Evaluation of Popcorn Germplasm for Resistance to Sesamia nonagrioides Attack

Revilla Temiño, Pedro ; Butrón Gómez, Ana María ; Sandoya Miranda, Germán ; Malvar Pintos, Rosa Ana ; Ordás Pérez, Amando

Popcorn adapted to Spanish conditions could be an interesting and profitable alternative to field corn. However, little is known about breeding popcorn germplasm for adaptation to Spain. Sesamia nonagrioides Lefèvbre is the main insect pest affecting popcorn quality and yield under Spanish growing c...

Concept for planing conservation schemes for farm animal genetic diversity focussed on German chicken breeds

Pinent, Tamina

Genetic diversity is the base for future breeding in all farm animal species and therefore needs to be conserved. Criteria for the choice of breeds to be included in conservation programs are essential for the design of conservation strategies. In this study, such criteria were developed based on We...

Combining Maize Base Germplasm for Cold Tolerance Breeding

Rodríguez Graña, Víctor Manuel ; Butrón Gómez, Ana María ; Sandoya Miranda, Germán ; Ordás Pérez, Amando

Early planting can contribute to increased grain yield of maize (Zea mays L.), but it requires cold tolerance. A limited number of cold-tolerant maize genotypes have been reported. The objectives of this study were to test a new strategy to improve cold tolerance in maize searching for broad x narro...

Application of Molecular Markers in Sugar Beet Breeding

Hjerdin Panagopoulos, Annika

Around 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. Sugar content is still one of the most important characters...
