Performance of oilseed flax varieties in the southeast of Buenos Aires, Argentina
Flax (Linum usitatissimum L.) cultivation is carried out in some fields in the Southeast of Buenos Aires province and presents business opportunities, despite did not have an important amount of updated information. In the present work, experiments were carried out in three campaigns to evaluate phenology, yield components, oil percentage and dry matter production of four flax varieties recently registered in the country. The experiments were sown on July 10th of 2015, July 17th of 2019 and August 18th of 2020. Flax cultivars used were AGUARÁ INTA, CABURÉ INTA, PANAMBÍ INTA and CURUNDÙ INTA. AGUARÁ INTA and CABURÉ INTA tended to present harvest indices, yields and oil percentages that would exceed older materials, without presenting differences in their phenology. Intercepted radiation percentages during flowering were related to dry matter production and thus with seed yield. In field conditions with high rainfall during November, Caburé INTA presented higher yields, but their yield potential was not stable under restrictive conditions. Meanwhile, Aguará INTA presented a somewhat lower performance than varieties average, but with the lowest year-on-year yield variability. Increase in data collected will allow in the future to select most appropriate varieties at each field condition.
