The present invention is directed to watermelon plant and seed, namely of C. lanatus, which are resistant to geminiviruses, especially to begomoviruses including WmCSV, comprising in their genome introgressed sequences from C. colocynthis conferring resistance to said viruses, when present homozygously. The introgressed sequences are preferably characterized by defined alleles of SNPs on chromosome 6. The introgressed sequences can be chosen from those present in the genome of a plant of Citrullus lanatusWMCSVR accession number NCIMB 42197. The invention is also directed to parts of these resistant plants, as well as progeny, to the use of these plants for introgressing the resistance in another genetic background, as well as to different methods for obtaining resistant watermelon plants or seeds.

A novel inbred tetraploid watermelon line designated W087YR is disclosed. The disclosure relates to the seeds of watermelon line designated W087YR, to the plants and plant parts of watermelon line designated W087YR, and to methods for producing a watermelon plant by crossing the watermelon line W087YR with itself or another watermelon plant. Further provided are methods of producing triploid watermelon seed and plants and seedless watermelon fruit produced therefrom as well as the triploid watermelon seed and plants and the seedless fruits produced by such methods.

The present disclosure provides for unique watermelon plants with a desired seed size phenotype and their progeny. Such plants may comprise an introgressed QTL associated with a desired seed size phenotype. In certain aspects, compositions, including distinct polymorphic molecular markers, and methods for producing, breeding, identifying, selecting, and the like of plants or germplasm with a desired seed size phenotype are provided.

The disclosure provides methods for selecting watermelon plants for genetic elements on chromosome 2 and 6 which genetic elements predict the average seed size produced in the fruits of said plants and watermelon plants and plant parts comprising modifications in the tomato-seed size gene (Ts-gene) on chromosome 2, and methods of producing seeds and plants.

A new and distinct watermelon variety NUN 32202 WMW is disclosed as well as seeds and plants and fruits thereof.

A new and distinct watermelon variety NUN 31706 WMW is disclosed as well as seeds and plants and fruits thereof.

A new and distinct watermelon variety NUN 32206 WMW is disclosed as well as seeds and plants and fruits thereof.

A new and distinct watermelon variety NUN 32203 WMW is disclosed as well as seeds and plants and fruits thereof.

A new watermelon variety designated E26C.00181 (Big Jack) is described.

The present invention relates to a modified gene that provides resistance to Cucurbit Yellow Stunting Disorder virus (CYSDV) when present in a plant of the Cucurbitaceae family. The invention further relates to progeny, seed, and fruit of the plant that is resistant against CYSDV. The invention also relates to propagation material suitable for producing the plant that is resistant to CYSDV. Additionally, the invention relates to methods for producing, identifying, and selecting a plant of the Cucurbitaceae family having resistance against CYSDV.
