PCR markers of apple resistance against scab (Venturia inaequalis CKE.) controled by Vf gene in Czech apple breeding

Popis výsledku v původním jazyce

The varieties of apples resistant against apple scab (Venturia inaequalis CKE.) are among the latest outcomes of breeding this fruit species not only in the worldwide but also in the Czech Republic. A common donor of resistance against this disease is Malus floribunda Sieb., clone 821, which has conferred the qualitative resistance based on the dominant Vf gene. The object of this article is to characterise the Vf gene in a collections of new apple Czech varieties. There were used published primers forPCR evaluation of the collection of twenty Czech varieties, seventeen varieties of worldwide assortment and six new resistant selections of Czech breeding. All varieties possessing resistance based on Vf gene had heterozygous constitution of Vf gene (Vfvf). Segregated F1 progeny, which was already selected by infection tests in greenhouse, was put the same PCR test through. In all progenies were found also recessive homozygous genotypes (vfvf) that have not been selected out by infection
