Maize (corn) is one of the most widely grown cereal crops globally. Fungal diseases of maize cause significant economic damage by reducing maize yields and by increasing input costs for disease management. The most sustainable control of maize diseases is through the release and planting of maize cultivars with durable disease resistance. The wheat gene Lr34 provides durable and partial field r...

This study's primary objective was to assess the quality parameters of fifteen different genotypes Serbian maize hybrids in order establish whether they were suitable for making high-quality silage ruminant feed. The study carried out as a two-year field experiment at Maize Research Institute Zemun Polje, Serbia. Laboratory analyses included yield structure examined hybrids, evaluation composit...

In maize (Zea mays L., 2n = 2x = 20), map-based cloning and genome organization studies are often complicated because of the complexity of the genome. Maize chromosome addition lines of hexaploid cultivated oat (Avena sativa L., 2n = 6x = 42), where maize chromosomes can be individually manipulated, represent unique materials for maize genome analysis. Maize chromosome addition lines are partic...

to determine the yield stability, adaptability and analysis of the genotype× environment interaction of virginia tobacco, 15 hybrids of tobacco including 10 iranian and 5 international hybrids were evaluated in two different experiments (water stress and normal irrigation) using a randomized complete block design (rcbd) with three replications at two locations including rasht and tirtash tobacc...

The use of transgenic Bt maize hybrids continues to increase significantly across the Corn Belt of the United States. In 2009, 59% of all maize planted in Illinois was characterized as a "stacked" gene variety. This is a 40% increase since 2006. Stacked hybrids typically express one Cry protein for corn rootworm control and one Cry protein for control of several lepidopteran pests; they also fe...

Here, we analyzed whether the microRNA (miRNA) expression levels differ between maize inbred lines B73 and Mo17 and their reciprocal hybrids under salt and drought stress. We found that miR156, miR164, miR166, miR168, miR171 and miR319 are differentially expressed under abiotic stress. Interestingly, Mo17 × B73 showed the strongest change in miRNA expression in response to salt or drought stres...

in order to evaluate the effect of nitrogen absorption and use efficiency in relay intercropping for winter wheat and maize, a field experiment was conducted during 2008-2009 at the agricultural research station of ferdowsi university of mashhad, iran. a randomized block design with three replications was used. treatments included four combinations of relay intercropping of wheat and maize (thr...

Corn smut fungus (Ustilago maydis [DC.] Corda) is a globally widespread pathogen affecting both forage and sweet maize hybrids, with higher significance in maize. Remote sensing technologies demonstrated favorable results for disease monitoring on the field scale. The study focused changes vegetation index (VI) values influenced by pathogen. In this study, four two hybrids were examined. Artifi...
