The present invention provides an interspecific Helianthus plant comprising a genetic determinant responsible for an indeterminate phenotype. Methods of making said plant are also provided.

Isolated nucleotide sequences mutated by insertion encoding a truncated sunflower oleate desaturase protein, truncated protein, methods, procedures and uses. The isolated nucleotide sequences comprise an insertion that includes a stop codon, and wherein the sequences encode a truncated sunflower oleate desaturase protein. The truncated sunflower oleate desaturase protein may be for example the sequence shown in SEQ ID No: 1 or SEQ ID No: 2.

The problem solved by the present invention is to provide a high-stearic acid sunflower line. This problem is solved by a sunflower seed comprising a sequence insertion mutation on the 3′ side from the TATA box and on the 5′ side from the start codon of a stearoyl-acyl carrier protein desaturase 17 (SAD17) gene.

The present disclosure provides a novel sunflower variety. The sunflower plant of the present disclosure is grown from a seed of a sunflower plant identified by Accession No. FERM BP-22444, Accession No. FERM BP-22445, Accession No. FERM BP-22446, Accession No. FERM BP-22447, Accession No. FERM BP-22448, Accession No. FERM BP-22449, Accession No. FERM BP-22450, or Accession No. FERM BP-22451.

The present invention provides an interspecific Helianthus plant comprising a genetic determinant responsible for an indeterminate phenotype. Methods of making said plant are also provided.

A new and distinct variety of Helianthus plant having a compact growth habit and large, yellow colored blooms.

A new and distinct variety of Helianthus plant having a compact growth habit and large, yellow colored blooms.

This invention relates to methods for identifying sunflower plants that having increased Orobanche resistance. The methods use molecular markers to identify and to select plants with increased Orobanche resistance. Maize plants generated by the methods of the invention are also a feature of the invention.

Helianthus annuus are susceptible to powdery mildew caused by fungi in the order Erysiphales. The present invention relates to novel Helianthus interspecific hybrids containing a genetic resistance to powdery mildew. The present invention also relates to methods for creating novel Helianthus interspecific hybrids containing a genetic resistance to powdery mildew and Helianthus interspecific hybrids produced by the method.

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.
