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 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 ...
