Perennial Sunflower Breeding Services

INQUIRY

Sunflowers are traditionally cultivated as annuals for edible oil, animal feed, and ornamental purposes. Perennial sunflowers typically reproduce and overwinter via underground rhizome systems, re-emerging the following spring without the need for replanting. As an advanced plant biotechnology company, Lifeasible specializes in delivering cutting-edge, reliable plant breeding solutions. By combining the adaptability and stress tolerance of wild perennial sunflowers with the high-yielding, high-quality traits of cultivated varieties, we aim to provide comprehensive solutions for perennial sunflowers.

Advantages of Perennial Sunflower Breeding

  • Ecological and sustainable agriculture. Perennial sunflowers provide long-term soil cover, which reduces erosion, enhances soil organic matter, and improves water retention, making them suitable for conservation tillage and intercropping systems.
  • Resource efficiency. Deep root systems access water and nutrients from deeper soil layers, reducing irrigation and fertilizer requirements while enhancing stress tolerance.
  • Lower production costs. Long-term management reduces annual expenses for seeding, soil mechanical treatment, and seed procurement, making it suitable for low-input or marginal land utilization.

Our Service for Perennial Sunflower Breeding

Distant hybridization

Through interspecific hybridization between cultivated sunflowers and wild perennial sunflowers, perennial traits, disease and pest resistance genes, and high-yielding characteristics are combined. Molecular marker analysis enables accurate identification of hybrid progeny and selection of desirable lines.

Genomics-assisted breeding

High-throughput sequencing technologies analyze sunflower chloroplast and mitochondrial genomes to identify gene loci associated with perennial traits. Furthermore, population association studies or genomic mapping enable the identification of key gene regions controlling root architecture, tillering, overwintering, and regeneration capacity, providing candidate genes for molecular breeding and functional validation.

Tissue culture and regeneration systems

We have established comprehensive somatic embryogenesis and plant regeneration techniques, enabling rapid propagation of superior genotypes via hypocotyl and cotyledon tissue culture. Furthermore, our slow-growth technology is employed for germplasm resource conservation, ensuring genetic diversity.

Tissue culture is utilized for embryo rescue, regeneration, and somatic cell culture. Combined with speed breeding protocols, this approach minimizes generation time to accelerate selection processes.

Phenomics and high-throughput phenotyping

We employ drone-based remote sensing, multispectral or hyperspectral imaging, near-infrared and thermal imaging for high-throughput, non-destructive monitoring of growth dynamics, leaf area, drought response, and other traits. Combined with automated data processing, this enables precise selection.
