Maize hybrids expressing the Cry1F toxin provide efficient control of lepidopteran pests. The Mediterranean corn borer, Sesamia nonagrioides (Lefèvre), is one of the most damaging pests of maize in the Mediterranean basin. In this work we firstly determined the efficacy of maize hybrids expressing the Cry1F toxin (event TC1507) to control neonates of S. nonagrioides. Leaf tissue feeding bioassa...

Combining experimental studies on grain yield variability with crop model simulations in maize could assist choosing the optimum maturity group for a certain location, counteracting effect of climate change. However, considering specificities Southeast Europe are lacking. The objectives were to put various environmental covariates including stress degree days (SDD) into FAO settings determine i...

The present study provides an assessment of the compositional diversity in maize B73 hybrids derived both from the Nested Association Mapping (NAM) founder lines and from a diverse collection of landrace accessions from North and South America. The NAM founders represent a key population of publicly available lines that are used extensively in the maize community to investigate the genetic basi...

A corroborative study was conducted on the maize quality properties of test weight, pycnometer density, tangential abrasive dehulling device (TADD), time-to-grind on the Stenvert hardness tester (SHT), 100-kernel weight, kernel size distribution, and proximate composition as well as maize dry- and wet-millability by six participating laboratories. Suggested operating procedures were given to co...

farmers’ fields, it is not clear that breeders have been successful in achieving greater yield potential as defined This paper addresses the question of whether there has been an by Evans (1993), which is the yield of a cultivar when increase in yield potential of maize (Zea mays L.) hybrids released in the north-central United States since the advent of the “Green grown in environments to whic...

Consequences of drought stress in crop production systems are perhaps more deleterious than other abiotic stresses under changing climatic scenarios. Regulations of physio-biochemical responses of plants under drought stress can be used as markers for drought stress tolerance in selection and breeding. The present study was conducted to appraise the performance of three different maize hybrids ...
