A new Helianthus plant named SUR67-1 particularly distinguished by the medium to large size yellow decorative inflorescences, vigorous size plant, round mound plant habit, with a natural flowering response of early May until late September.

A breeding method for rapidly stabilizing cotton distant hybridization progeny is disclosed. It belongs to the technical field of plant breeding. The disclosure is based on VSG (G. barbadense semi-compatible material) as female parent, general G. hirsutum materials as male parent of the cross to get F1 generation of G. barbadense-G. hirsutum hybrid materials, and treats the F1 generation of young bolls with 0.03-0.05% of colchicine aqueous solution to induce F2 generation to separate the stable intermediate materials or new varieties with excellent genes of both G. barbadense and G. hirsutum, so as to produce new cotton germplasm resources. The main innovation of the present disclosure lies in that it changes the previous treatment position and method of colchicine on cotton plant, and the disclosure is not limited by haploid and directly treats the cotton bolls on F1 cotton plants.

The present invention provides a novel method for producing the rice haploid, i.e., producing the rice haploid by ricemaize hybridization. In this method, rice is used as the female parent, and the rice panicle is emasculated and then pollinated with fresh maize pollens; the emasculated panicle is sprayed with 2, 4-D solution at 50-200 mg/L 24 h after pollination, and after 15-20 days the rice panicle is cut off to collect caryopses; and the haploid embryos are obtained by dissectting caryopses asepticlly, then inoculated and cultured with MS medium, then the haploid embryos directly germinate into rice haploid seedlings. Compared with the existing main methods for producing the rice haploid, such as anther culture and isolated microspore culture, the rice haploid production method of the present invention reduces the dependence on rice genotypes, does not produce mixture of haploid and diploid plants, contains no albino seedling, and is simpler in technical operation.

The present invention relates to cultivated cucumber plants comprising a yield QTL on chromosome 2 and/or chromosome 6 of their genome.

The present invention relates to cultivated cucumber plants comprising a yield QTL on chromosome 2 of their genome.

A Brassicaceae plant containing a large amount of glucoraphanin is obtained. A first parent plant and a second parent plant, which are both Brassicaceae plants classified into different genera, are crossbred, thereby obtaining an intergeneric crossbred plant. The first parent plant has 5 mg/100 g (fresh weight) or more of glucoraphanin. The second parent plant has a loss-of-function type glucoraphasatin synthase gene.

The present invention provides tomato plants exhibiting resistance to TOSPO (GBNV) Virus exhibiting the traits of healthy and evenly ripened fruits without brown spots, reduced wilting of the top portion of the tomato plants and reduced dark spots on the leaves and stems of the tomato plant, and materials useful for improving tomato yield. In particular, the present invention provides a path to development of hybrid tomato plants exhibiting resistance to TOSPO virus infection, seed of hybrid tomato plants exhibiting TOSPO virus resistance, and methods of producing the same. Methods described herein involve the use of marker assisted selection and marker assisted backcrossing utilizing molecular markers associated with a tomato TOSPO Resistance phenotype.

Tomato plants exhibiting resistance to tomato chlorosis virus and Fusarium oxysporum f. sp. lycopersici race 2 are provided, together with methods of producing, identifying, or selecting plants or germplasm with a tomato chlorosis virus and Fusarium oxysporum f. sp. lycopersici race 2 resistance phenotype and lacking an undesirable cold sensitivity trait. Such plants include tomato plants comprising recombinant genomic regions conferring disease resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed disease resistance alleles, are further provided.

Provided are tomato plants having fruit with red and yellow segments that appear across the fruit from the internal seed area to the most external layer of the epidermis. The present invention discloses that this phenotype, designated Arlecchino, is linked to insertion mutation within the Phytoene synthase 1 (Psy1) gene.

The present invention relates to intergeneric hybrid plants of Zinnia elegans and Tagetes erecta and methods for making the same. The invention further relates to methods for producing intergeneric hybrid plants of Z. elegans and T. erecta containing in their genetic material one or more transgenes and the intergeneric hybrid plants produced by that method. The invention also relates to transferring desirable characteristics from one genera to the other, as well as creation of new unique characteristics not found in either of the parent genera alone. The invention further relates to methods for producing intergeneric hybrid plants of Z. elegans and T. erecta derived from intergeneric hybrid plants of Z. elegans and T. erecta and to the plants produced by the method.
