Improving the utilisation of plant genetic resources in resistance
breeding - establishment of a German Network for Cereal Evaluation
H.M. RIEMER 1 and E. SCHLIEPHAKE 2
Abstract
The project aims at a better transfer and spreading of new or unknown resistance
genes into (commercial) breeding programmes to facilitate a more effective use of
genetic resources in cereal resistance breeding. A network of more than 20 private
German plant breeders and research institutes jointly evaluates pre-selected germplasm
of barley and wheat for resistance to the most important fungal and viral
pathogens. Commonly used evaluation methods will be refined to be simultaneously
applicable to several cereal diseases. An information system for an effective acquisition
and provision of the data will be developed by the German Centre for Documentation
and Information in Agriculture (ZADI/IBV). The acquired results will be
shared first of all amongst the project partners for direct use in the respective breeding
programmes and later they will be transferred into BIG (Federal Information System
Genetic Resources). This pilot project commenced in January 2001 and is
funded by the Federal Ministry of Consumer Protection, Food and Agriculture
(BMVEL).
Material and methods
Sets consisting of up to 100 genotypes are selected for both crops (wheat, barley),
and for both spring and winter forms. The material is chosen based on promising results
from previous disease evaluations. Databases from gene banks and research
institutions are used as well as variety lists and relevant publications. The sets consist
of actual breeding material mainly from BAZ Institutes, as well as foreign varieties
and gene bank material.
