships and number and type (according to endosperm development) of seeds/fruit were studied, respectively, at the individual plant and genotypic combination levels. …”

Kernel hardness-related traits in response to heat stress during the grain-filling period of maize crops por Mayer, Luis Ignacio, Cirilo, Alfredo Gabriel, Maddonni, Gustavo Angel

“…The impact of early and late postflowering heat stress on kernel physical traits related to hardness was studied on field-grown maize hybrids differing in their prevailing endosperm texture (two hybrids with a vitreous texture, and two others with a floury texture). …”

Host plant resistance to infestation of Fall armyworm, Spodoptera frugiperda (J. E. Smith), in tropical maize, (Zea mays L.), germplasm por Udah, O.

“…Early and extra-early maturing lines were divided into eleven groups based on maturity and endosperm color. Artificial infestation with FAW larvae was carried out two weeks after planting, with an average of four larvae per plant stand. …”

Kernel number and kernel weight determination in dent and popcorn maize por Severini, Alan David, Borrás, Lucas, Westgate, Mark E., Cirilo, Alfredo Gabriel

“…Maize popcorn genotypes have been studied less extensively, but their kernels are known to differ in terms of endosperm structure and typical growth patterns. Our objective was to evaluate how variation in plant growth rate (PGR) at different stages of kernel formation and development affected kernel number per plant (KNP), individual kernel weight (KW) and rate and duration of kernel growth in popcorn genotypes, relative to dent ones. …”

Membrane-permeable trehalose 6-phosphate precursor spray increases wheat yields in field trials por Griffiths, Cara A., Xiaochao, Xue, Miret, Javier A., Salvagiotti, Fernando, Acevedo-Siaca, Liana G., Gimeno, Jacinta, Reynolds, Matthew P., Hassall, Kirsty L., Halsey, Kirstie, Puranik, Swati, Oszvald, Maria, Kurup, Smita, Davis, Benjamin G., Paul, Matthew J.

“…Mechanistic analyses reveal that these benefits arise from increased CO2 fixation and linear electron flow (‘source’) as well as from increased starchy endosperm volume, enhanced grain sieve tube development and upregulation of genes for starch, amino acid and protein synthesis (‘sink’). …”

A genetic approach to the species problem in wild potato por Camadro, Elsa Lucila, Erazzu, Luis Ernesto, Maune, Juan Federico, Bedogni, Maria Cecilia

“…In nature, wild potato populations are isolated through external and internal hybridisation barriers; the latter, which are genetically determined, can be either pre‐zygotic (pollen–pistil incompatibility) or post‐zygotic (abortion of embryo, endosperm or both tissues, sterility, and hybrid weakness and breakdown in segregating generations). …”

Morphological and genetic diversity of maize landraces along an altitudinal gradient in the Southern Andes por Rivas, Juan Gabriel, Gutierrez, Ángela Verónica, Defacio, Raquel Alicia, Schimpf, Jorge, Vicario, Ana L., Hopp, Horacio Esteban, Paniego, Norma Beatriz, Lia, Veronica Viviana

“…Assessment of morphological variation in a common garden allowed the discrimination of two groups, which differed mainly in endosperm type and overall plant size. Although the groups retrieved by the molecular analyses were not consistent with morphological clusters, they showed a clear pattern of altitudinal structuring. …”

Genetic analysis of extra-early yellow and orange quality protein maize (Zea mays L.) inbread lines under low nitrogen and Striga stresses por Abu, P.

“…The admixture model-based population structure method and the unweighted pair group method with arithmetic mean (UPGMA) clustering method revealed five clusters among the inbreds based principally on the endosperm colour, pedigree and selection history. Thirty-eight percent of the lines assayed for tryptophan content had levels that met the minimum requirement of 0.07%, indicating the need to introgress tryptophan favourable alleles into the source populations. …”

Nitrogen–sulfur fertilisation effects on gluten composition and industrial quality in Argentinean bread wheat cultivars differing in apparent sulfur recovery por Arata, Agustin Francisco, Rogers, Willian, Tranquilli, Gabriela, Arrigoni, Adriana C., Rondanini, Deborah Paola

“…Genotype has an important role in determining potential grain end-use quality, because it defines the protein subunits stored in the endosperm. Nitrogen (N) and sulfur (S) availability modulate the expression of the genotype by determining variations in quantitative gluten composition. …”

Variation in Thickness of Embryo Covering Structures and Their Role in the Regulation of Seed Physiological Dormancy of Chenopodium hircinum (Amaranthaceae) por Agüero Martínez, Paola Fernanda, Cardozo, Leonardo, Gómez, Carlos A., Lopez Spahr, Diego, Baskin, Carol C., Bertero, Héctor Daniel, Galindez, Guadalupe, Curti, Ramiro Nestor

“…The seed coat was formed by palisade cells impregnated with tannins, and the seed contained a thin layer of peripheral endosperm surrounding the embryo. In our investigation, the thickness of the pericarp (P) and/or seed coat (SC) varied among populations. …”

Expansion of the basic knowledge on the inheritance of characters that allow the development of new maize brreeding techniques = Expansión de los conocimientos básicos de la herenc... por Salerno, Juan Carlos, Kandus, Mariana Virginia, Prada, Arturo, Almorza, David

“…This goal requires an expansion of the basic knowledge of the inheritance of characters in order to develop new breeding techniques to improve experimental materials with hard endosperm (flint). The balanced lethal system allows to study the relative contribution of different chromosome segments to hybrid vigour due to the heterozygosity of certain chromosome segments while the rest of the genome becomes homocygotic through continuous selfing. …”

Dietary fibre composition and sensory analysis of heat treated wheat and rye bran por Johansson, Matilda

“…Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. …”
