As part of the Bioleft’s participatory breeding experiments, Enrico Cresta, an organic farmer and member of Bioleft, selects and develops his own open-pollinated (OPV) and GMO-free corn variety, adapted and improved to the organic conditions of his \u201cAltos Verdes\u201d establishment, located in the Cordoba province. <\/p>\n\n\n\n

Enrico has been dedicated to organic farmers for about 30 years, and in 2015 he started to select and develop his corn variety, adapted and improved under organic conditions and GMO-free. He departed from local materials derived from \u201cChucul\u201d seed,  developed by farmers like himself, freely crossed with hybrids and commercial varieties to increase the genetic variability and apply mass selection techniques. In 2018, he obtained a hard yellow corn OPV, which he named \u201cOriginal\u201d, but it was contaminated with GMO materials. Despite being detected in low value (nearly 1%), it had to be eliminated because it was not accepted in the organic approach. <\/p>\n\n\n\n

In this post, we share the 2023\/2024 season trial. Enrico\u00b4s trial consisted of a 25 m x 7m plot, planted in mid-October 2023, with a plant spacing of approximately 15 cm and a furrow spacing of 70cm. This distance ensured rapid furrow coverage and better weed competition, while it allowed mechanical weed control using a hoe. The early planting date was intended to offset the flowering of his corn with that of neighbouring corn to avoid contamination with pollen that might contain transgenic material in its composition. In addition, he planted near a mill, which allowed him to accompany the early stages of corn development with irrigation. To protect himself from birds without damaging them, the entire plot was protected by a net. <\/p>\n\n\n\n

The presence of GMOs goes against organic farming principles, so materials in which GMOs are detected should be discarded. For this reason, all Enrico plants were evaluated before flowering. For the analysis, 10 samples were taken from a pool of 60 plants each. As an outcome of the tough work of de-transgenization, the result of the sample was 100% negative, and, with this information, Enrico ensured that his corn was free of OGM events.\u00a0<\/p>\n\n\n\n


In this video<\/a>, Enrico shows us his trial and we can observe the state of his plants and general crop conditions.\u00a0\u00a0<\/p>\n\n\n\n
