ABSTRACT Measures of epistasis in maize hybrids have been estimated by (i) triple-test crosses, (ii) making comparisons Certain maize (Zea mays L.) inbred lines are more successful than of single, three-way, and double cross hybrids, or (iii) others in forming elite hybrids. This study was conducted to determine measuring variance components (Hallauer and Miwhether epistatic interactions play a...
Transgenic maize, Zea maize L., expressing the Cry1F protein from Bacillus thuringiensis has been registered for Spodoptera frugiperda ( J. E. Smith) control since 2003. Unexpected damage to Cry1F maize was reported in 2006 in Puerto Rico and Cry1F resistance in S. frugiperdawas documented. The inheritance of Cry1F resistance was characterized in a S. frugiperda resistant strain originating fro...

In order to study the effect of different intercropping combinations on some maize qualitative traits, an experiment was conducted as a completely randomized block design with three replications in Agricultural Research Station, Faculty of Agriculture, University of Tabriz, Iran, in 2006 and 2007. Two maize (Zea mays L.) hybrids (704, 301), vetch (Vicia villosa), bitter vetch (Vicia ervilia), b...

The evolution of resistance and cross-resistance threaten the sustainability of genetically engineered crops that produce insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt). Western corn rootworm, Diabrotica virgifera virgifera LeConte, is a serious pest of maize and has been managed with Bt maize since 2003. We conducted laboratory bioassays with maize hybrids producing...
