Lettuce (Lactuca sativa) plants exhibiting resistance to downy mildew disease caused by Bremia lactucae are provided, together with methods of producing, identifying, or selecting plants or germplasm with a downy mildew resistance phenotype. Such plants include lettuce plants comprising introgressed genomic regions conferring pest resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed loci, are further provided.

The present disclosure is in the field of plant breeding and disease resistance. A method for the development of a corn plant enhanced for resistance to Colletotrichum graminicola and secondarily to Fusarium spp., both of which incite stalk rot disease, is provided. Also provided is a method to identify corn plants with polynucleotide sequences identified to serve as diagnostic markers for resistance to these pathogens. Further described is the introgression of desired genetic material from one or more parent plants into progeny with precision and accuracy to increase their resistance to these diseases with minimal linkage drag from the donor genome.

The present disclosure provides methods of producing strawberry plants with resistance to Fusarium wilt; and, the strawberry plants, and parts thereof, produced using such methods.

The present invention is in the field of plant breeding and disease resistance. More specifically, the invention includes a method for breeding corn plants containing one or more markers that are associated with resistance to fungi. The invention further includes germplasm and the use of germplasm containing at least one marker associated with resistance to Fusarium stalk rot (FSR) infection for introgression into elite germplasm in a breeding program, thus producing novel FSR resistant germplasm.

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.

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.

The present invention relates to methods and compositions for identifying, selecting and/or producing a Disease resistant soybean plant or germplasm using genes derived from Glycine canescens, Glycine clandestina, Glycine tomentella. A soybean plant or germplasm that has been identified, selected and/or produced by any of the methods of the present invention is also provided. Disease resistant soybean seeds, plants and germplasms are also provided.

An interspecific Dianthus plant is provided. The interspecific plant comprises a genomic sequence distinctive of D. japonicus and a genomic sequence distinctive of Dianthus species not being D. japonicus, the plant exhibiting resistance to Fusarium oxysporum f.sp. dianthi, race 2 which is higher than that of the Dianthus species.

The present invention provides to a novel powdery mildew resistance marker for winter squash plants, a powdery mildew resistant winter squash plant, and a method for producing a powdery mildew resistant winter squash plant using the same. The powdery mildew resistance marker for winter squash plants according to the present invention is characterized in that it includes a powdery mildew resistance locus on chromosome 3.

A Yr4DS gene of Aegilops tauschii and its use thereof in stripe rust resistance breeding of Triticeae plants. Said gene has a sequence as shown in SEQ ID NO. 1, SEQ ID NO. 3, SEQ ID NO. 5, SEQ ID NO. 7, SEQ ID NO. 9, or SEQ ID NO.10.
