Collaborative project: Identification and functional characterisation of the Co (columnar) -gene in columnar apple varieties as a basis for a systematic use in breeding - Subproject 2
Project
Project code: 2814304307
Contract period: 01.04.2009
- 31.12.2012
Budget: 265,507 Euro
Purpose of research: Experimental development
This project aimed at the efficient selection of columnar apple varieties as a basis for a new production system. The columnar growth type is an accidentally discovered natural mutation of a single gene and is inherited in a dominant way. It has the potential for a less laborintensive production and thus is economically of high interest. We could with great certainty identify the genomic variation causing the columnar growth type. A final prove will follow in the near future. This result allows on the one hand side a functional characterization of the genomic variation causing columnar growth and is thus a key for understanding the genetic control of growth habit in apple. Also, the first real 100% marker for the mutation causing columnar growth has been produced allowing a selection at a very early seedling stage. In addition, a basis for identifying possible QTL´s for the tolerance against apple canker (Nectria galligena) has been laid.
