The present invention includes cauliflowers with enhanced whiteness and methods for obtaining such cauliflowers. The present invention also provides reagents that can be used in methods for obtaining such cauliflowers.

The present invention relates to resistance to Xanthomonascampestris pv. campestris (Xcc) in cauliflower. According to the invention, the resistance is provided by DNA sequences, introgressed from a green cauliflower at specific loci in the genome of a white cauliflower. The introgressed sequences can be present homozygously or heterozygously in the genome of the white cauliflower, and they confer resistance to Xcc. The invention further relates to part of these cauliflowers, to seeds, to the progeny of these cauliflowers, and to method for producing cauliflowers resistant to Xcc.

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.

This invention provides a Brassica oleracea plant with high S-methylmethionine content. This invention relates to a Brassica oleracea plant with higher S-methylmethionine content than that in a conventional Brassica oleracea plant. Specifically, this invention relates to a Brassica oleracea plant with the S-methylmethionine content of 48 mg/100 g fresh weight or more.

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.

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.

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 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.

A Brassica oleracea plant is provided having self-compatibility, or a progeny thereof, wherein the plant excludes cauliflower and Chinese kale. For example, a Brassica oleracea plant having self-compatibility is provided. Thereby, technical means that makes it possible to accomplish stable and efficient production of parental line seeds for a Brassica oleracea plant can be provided.

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.
