Introduction: The Mediterranean corn borer (MCB), Sesamia nonagrioides, is a major pest of maize, Zea mays, in Mediterranean countries, inflicting significant kernel yield losses. For that reason, it necessary to know the genetic mechanisms that regulate the agronomic and resistance traits. A quantitative trait loci (QTL) mapping study for yield, resistance against MCB attack, and other relevan...

The objective of this study was to evaluate genetic variability and select putative mutants of Terra Maranhão plantain cultivar (AAB genome) subjected to gamma radiation based on agronomic data and inter simple sequence repeat molecular marker profiles using the Ward-MLM strategy. A total of 233 irradiated plants and 41 controls were assessed. The agronomic and molecular data were subjected to ...

Currently, only few glufosinate-resistant genes are available for commercial application. Thus, developing novel glufosinate-resistant genes with commercial feasibility is extremely important and urgent for agricultural production. In this study, we transferred a newly isolated RePAT gene into a japonica rice variety Zhonghua11, resulting in a large number of independent T0 transgenic plants, m...

Defining selection criteria is important to obtain promising genotypes in a breeding program. The objective of this study was to estimate genetic parameters for agronomic traits and to perform soybean line selection using selection indices. The experiment was conducted at an experimental area located at Capim Branco farm, belonging to the Federal University of Uberlândia. A total of 37 soybean ...

soil compaction has become a widespread problem in the world and is one of the factors involved in land degradation and declining crop yields, especially in the arid and semi-arid agriculture. the purpose of this study was to investigate the effects of subsoil compaction on morphological, physiological and agronomic aspects of wheat .the research was carried out in the experimental farms of anb...

some substitution lines between two parental lines for complex traits allows for the identification of single Genetic analyses of complex traits in wheat (Triticum aestivum L.) chromosomes containing QTLs for those traits (Berke are facilitated by the availability of unique genetic tools such as chroet al., 1992a,b; Cantrell and Joppa, 1991). Single recipromosome substitution lines and recombin...
