Plant breeding, Research and Seed production: Corn.

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

• Crossing nurseries: Data-driven nurseries can be conducted because Los Andes has the highest GDD accumulation in Chile (see climatic conditions) permiting timely harvesting in time for planting in the USA/Canada. Specialized teams of hard-working, reliable college students carry out your crossing schemes including: Self pollinations, cross pollinations (simple or complex, special requirements can be accommodated with consultation), sib pollinations, bulk pollinations, topcrosses.

• Yield test: Yield potential of your experimental hybrids can be estimated under stress-free conditions. Commercial yield of US-bred corn varieties at our location usually exceed 18 tons/ha (264 bu/A).

• 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 association with top-farmers guarantee optimum yields of your increases.

• 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 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 properly labelled leaves for extraction. Alternatively, extraction can be done in Chile. Later, those plants you are interested in can be harvested for seed.

• Conventional Corn: We can grow your conventional corn in transgenic-free fields (fields that have never been planted with transgenic crops).
