Seed production and plant breeding services: soybean



Plant breeding, Research and Seed production: Soybeans.

We have experience in all facets of plant breeding, research and commercial seed production for conventional, specialty, and transgenic soybeans. Our satisfied customers include plant breeders and researchers from prominent American and Canadian seed companies and universities.

Crossing nurseries: Specialized teams of hard-working, reliable college students conduct over 3000 successful crosses each year.

• F1 plants: Up to 300 seeds per plant possible with space planting.

• Generation advancement: Single seed descent, single pod descent, bulk harvest.

• Maturity Separations: Our published research has shown high correlations for maturity with Northern Hemisphere locations.

• Progeny rows: For seed increase and purification.

• Yield test: With a rank correlation of 0.83 between our location and the Northern Hemisphere, our yield testing trials data have gained the trust of soybean breeders across the USA and Canada.

• Pilot seed productions: The safety and predictability of our irrigated, high-yielding growing conditions is what you need when seed is scarce and extremely valuable.

• Large seed increases: Our commitment to honesty and confidentiality, our strategic location and the fact that Chile is not a commercial producer of soybeans, guarantee the security for your new releases.

• Transgenic testing: You have potential new transgenic releases but you need data to make decisions about different events. We can test your materials under the safest and most demanding conditions and send you the data to assist you in making safe decisions for release. Our biosecurity protocols go beyond what the authorities demand.

• Importing Transgenics: We can assist and represent you before Chilean authorities in order to obtain permission to grow new transgenic materials.

• Marker Assisted Selection: If you are using marker assisted selection, we can provide you with 100% positive identification of each individual planted. You lab does the selection while we grow your plants, then you e-mail us the list of the selected material for harvest.

• DNA Extraction: If you need DNA/RNA samples for selection or research, we can harvest and send you dried and properly labelled leaves for extraction. Alternatively, extraction can be done in Chile. Later, those plants you are interested in can be harvested for seed.

• Specialty soybeans: We can grow your non-transgenics soybeans in transgenic-free fields (fields that have never been planted with transgenic crops).
