The metal silo : An effective grain storage technology for reducing post-harvest insect and pathogen losses in maize while improving smallholder farmers' food security in developing countries
Traditional storage practices in developing countries cannot guarantee protection against major storage pests of staple food crops like maize, leading to 20?30% grain losses, particularly due to post-harvest insect pests ...
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 ...
Genetic distance among doubled haploid maize lines and their testcross performance under drought stress and non-stress conditions
In contrast to conventional inbreeding that takes up to seven generations to develop inbred lines, the doubled haploid (DH) technology allows production of inbred lines in two generations. The objectives of the present ...
Resistance of tropical maize genotypes to the larger grain borer
Post-harvest losses caused by the larger grain borer (LGB, Prostephanus truncatus) aggravate food insecurity among small-scale farmers. Host plant resistance is a method of LGB control which should be prioritized in order ...
Quality control genotyping for assessment of genetic identity and purity in diverse tropical maize inbred lines
Quality control (QC) genotyping is an important component in breeding, but to our knowledge there are not well established protocols for its implementation in practical breeding programs. The objectives of our study were ...
Phenotypic and genotypic variation in tropical maize inbred lines for resistance to the maize weevil and larger grain borer
The maize weevil (Sitophilus zeamais) and larger grain borer (Prostephanus truncatus) are economicallyimportant postharvest insect pests that cause severe losses in stored grain. The use of host-plant resistance is the ...
Resistance of maize varieties to the maize weevil Sitophilus zeamais (Motsch.) (Coleoptera: Curculionidae)
This study aimed at evaluating commonly used maize varieties, collected from Melkasa and Bako Agricultural Research Centers and Haramaya University, Ethiopia, against the maize weevil Sitophilus zeamais Motsch., one of the ...
Resistance of three-way cross experimental maize hybrids to post-harvest insect pests, the larger grain borer (Prostephanus truncatus) and maize weevil (Sitophilus zeamais)
The larger grain borer Prostephanus truncatus Horn and the maize weevil Sitophilus zeamais Motschulsky are important pests of stored maize in the tropics, particularly where maize is stored on-farm with little control of ...
Testcross performance of doubled haploid maize lines derived from tropical adapted backcross populations
(Consiglio per la ricerca in agricoltura e l'analisi dell'economia agraria, Forestry Reaserch Centre; Istituto Sperimentale per la Cerealicoltura, 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 ...
