Genetic characterization of a core set of a tropical maize race Tuxpeño for further use in maize improvement
The tropical maize race Tuxpeño is a well-known race of Mexican dent germplasm which has greatly contributed to the development of tropical and subtropical maize gene pools. In order to investigate how it could be exploited ...
Agricultural extension, collective action and innovation systems: Lessons on network brokering from Peru and Mexico
Purpose: New approaches to extension service delivery are needed that stimulate increased agricultural production, contribute to collective action and which also foster the emergence of agricultural innovation systems. ...
QTL for yield and associated traits in the Seri/Babax population grown across several environments in Mexico, in the West Asia, North Africa, and South Asia regions
Heat and drought adaptive quantitative trait loci (QTL) in a spring bread wheat population resulting from the Seri/Babax cross designed to minimize confounding agronomic traits have been identified previously in trials ...
Nitrogen leaching and soil nitrate, and ammonium levels in an irrigated wheat system in northern Mexico
Nitrate leaching from agricultural soils can represent a substantial loss of fertilizer nitrogen (N), but a large variation in losses has been reported. We report N leaching losses under four N fertilizer treatments and ...
CIMMYT's genetic progress in wheat grain quality under four nitrogen rates
Wheat (Triticum aestivum L.) breeders often try to simultaneously improve grain yield and bread-making quality. This study examined changes in CIMMYT's wheat germplasm with respect to grain protein concentration (GPC)- and ...
