Genetics of leaf rust resistance in brambling wheat
(American Phytopathological Society (APS), 2008)
The CIMMYT-developed spring wheat ‘Brambling’ has a high level of adult-plant resistance (APR) to leaf rust caused by Puccinia triticina. Our objectives were to determine the genetic basis of resistance in ...

Genetic diversity of African maize inbred lines revealed by SSR markers
(BioMed Central, 2007)
Knowledge of genetic diversity (GD) and relationships among maize inbred lines is indispensable in a breeding program. Our objectives were to (1) investigate the level of genetic diversity among maize inbred lines and (2) ...

Resistance of four inbred maize lines to inoculation with 20 isolates of maize streak virus from Zimbabwe
(American Phytopathological Society (APS), 2006)
Maize streak is the most widespread and important disease of maize in sub-Saharan Africa. Maize streak virus (MSV)-resistant maize germ plasm is available in several countries, but little is known about the stability of ...

Combining ability and heterotic grouping of highland transition maize inbred lines
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2009)
The objectives of the present study were to examine combining ability of highland transition maize inbred lines for grain yield and other desirable traits, to determine heterotic groups of germplasm of the inbred lines and ...

Relative importance of general combining ability and specific combining ability among tropical maize (Zea mays L.) inbreds under contrasting nitrogen environments
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2008)
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) ...

Genetic analysis of partial resistance to powdery mildew in bread wheat line Saar
(American Phytopathological Society (APS), 2006)
Powdery mildew, caused by Blumeria graminis (syn. Erysiphe graminis) f. sp. tritici, is an important disease of bread wheat (Triticum aestivum) in many countries. The CIMMYT bread wheat line Saar has exhibited a high level ...

Relationship between line per se and cross performance under low nitrogen fertility in tropical maize (Zea mays L.)
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2003)
Improved maize yields under low nitrogen (N) fertility is desired for both low- input production systems and also for judicious application of fertilizer nitrogen for a sustainable and environment friendly production ...
