As a result of a partnership between Embrapa and CRN (Campus Regional do Noroeste), from UEM (Universidade Estadual de Maringá), table cassava (cassava) BRS 429 was launched this week for São Paulo and Parana, the first table variety recommended for the territory. Sao Paulo.

Alcioni Andrea da Cunha Alexander, director of CRN at UEM, commented that this is the third variety of table cassava grown in Parana by Embrapa in collaboration with the campus.

“I believe that family farming will multiply this rural product on the consumer’s table. Without the input and participation of farmers, a team of researchers, technicians, professors and CRN staff, it would not have been possible to achieve such success in this rural research,” he stressed.

The agreement between the two research institutes – Embrapa and UEM – began in 2009 and was renewed in 2021 to improve and genetically develop cassava, an important staple on the Brazilian table.

Today, cassava is grown throughout the country, with almost 18 million tons of root crops produced annually, 87% of which come from family farms.

The partnership between the two institutions has created an important bank of regionally adapted varieties to conserve their genetics and meet the needs of family farming.

The soy sanitary vacuum in Parana will last until September 10th.

The director of CRN at UEM believes that this partnership benefits the country’s producers, including those from the hinterland of Paraná and the state of São Paulo. “This is very important for our region, which consists of family farms, and the best, with high-quality vines,” he stressed.


The new variety, which has good culinary qualities and taste, is 49.76% higher than the average yield compared to commercial root crops, with a potential of over 60 tons per hectare, according to Embrapa.

Center-South Experiment Coordinator, Embrapa Cassava and Fruticulture researcher Marco Antonio Rangel explains that the new variety combines a set of characteristics that make it an excellent product.

“In addition to high productivity (in Paraná, the average yield of BRS 429 was 25.7% higher than traditional varieties, and in São Paulo the superiority reached 53.9%), it has a cylindrical, longer and longer root. gives wider commercial use (in Paraná 10.5% higher than the standard average, and in São Paulo 4.3% higher),” he lists.

The technician adds that other features of the new variety are its early maturity (it can be harvested at eight months old) and moderate resistance to major diseases such as bacteriosis and overpulling.

“It has an intense yellow flesh (preferred by consumers), a good cooking time (average 20 minutes), a mealy texture suitable for both the most common use (boiled and fried) and for making good quality pasta.”

Another characteristic that Rangel pointed out is that this variety has very good characteristics that are suitable for all types of growers, it is excellent for those who are more technical, who want to plant plots with planters, due to the vertical size of the plant , facilitating agricultural technology. .

“It also stands out for the quality of the root, which, because it is more cylindrical, allows for better commercial use, and for its taste, which is a very positive difference. We use taste categories in our sensory assessments. Good table varieties fall into the “characteristic taste” category. This one fell into the “excellent taste” category, up a notch,” he concludes.


Following the launch of cassava BRS 429, held at the UEM campus in Diamante do Norte (PR), a series of actions are planned to promote this variety in the areas of institutions and partner producers in the experiments in Paraná and São Paulo.

The forecast is that in the second semester there will also be an extension of the recommendation for cerrado, originally the Federal District and surroundings – some tests already show, for example, 30% higher productivity in relation to local varieties.


In view of the work developed by the team at the UEM campus in Diamante do Norte (PR), Embrapa chose the site where the BRS 429 variety was launched as the distribution center for seedlings.

In addition, Embrapa has licensed the variety to growers: Clona-gen Biotechnology Vegetal (SC) and Vivetech Agrociências (PR).

Since 2015, cassava growers in Paraná have varieties BRS 396 and BRS 399, derived, like BRS 429, from crosses carried out by Embrapa Cerrados (DF) and confirmed in the Central-South region by Embrapa Cassava and Fruticultura (BA) team. . (With consultants from UEM and Embrapa)
