Use of hyperspectral image data outperforms vegetation indices in prediction of maize yield
(Crop Science Society of America (CSSA), 2017)
Hyperspectral cameras can provide reflectance data at hundreds of wavelengths. This information can be used to derive vegetation indices (VIs) that are correlated with agronomic and physiological traits. However, the data ...

Unmanned aerial platform‑based multi‑spectral imaging for field phenotyping of maize
(BioMed Central, 2015)
Background: Recent developments in unmanned aerial platforms (UAP) have provided research opportunities in assessing land allocation and crop physiological traits, including response to abiotic and biotic stresses. UAP-based ...

Testcross performance of doubled haploid maize lines derived from tropical adapted backcross populations
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2011)
Doubled haploid (DH) lines produced by in vivo induction of maternal haploids are routinely used in maize breeding. The present study was carried out to assess the performance of 75 doubled haploid maize testcrosses and ...

Estimation of physiological genomic estimated breeding values (PGEBV) combining full hyperspectral and marker data across environments for grain yield under combined heat and drought stress in tropical maize (Zea mays L.)
(Public Library of Science, 2019)
High throughput phenotyping technologies are lagging behind modern marker technology impairing the use of secondary traits to increase genetic gains in plant breeding. We aimed to assess whether the combined use of ...

Molecular characterization of diverse CIMMYT maize inbred lines from eastern and southern Africa using single nucleotide polymorphic markers
(BioMed Central, 2012)
Background: Knowledge of germplasm diversity and relationships among elite breeding materials is fundamentally important in crop improvement. We genotyped 450 maize inbred lines developed and/or widely used by CIMMYT ...

Enhancing introgression of the Opaque-2 trait into elite maize lines using simple sequence repeats
(African Crop Science Society, 2005)
To improve on the efficiency of Quality Protein Maize (QPM) breeding in Uganada, the utility of three simple sequence repeats (SSR) markers (phi057, phi112 and umc1066) in selection and introgression of the opaque-2 (o2) ...
Article
Quality of field collected and laboratory reared Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) for screening maize genotypes
(Academic Journals, 2013)
The quality of laboratory reared stem borer species for screening of maize varieties is usually questioned by end user cereal breeders. A quality check study was performed in a screen house at KARI-Katumani to evaluate the ...

Impact of adoption of drought-tolerant maize varieties on total maize production in south Eastern Zimbabwe
(Taylor & Francis, 2019)
Drought is a huge limiting factor in maize production, mainly in the rain-fed agriculture of sub-Saharan Africa. In response to this threat, drought-tolerant (DT) maize varieties have been developed with an aim to ensure ...
Article
Major biotic maize production stresses in Ethiopia and their management through host resistance
(Academic Journals, 2018)
Biotic stresses are recently evolving very rapidly and posing significant yield losses of maize production in Ethiopia. A number of high yielding maize hybrids, initially developed as tolerant/resistant, have been taken ...

Evaluación de híbridos experimentales de maíz del PRM en Centro América
(Universidad de Costa Rica, 2003)
El ensayo de híbridos experimentales blancos del PRM-2001, fue evaluado durante el año 2001 en 14 localidades de Centroamérica. El objetivo de este trabajo fue evaluar el rendimiento de grano y características agronómicas ...
