Beets: Working toward a better tolerance of cercospora

The Permanent Technical Selection Committee (CTPS), composed of professionals and representatives of the administration, has recently proposed to the Minister of Agriculture the registration of 20 new varieties of beets to the official catalog.

After reviewing the experimental results from 2017-2018, the advances in the tolerance to cercospora have allowed the registration of 9 varieties tolerant to rhizomania, 7 varieties tolerant to nematodes, and 4 varieties tolerant to brown rhizoctonia. This year, 22 varieties were rejected.

All the varieties registered are tolerant to cercospora, a disease that affects the leaves. “The indicator level was quite high, which explains the small number of varieties registered this year,” notes Bruno Richard, secretary of the “industrial endives and beets section” of CTPS.

The producers are pleased with the yield progress in the cercospora experiments. The Jellera KWS variety, for example, shows remarkable characteristics in the official trials. These results will have to be confirmed in the post-registration tests which will be carried out this year in the ITB network and sugar plant agronomic services (SAS). Of the 20 newly registered varieties, ITB chose to integrate 17 in the 2019 trials, the results of which will be published in November.
