Beyond landraces: developing improved germplasm resources for underutilized species - a case for Bambara groundnut

Area of Science:

• Agricultural Science
• Plant Breeding
• Food Security

Background:

• Underutilized crops are vital for diversifying agriculture to address global food and nutrition security challenges.
• Climate change and population growth necessitate resilient agricultural systems, highlighting the importance of neglected crop species.
• Bambara groundnut (Vigna subterranea L. Verdc.) shows promise due to its drought tolerance, crucial for semi-arid environments.

Purpose of the Study:

• To present strategies for the genetic improvement of Bambara groundnut.
• To provide a guide for improving other underutilized crop species.
• To explore integrated germplasm development approaches for variety enhancement.

Main Methods:

• Review and synopsis of genetic improvement strategies for underutilized crops.
• Discussion of comparative trait studies with major crops.
• Highlighting the potential of multi-parent advance generation inter-crosses (MAGIC) for genetic analysis and variety development.

Main Results:

• Underutilized crops, often existing as landraces, require different breeding approaches compared to major crops.
• Integrated germplasm development is essential for effective genetic improvement.
• Bambara groundnut's drought tolerance makes it a key candidate for climate-resilient agriculture.

Conclusions:

• Genetic improvement of underutilized crops is critical for future food and nutrition security.
• Advanced breeding techniques like MAGIC can unlock the potential of neglected species.
• Bambara groundnut serves as a model for developing resilient agricultural solutions.
