| Conservation tillage (no-till and reduced tillage) brings many benefits with respect to soil fertility and energy use, but it also has drawbacks regarding the need for synthetic fertilizers and herbicides. To promote conversation tillage in organic farming systems, crop rotation, fertilization and weed control have to be optimized. In addition, crop varieties are needed with improved nutrient use efficiency (NUE) and high weed competitiveness or tolerance. |

| Organic farming has gained in importance in Germany during recent years.Therefore an increasing demand exists for varieties with specific adaptation to this farming system. In the present study we therefore conducted comparative field experiments with modern maize breeding materials under organic versus conventional farming conditions (ORGandCON, respectively) to estimate quantitative genetic parameters needed for developing optimal breeding strategies and to investigate the perspectives of selection for specific adaptation to ORG. Starting from two broad samples of elite germplasm, consisting of 178 flint and dent lines, respectively, fractions of 11 flint and 11 dent lines were selected based on their testcross performance under ORG. A corresponding set... |

| Organic farming has gained in importance in Germany during the past years. Therefore an increasing demand exists for varieties with specific adaptation to this farming system. Hence it becomes necessary for plant breeders to optimize their selection strategy for varieties which meet the requirements of organic farming. For this purpose a research project was conducted at the University of Hohenheim, Institute of Plant Breeding, Seed Science, and Population Genetics in cooperation with the KWS SAAT AG. It was supported by the “Bundesprogramm Ökologischer Landbau” and lasted from April 2004 to December 2006. In the present contribution the results of comparative trials with maize under organic and conventional farming conditions in 2004 and 2005 are... |
