(Colegio de Postgraduados, 2007)
Gray leaf spot of maize (Zea mays L.), caused by the fungus Cercospora zeae maydis Tehon & Daniels, has become an economically important disease in tropical humid maize growing areas of the Republic of Colombia. To implement ...
Comparison of the performance of synthetic maize varieties created based on either genetic distance or general combining ability of the parents
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2012)
Synthetics varieties are grown by farmers and used by breeders to select new inbred lines. In countries unable to market hybrids, use of synthetics leads to yield improvements over landraces. Synthetics are derived from ...
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) ...
