In one embodiment, of the RDR1 genes in the combination is represented by SEQ ID NO: 1 or has at least 70% sequence identity, and one of the RDR1 genes in the combination is represented by SEQ ID NO: 3 or has at least 70% sequence identity; or one of the RDR1 genes in the combination encodes a protein represented by SEQ ID NO: 2 or a protein that has at least 70% sequence identity, and one of the RDR1 genes encodes a protein represented by SEQ ID NO: 4 or a protein that has at least 70% sequence identity.

The present invention relates to a hybrid between a leek and a garlic plant. More specifically, the invention relates to an interspecific hybrid plants resulting from a cross between an Allium ampeloprasum plant and an Allium sativum plant. Specifically, the present invention relates to Interspecific hybrid plants derived from a cross between an Allium ampeloprasum plant and an Allium sativum plant, wherein the hybrid plants are capable of producing seed and contains nuclear genomic material derived from both said Allium ampeloprasum plant and said Allium sativum plant, and further wherein the interspecific hybrid plants contain at least 250 mg/kg of allicin when determined in the white part of the leaf sheet of the plants and furthermore wherein the interspecific hybrid plants are obtainable, obtained or derived, from an interspecific hybrid plant as deposited under accession number NCIMB 42564.

The present invention relates to novel watermelon plants displaying an increased number of male flowers. The present invention also relates to seeds and parts of said plants, for example fruits. The present invention further relates to methods of making and using such seeds and plants. The present invention also relates to novel genetic determinants associated with an increased number of male flowers and to molecular markers linked to said novel genetic determinants.

The present disclosure is in the field of plant breeding and disease resistance. The disclosure provides methods for breeding corn plants having downy mildew (DM) resistance using marker-assisted selection. The disclosure further provides corn germplasm resistant to DM. The disclosure also provides markers associated with DM resistance loci for introgressing these loci into elite germplasm in a breeding program, thus producing novel DM resistant germplasm.

The present disclosure is in the field of plant breeding and disease resistance. The disclosure provides methods for breeding corn plants having late wilt (LW) resistance using marker-assisted selection. The disclosure further provides corn germplasm resistant to LW. The disclosure also provides markers associated with LW resistance loci for introgressing these loci into elite germplasm in a breeding program, thus producing novel LW resistant germplasm.

A Cucumis sativus var. sativus plant tolerant to Tomato Leaf Curl New Delhi Virus (ToLCNDV) includes in its genome the combination of a first quantitative trait locus (QTL) QTL1 on chromosome 1 and a second QTL, QTL2 on chromosome 2, at least one of QTL1 and QTL2 being homozygous, wherein said combination confers to the plant tolerance to ToLCNDV and said QTLs on chromosomes 1 and 2 are present in the genome of the seeds of plant TOCUR6080, NCIMB accession number 43427. The QTL are preferably characterized by defined alleles of different SNPs on chromosomes 1 and 2. Parts of these plants have ToLCNDV tolerance phenotype, as well as progeny, and can be used for introgressing the tolerance in another genetic background, with different methods for obtaining cucumber plants or seeds with increased tolerance to ToLCNDV and different markers linked to the QTLs used to confer tolerance phenotype.

The present application relates to the technical field of genetic breeding, and provides a method for identifying whether a diploid potato is self-compatible. The method relates to identifying whether a StSCI gene in the diploid potato is transcribed and expressed. Also disclosed is a method for identifying whether a StSCI gene is expressed by using molecular marker, and a method of screening for the molecular marker, which includes: obtaining the genome sequence information of parental materials, screening for difference sites of the parental materials, screening for the molecular marker, and identifying whether the screened molecular marker are usable. As for the identification of the self-compatibility of a diploid potato by using the screened molecular marker, the identification workload is small, a lot of time is saved, and the identification result is not affected by the environment, and it is accurate and reliable.

The invention relates to methods and compositions for identifying and selecting maize plants with enhanced resistance to northern leaf blight. Maize plants generated by the methods of the invention are also a feature of the invention.

The present disclosure provides for unique onion plants with QTLs conferring Fusarium basal rot and pink root resistance and lacking the complementary pinks trait and their progeny. Such plants may comprise an introgressed QTL associated with multiple disease resistance coupled with a desirable bulb color. In certain aspects, compositions, including distinct polymorphic molecular markers, and methods for producing, breeding, identifying, selecting, and the like of plants or germplasm with disease resistance and/or desirable bulb color are provided.

Uses and pea plant cells of pea plants and parts thereof, which contain higher protein than current varieties, are provided. Phenotypic and genotypic analysis of many pea varieties was performed to derive markers for high protein and other phenotypic traits, and a breeding simulation was used to identify the most common and most stable markers. Following verification of trait stability over several generations, markers and marker cassettes were defined as being uniquely present in the developed pea lines. The resulting high protein pea lines can be used to enhance the nutritional values of pea in its various uses. Uses include processing the seeds to yield any of pea protein isolate, pea concentrate, a texturized product, a meat analog and/or commodity whole or split grains.
