A recent study funded by the Bill & Melinda Gates Foundation and the UK Foreign, Commonwealth & Development Office (FCDO) has used DNA fingerprinting technologies to track the variety of wheat grown in Nepal and Bangladesh. The research, which overcame previous identification challenges with a 30% accuracy rate, found that in Bangladesh, BARI Gom 25 was the most popular variety, while in Nepal, 'Gautam' and 'Vijay' varieties were favored. The study highlights the need to retire low-yielding, disease-susceptible varieties and develop strategies for adopting new, improved ones. It also underscores the importance of maintaining varietal purity and improving seed management to ensure uniformity and accurate tracking of wheat adoption rates.

By Vijay Paranjape, Poornima Gade, Rijuta Garapaty, Rituparna Majumder & Maricelis Acevedo Wheat is one of the most widely grown crops globally, yet for many farmers the exact variety of wheat growing in their fields is a mystery. For the first time, extensive studies using DNA fingerprinting technologies are revealing granular detail about the kinds of wheat growing in Nepal and Bangladesh and providing insights to boost the productivity of this crucial food security crop. Conducted by researchers from Cornell, Sathguru Management Consultants, and National Agricultural Research Centers in Bangladesh and Nepal, the studies not only helped identify the popular varieties but also uncovered the widespread use of older and in some cases decommissioned varieties. The assessment will not only contribute to the understanding of the impact of crop improvement in food security and income growth but also aid research prioritization and inform variety replacement strategies.
