Low-N stress is among the major abiotic stresses causing yield reductions in maize grown in the mid-altitude tropical environments of Africa. This study estimates the relative importance of general combining ability (GCA) ...

Elite germplasm and adequate genetic variation are essential in successful plant breeding programs.Maize (Zea mays L.) breeding programs in the U.S. Corn Belt have realized significant genetic advance with a limited sample ...

The utilization of site regression models (SREG) on multilocation testing allow the detection of significant differences in the genotype x environment interaction, even though these may not be detected by the analysis of ...

Testcross evaluation is used to determine the relative potential of corn (Zea mays L.) lines in a hybrid breeding program. Choice of tester is important for efficient selection among lines for their potential in hybrids. ...

Un enfoque central de la investigacion agricola en Mexico ha sido la generacion de variedades mejoradas de maiz (Zea mays L.) de alto rendimiento y su difusion, pese a que los maices criollos siguen desempeñando un papel ...

Mexico is considered the center of origin and domestication of maize (Zea mays L.), and it is recognized as one of the most important centers of diversity. Evaluation of native maize diversity is specially important for ...
