QTL mapping in three tropical maize populations reveals a set of constitutive and adaptive genomic regions for drought tolerance
(Springer, 2012)
Despite numerous published reports of quantitative trait loci (QTL) for drought-related traits, practical applications of such QTL in maize improvement are scarce. Identifying QTL of sizeable effects that express more or ...

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 ...

Testcross performance of doubled haploid maize lines derived from tropical adapted backcross populations
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2011)
Doubled haploid (DH) lines produced by in vivo induction of maternal haploids are routinely used in maize breeding. The present study was carried out to assess the performance of 75 doubled haploid maize testcrosses and ...

Morpho-physiological traits associated with cold stress tolerance in tropical maize (Zea mays L.)
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2010)
Winter season maize (Zea mays L.) has emerged a new crop in many parts of South and Southeast Asia, where the crop has to face low temperature regimes (<5°C) for few weeks during vegetative growth stage. The objective of ...

Genetic analysis of water-logging tolerance in tropical maize (Zea Mays L.)
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2010)
Approximately 80% of maize (Zea mays L.) in South and Southeast Asia is grown as a rain-fed crop, where temporary excessive soil moisture or water-logging during the summer-rainy season is one of the major production ...

QTLs asociados al contenido de carotenos en hojas de maiz (Zea mays L.)
(Colegio de Postgraduados, 2012)
Los carotenos son pigmentos antioxidantes que captan foto¬nes del espectro de luz visible y protegen a los tejidos de las plantas contra la foto-oxidación, lo cual está relacionado con la tasa fotosintética y rendimiento ...

Metodo economico y eficiente para la cuantificacion colorimetrica de lisina en grano de maiz
(Sociedad Mexicana de Fitogenética, 2011)
Los maíces (Zea Mays L.) de alta calidad proteínica (ACP) tienen mayor contenido de lisina y triptófano, dos aminoácidos esenciales que normalmente están presentes en bajas cantidades en el grano de maíz. La metodología ...

Effectiveness of Genomic Prediction of Maize Hybrid Performance in Different Breeding Populations and Environments
(Genetics Society of America, 2012)
Genomic prediction is expected to considerably increase genetic gains by increasing selection intensity and accelerating the breeding cycle. In this study, marker effects estimated in 255 diverse maize (Zea mays L.) hybrids ...
