Adoption of maize production technologies in Northern Tanzania
(SADC; CIMMYT; SACCAR, 1998)
The impact of maize research and extension in Tanzania's Northern Zone during the past 20 years was evaluated through a formal survey in 1995. Data were grouped into two major agroecological zones: the intermediate and the ...
A regional analysis of maize biological diversity in Southeastern Guanajuato, Mexico
Four environments with contrasting potential for agricultural productivity and infrastructure development were identified in Guanajuato State, Mexico, to test hypotheses about the relationship of maize biological diversity ...
Determinants of fertilizer and manure use for maize production in Kiambu District, Kenya
(CIMMYT; KARI, 2001)
Farms in Kiambu District are very small owing to high population pressure and need to be intensively farmed to provide enough food for consumption and sale. Since soil nitrogen levels are low, the use of inorganic fertilizers ...
Genomic dissection of leaf angle in maize (Zea mays L.) using a four-way cross mapping population
(Public Library of Science, 2015)
Increasing grain yield by the selection for optimal plant architecture has been the key focus in modern maize breeding. As a result, leaf angle, an important determinant of plant architecture, has been significantly improved ...
Near-Infrared Reflectance Spectroscopy (NIRS) for Protein, Tryptophan, and Lysine Evaluation in Quality Protein Maize (QPM) Breeding Programs
Quality protein maize (QPM) has approximately twice the tryptophan (Trp) and lysine (Lys) concentrations in protein compared to normal maize. Because several genetic systems control the protein quality of QPM, it is essential ...
Minor effects of two elicitors of insect and pathogen resistance on volatile emissions and parasitism of Spodoptera frugiperda in Mexican maize fields
Synthetic elicitors can be used to induce resistance in plants against pathogens and arthropod herbivores. Such compounds may also change the emission of herbivore-induced plant volatiles, which serve as important cues for ...
El potencial de la labranza de conservación en la mixteca Oaxaqueña
(INIFAP; CIMMYT, 1993)
Se llevó a cabo en marzo de 1992 un sondeo en la Mixteca Oaxaqueña, región donde existen problemas fuertes de erosión y sequía que reducen severamente los rendimientos de maíz y de trigo. Dado que las tecnologías de la ...
Genetic interrelationships among medium to late maturing tropical maize inbred lines using selected SSR markers
Understanding the genetic relationships among breeding lines is fundamental in crop improvement programs. The objectives of this study were to apply selected polymorphic single sequence repeat (SSR) DNA markers and cluster ...
