  • Patent number: 10750700
    Abstract: Provided herein are sprouting broccoli plants, or Brassica oleracea convar. botrytis var. asparagoides plants, with one or more improved phenotypes such as floret development in a single horizontal plane allowing simultaneous harvest of all florets, a reduced cultivation period until harvest and/or not requiring exposure to a cold period below 15° C. during at least one to two weeks. Also provided herein are seeds, cells and plant parts, especially harvestable plant parts such as florets, of the present plants.
    Type: Grant
    Filed: December 8, 2015
    Date of Patent: August 25, 2020
    Assignee: BEJO ZADEN B.V.

  • Patent number: 9000258
    Abstract: The present invention relates to a Xanthomonas campestris pv. campestris (Xcc) resistant Brassica plant, and seeds, fruits and or plant parts thereof, and to methods for preparation thereof. Specifically, the present invention relates to a Xcc resistant Brassica oleracea plant, and seeds, fruits and/or plant parts thereof, and methods for preparation thereof. Further, the present invention relates to Quantitative Trait Loci (QTL's) providing the present Xcc resistance and molecular markers, specifically Random Amplified Microsatellite Polymorphism (RAMP) markers, for identifying the present QTL's.

  • Patent number: 8445752
    Abstract: At least one embodiment of the present invention relates to Brassica oleracea plants with a resistance gene to Albugo candida, the cause of white blister. At least one embodiment of the invention also relates to a method for providing a Brassica oleracea plant with a resistance to Albugo candida, the at least one embodiment including a) providing a first B. oleracea plant which comprises a resistance gene to A. candida; (b) crossing the resistant plant with a susceptible second B. oleracea plant; (c) isolating genomic DNA from the progeny for detecting the presence of an introgression with the resistance gene using one or more specific DNA markers linked to the resistance gene; and (d) selecting from the progeny a B. oleracea plant in which the presence of the introgression with the resistance gene has been demonstrated in step (c).
