INTA in Argentina presented two cultivars of oats resistant to leaf rust

Tridge summary

Researchers at INTA Bordenave in Buenos Aires have developed two new oat varieties, Sofía INTA and Elena INTA, which are expected to be available in the next campaign. These varieties are designed to be resistant to leaf rust, a disease that significantly reduces yield and quality, without requiring fungicides. Both varieties are highly productive and recommended for different regions within the Pampean region. These new oats will be marketed under technological linkage agreements with Baya Casal and its multiplier network, with emphasis on the importance of using legal and controlled seed for optimal production.

Sofía INTA and Elena INTA are two new varieties that are characterized by high forage productivity and excellent health. They were developed by a research team from INTA Bordenave –Buenos Aires– and will be available in the next campaign. With an area sown in the 2020/21 campaign of more than 1.4 million hectares, oats are the main winter greening. Its main destination is the production of forage in the autumn, winter and spring months, and it is also used to make forage reserves, either in silage or in hay (rolls and bales). However, it is usually susceptible to leaf rust, a parasite that causes significant losses in yield and quality of forage and grain. For this reason, INTA advances in the development of new varieties of oats, based on genetic improvement, that resist this disease without the need to apply fungicides and maintain a high production potential. "In recent years, the appearance of new races of rust broke the resistance of all oat cultivars available on the ...
