The invention relates to improved Brassica species, including Brassica juncea, improved oil and meal from Brassica juncea, methods for generation of such improved Brassica species, and methods for selection of Brassica lines. Further embodiments relate to seeds of Brassica juncea comprising an endogenous oil having increased oleic acid content and decreased linolenic acid content relative to presently existing commercial cultivars of Brassica juncea, seeds of Brassica juncea having traits for increased oleic acid content and decreased linolenic acid content in seed oil stably incorporated therein, and one or more generations of progeny plants produced from said seeds.

The present disclosure provides lettuce plants exhibiting resistance to downy mildew. Such plants may comprise novel introgressed genomic regions associated with disease resistance from L. virosa. 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 disclosure provides seed and plants of downy mildew resistant Impatiens plants. The present disclosure thus relates to the plants, seeds, and tissue cultures of downy mildew resistant Impatiens plants, to methods for producing a downy mildew resistant plant of the present disclosure by crossing such plants with themselves or with another Impatiens plant, such as a plant of another genotype, variety, or cultivar, and methods of identifying downy mildew resistant Impatiens plants. The present disclosure further relates to seeds and plants produced by such crossing. The present disclosure further relates to parts of such plants. The present disclosure also relates to methods of identifying an Impatiens plant having resistance to downy mildew.

The present disclosure is in the field of plant breeding. The disclosure provides methods for breeding corn plants having a brachytic trait using marker-assisted selection. The disclosure further provides brachytic germplasm, markers associated with a brachytic trait for introgressing the trait into elite germplasm in a breeding program. This disclosure also provides brachytic or dwarf elite corn varieties having yield equal to or higher than conventional non-brachytic corn varieties.

The present invention relates to the field of lettuce breeding, in particular to Quantitative Trait Loci for resistance against the lettuce aphid Nasonovia ribisnigri biotype Nr:1 and to cultivated lettuce comprising one or more of these Quantitative Trait Loci.

The disclosure relates to Calibrachoa plants comprising a double-flowering characteristic and a dwarf growth characteristic, methods for generating said plants, and molecular markers corresponding to the double-flowering and dwarf growth traits.

The present invention relates to the field of plant breeding and disease resistance. More specifically, the invention includes a method for breeding corn plants containing quantitative trait loci that are associated with diplodia ear rot (DER), a fungal disease associated with Stenocarpella spp. The invention further includes germplasm and the use of germplasm containing quantitative trait loci (QTL) conferring resistance for introgression into elite germplasm in a breeding program for resistance to DER.

Tomato plants exhibiting resistance to Stemphylium are provided, together with methods of producing, identifying, or selecting plants or germplasm with a Stemphylium resistance phenotype and lacking an undesirable small fruit size trait. Such plants include tomato plants comprising introgressed genomic regions conferring disease resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed disease resistance alleles, are further provided.

A method of producing a Gramineae plant, the method comprising (a) expressing in a Gramineae plant or plant cell expression of a polynucleotide encoding OLLS1 as set forth in SEQ ID NO: 12 or 13 or a homolog thereof capable of increasing stigma length of the Gramineae plant, wherein when the expressing is by crossing the plant with another plant expressing the polypeptide, selecting for stigma length is performed using markers located between ST87 to ST99; and (b) growing or regenerating the plant.

The present disclosure discloses the use of gene encoding gibberellin 3β-hydroxylase of G. max, GmGA3ox1. The use of gibberellin 3β-hydroxylase gene of G. max, GmGA3ox1, set forth in SEQ ID NO:1, in genetic engineering of seed weight of Arabidopsis thaliana and Glycine max. In A. thaliana, overexpression of GmGA3ox1 can complement the low seed weight phenotype of atga3ox1 mutant. In G. max, overexpression of the excellent haplotype of the gene can significantly improve the seed weight of G. max.
