Abstract
Introgression of genetic traits from wild apple germplasm (Malus spp.) into commercial apple cultivars is a painstakingly slow process. For e.g. introgression of the Vf gene from Malus floribunda 821 for resistance to apple scab, caused by the fungus Venturia inaequalis, took more than 80 years due to genetic drag and the long juvenile period of apple. In order to speedup the classical breeding, molecular techniques can be applied to enrich existing commercial apple varieties with functional alleles from sexually compatible plants, preventing genetic drag and keeping the genetic makeup of the commercial cultivar. This concept is named “cisgenesis”. This paper describes several approaches and considerations for development of cisgenic apples and stacking of genes. Also we provide an overview of isolated alleles from apple available for cisgenesis at the moment and in the near future
