by PressBrazil plans double-cropping using hybrid varieties
Double-cropping will become possible in tropical regions
New hybrid canola varieties will improve double-cropping. Scientists are developing tropical hybrids of this type of rapeseed. This will help ensure high yields.
Embrapa Agroenergia and Advanta Seeds have joined forces. Their goal is to develop the first tropical canola varieties adapted to the Brazilian climate. This project is expected to be an important milestone for the country’s agricultural sector, making it possible to:
— transform approaches to double-cropping;
— make second harvests more accessible to farmers in rural areas;
— meet the growing demand for vegetable oil and raw materials for biofuels.
This development is part of the BRSCanola initiative, which has the following main objectives:
— to create high-yielding varieties;
— increasing plant resistance to diseases, pests, and herbicides;
— to adapt to the tropical climate and local soil characteristics.
These new varieties are expected to be primarily intended for Brazil’s central and southern regions.
The role of rapeseed in the food chain
Rapeseed is a popular crop in Brazil. Key crops are concentrated in the south. However, the state imports most of its rapeseed from Australia.
The project to develop local varieties is scheduled to last two years. It is based on previous research into sustainable canola production methods. Scientists have pooled their knowledge and skills to develop varieties that are well-adapted to the country’s climate. This will increase local rapeseed oil production and expand the country’s biofuel potential.
Cultivating rapeseed also opens up new opportunities for agricultural diversification. The plan is for this crop to become the second in the crop rotation after soybeans.
Various genetic combinations developed by Embrapa and Advanta specialists will form the basis for creating new hybrids. These combinations are currently undergoing field and greenhouse trials to assess grain quality. Particular attention is being paid to the plants’ resistance to excess moisture and diseases. The main concerns are white mold, black leg, and other common threats.
The project’s success is evident in the caliber of its participants. Advanta has over 40 years of experience creating in-demand genetic materials for the agricultural sectors of many countries. The project itself has significant potential in the Brazilian domestic market.
Local producers are keenly aware of the lack of varieties adapted to regional climatic and soil conditions. This shortage limits the expansion of cultivated areas and hinders growth in yields and profitability. New developments can remove these barriers. They will enable farmers to effectively utilize land that was previously considered unfit for cultivation.
