New Stress-Tolerant Rice Varieties Rolled Out for Africa by Rice Experts


The Africa-wide Rice Breeding Process Pressure, convened by the Africa Rice Middle (AfricaRice), has just lately nominated six varieties with improved tolerance to environmental stresses as ARICA, which stands for Africa Rice Varieties for Africa.

“This is the second series of nominations since the ARICA brand was launched in 2013 to offer farmers a new generation of high-performing rice varieties for Africa,” stated Dr. Moussa Sie, AfricaRice Senior Breeder and Breeding Process Pressure Coordinator.

The ARICA varieties are chosen via a rigorous multi-environment testing course of together with regional and nationwide trials in addition to participatory varietal choice involving farmers.

To be eligible for nomination as ARICA, a range will need to have a major benefit over the benchmark in a area over 3 years and should be backed by strong information. Improved rice varieties which can be authorised for launch by international locations are additionally thought-about.

Primarily based on these standards, the next six stress-tolerant ARICAs had been nominated, one in every of which is especially notable because it combines tolerance to 2 stresses, iron toxicity and chilly.

For Rain-fed and Irrigated Lowland Ecologies

  1. WAS 21-B-B-20-4-3-3: Iron toxicity tolerant (recognized for launch in Ghana) / Chilly tolerant (recognized for launch in Senegal).
  2. WAT 1046-B-43-2-2-2: Iron toxicity tolerant (launched in Burkina Faso and recognized for launch in Guinea).
  3. SIM2 SUMADEL: Chilly tolerant (recognized for launch in Mali)
  4. WAS 200-B-B-1-1-1: Chilly tolerant (recognized for launch in Mali)

For Rain-fed Lowland Ecology

  1. IR75887-1-3-WABI: Iron toxicity tolerant (launched in Guinea and recognized for launch in Ghana)

For Mangrove Ecology

  1. IR 63275-B-1-1-1-3-3-2: Salt tolerant (launched within the Gambia)

The varieties had been evaluated via the challenge Stress-Tolerant Rice for Africa and South Asia (STRASA), which helps farmers who produce their crop beneath predominantly rain-fed circumstances, by which stresses equivalent to drought, flood, chilly, salinity and iron toxicity cut back yields.

The STRASA challenge is being applied by the Worldwide Rice Analysis Institute (IRRI) and AfricaRice in partnership with nationwide packages with help from the Invoice & Melinda Gates Basis. It covers 18 international locations in Africa.

“it’s wonderful to see that products of the first two phases of the STRASA project in Africa have now reached the stage to move into farmers’ fields,” stated Dr. Gary Atlin, Senior Program Officer, Invoice & Melinda Gates Basis on the current STRASA assembly held at AfricaRice in Cotonou, Benin to plan the third section of the challenge.

“I am also impressed by the AfricaRice Breeding Task Force testing network, which it has set up in partnership with the national systems as it is a great conduit for moving improved materials into farmers’ fields,” Dr. Atlin added.

The STRASA challenge is utilizing standard plant breeding mixed with molecular breeding to develop stress-tolerant supplies. “Incorporating stress tolerance into popular high-yielding varieties has proven to be a very effective approach”, defined Dr. Baboucarr Manneh, AfricaRice Irrigated Rice Breeder and STRASA-Africa Coordinator.

Greater than 30 stress-tolerant rice varieties have already been launched in 9 African international locations with help from the STRASA challenge, in accordance with Dr. Manneh. “However as they were developed before the launching of the ARICA brand, they were not nominated as ARICAs.”

By means of the challenge, STRASA companions have produced greater than 15,000 tonnes of improved seed between 2008 and 2012 and distributed to farmers. Greater than a 1000 scientists, technicians and farmers have been skilled in improved rice cultivation methods, seed manufacturing, new breeding strategies and seed enterprise administration.

Hailing the event of the stress-tolerant ARICA varieties as “a revolution”, rice seed producers equivalent to Madame Peinda Cisse from Senegal and Mr. Abdoulaye Sawadogo from Burkina Faso requested the challenge to additionally present to farmers improved drought-tolerant rice varieties to assist them address the affect of local weather change.

“One of the key impact points for STRASA will be the quantity of seed produced and disseminated to farmers. As seed production continues to be a major bottleneck in Africa, the main thrust of our recent STRASA meeting was to help countries develop seed road maps,” stated Dr. Manneh.

The challenge is linking up with varied companions, together with non-governmental organizations, such because the Alliance for a Inexperienced Revolution in Africa (AGRA), Catholic Reduction Companies (CRS) and BRAC in addition to seed enterprises, equivalent to FEPRODES and NAFASO, for dissemination of improved seed in Africa.

“We have many stress-tolerant rice varieties in the pipeline and we will strengthen our collaboration with development partners who have the capacity for rapid delivery of improved rice varieties to our farmers,” stated Dr. Manneh.

“AfricaRice has developed an automatic monitoring and analysis (M&E) instrument, which will likely be used to trace diffusion of recent applied sciences.
