The present invention includes broccoli plants with curds having detached florets and methods for obtaining such broccoli plants. The present invention also provides reagents that can be used in methods for obtaining such broccoli plants.

Purple baby broccoli plants and methods for producing purple baby broccoli plants are disclosed. The invention relates to the plants and seeds of purple baby broccoli and to methods for producing a Brassica oleracea plant having purple head and purple stems plant by crossing the purple baby broccoli with itself or another cultivar. The invention further relates to the parents of purple baby broccoli and for methods of producing purple baby broccoli. The invention also relates to methods for producing locus conversion plants of purple baby broccoli and its parent plants and to the plants produced by those methods. This invention also relates to Brassica oleracea cultivars or breeding cultivars and plant parts derived from purple baby broccoli, to methods for producing other Brassica oleracea cultivars, lines or plant parts derived from purple baby broccoli and to the Brassica oleracea plants, varieties, and their parts derived from the use of those methods.

The present invention relates to a mutant Brassica plant, which is resistant to a pathogen of viral, bacterial, fungal or oomycete origin. The mutant Brassica plant has a reduced level, reduced activity or complete absence of DMR6-1 protein and DMR6-2 protein as compared to a wild type Brassica plant.

The present application discloses a cabbage having resistance against downy mildew or its progeny. The present application further discloses a method for breeding downy mildew resistant cabbage, including introducing downy mildew resistance from a Brassica oleracea plant having resistance against downy mildew into desired cabbage. One embodiment of the present invention provides a novel cabbage line showing high resistance against downy mildew and having a high commercial value as cabbage, and enables breeding such cabbage.

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.

The present disclosure provides Brassica oleracea plants having curds or heads exhibiting increased resistance to downy mildew. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Brassica oleracea MYCOCLP. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.

The present specification discloses a method for detecting an aneuploid of a Brassica oleracea plant, including: performing real-time PCR using DNA extracted from a sample derived from a Brassica oleracea plant to be tested as a template and DNA markers specific to each of two or more chromosomes of Brassica oleracea plant; and detecting chromosomal aneuploidy from a relative difference in amplification amount between the obtained DNA markers. According to one embodiment of the present invention, it is possible to simply, accurately, and rapidly detect an off-type (chromosomal aneuploid) that may occur in Brassica oleracea varieties, in a laboratory equipped with a general molecular biological equipment in the course of seed quality control and breeding research.

The invention provides seeds and plants of broccoli hybrid SVBL0308. The invention thus relates to the plants, seeds and tissue cultures of broccoli hybrid SVBL0308 and to methods for producing a broccoli plant produced by crossing such plants with themselves or with another plant, such as a broccoli plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to plants, seeds, and tissue cultures of broccoli hybrid SVBL0308 comprising introduced beneficial or desirable traits.

Provided herein are Brassica oleracea plants being resistant to the plant pathogen Albugo candida and wherein the resistance is encoded by one genomic region on chromosome. Also provided herein are methods for identifying the present Albugo candida resistance and to molecular markers for use in the present methods.

The invention provides compositions and methods relating to the elevation of glucoraphanin compared to standard Brassica oleracea varieties. The invention also relates to the production of hybrid varieties having desired glucosinolate contents. The invention further provides plants, plant parts, and seeds comprising such traits and comprising a Myb28 allele from Brassica villosa that is not genetically linked to an ELONG allele from Brassica villosa.
