<i>Plasmodiophora brassicae</i>-resistant <i>Brassica </i>plant, seeds and plant parts thereof and methods for obtaining the same

摘要

The present invention relates to a Plasmodiophora brassicae-resistant Brassica plant. The present invention relates more specifically to a Plasmodiophorabrassicae-resistant Brassica plant comprising in its genome two or more genetic factors imparting resistance, where in the presence of the genetic factors imparting resistance can be determined by the presence of a Quantitative Trait Locus (QTL1) and a Quantitative Trait Locus (QTL3) and/or a Quantitative Trait Locus 5 (QTL5).

1. A Plasmodiophora brassicae-resistant hybrid Brassica oleracea plant comprising in its genome three or more genetic factors imparting resistance, wherein the Plasmodiophora brassicae-resistance is from a plant with deposit number NCIMB 41685; wherein the genome includes a Quantitative Trait Locus 1 (QTL1) and a Quantitative Trait Locus 3 (QTL3) and a Quantitative Trait Locus 5 (QTL5),
wherein QTL1 is characterized by a Random Amplified Microsatellite Polymorphism (RAMP) marker comprising a fragment of 294 bp with primer combination SEQ ID NOs:1 and 7; QTL3 is characterized by a RAMP marker comprising a fragment of 159 bp with primer combination SEQ ID NOs:9 and 7; and QTL5 is characterized by a RAMP marker comprising a fragment of 276 bp with primer combination SEQ ID NOs:16 and 7.
