The present disclosure provides Brassica oleracea plants exhibiting broad spectrum resistance to Xanthomonas campestris pv. campestris. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Brassica oleracea var. capitata. 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 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.

One embodiment relates to seed and plants of inbred broccoli line BG-3. Another embodiment relates to the plants, seeds and tissue cultures of inbred broccoli line BG-3, and to methods for producing a broccoli plant produced by crossing such plants with themselves, with another broccoli plant, such as a plant of another genotype, or with vegetatively propagating said plant. Another embodiment further relates to seeds and plants produced by such crossing. Further embodiments relate to parts of such plants, including the fruit and gametes of such plants.

The present invention relates to Brassica oleracea plants resistant to the plant pest diamondback moth Plutella xylostella and, additionally, tolerant to the plant pathogen Xanthomonas campestris pv. campestris. The present invention further relates to methods for identifying the present plants and nucleic acid sequences allowing characterizing, or identifying, the present plants. Specifically, the present invention relates to Brassica oleracea plants resistant to the diamondback moth Plutella xylostella and the plant pathogen Xanthomonas campestris campestris, wherein said resistance to the diamondback moth Plutella xylostella and said tolerance to the plant pathogen Xanthomonas campestris campestris are obtainable from a Brassica oleracea plant deposited under deposit number NCIMB 43822.

The present invention relates to a Brassica oleracea var. italica seed designated 25-BO239 RZ. The present invention also relates to a Brassica oleracea var. italica plant produced by growing the 25-BO239 RZ seed. The invention further relates to methods for producing the broccoli cultivar, represented by broccoli variety 25-BO239 RZ.

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.

Provided herein is an anthocyanin-free broccoli plant including a combination of an inactive MYB2 gene and an inactive DFR1 gene. The present invention further relates to methods for providing the present anthocyanin-free broccoli plants. The present invention also relates to seeds and plant parts of the present anthocyanin-free broccoli plants.

The present invention relates to resistance to Xanthomonas campestris 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.

A method for breeding new purple-orange Chinese cabbage germplasm crosses the purple head Chinese cabbage inbred line 11S96 as the male parent and the orange Chinese cabbage inbred line 11J11 as the female parent. On the basis of selecting individual plants with good heading property in the F.sub.2 population, molecular markers are used to select individual plants carrying the purple-head gene and the orange gene. Through selfing of individual plants for three consecutive generations, a new Chinese cabbage germplasm with green outer leaves and purple-orange head leaves is bred. This method aggregates the purple-head gene and orange gene which are expressed in the head leaves of Chinese cabbage, creating a new Chinese cabbage germplasm with purple-orange head leaves. It enriches Chinese cabbage breeding materials, lays the foundation for breeding the new purple-orange Chinese cabbage variety, and sets a precedent for the aggregation of the head color traits of Chinese cabbage.

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.
