Quality control produces clean maize seed at small seed company Bidasem
Clean maize seed piles up in the seed processing plant at Bidasem, where it has been visually examined and manually sifted by workers, picking out material such as damaged or spoiled seed or pieces of cob. After initial cleaning and sorting, all seed that goes through the plant passes through quality control. If a sample from a batch is found to more have more than 2% impurities, they are either separated out by hand like this or using a gravity table. The batch is then resampled to ensure a clean bill of health to continue processing.
Bidasem is a small seed company based in the central Mexican plains region known as the Bajío. It produces approximately 10,000 bags of maize seed a year, each holding 22.5kg, as well as producing wheat and oat seed and marketing seed of other crops. Despite their small size, Bidasem and similar companies play an important role in improving farmers’ livelihoods. “Our aim is to provide farmers with quality seed at accessible prices, that is adapted to the conditions we have here in the Bajío. It’s a great satisfaction, when farmers achieve the yields they need,” says director general María Esther Rivas.
“Without CIMMYT, we couldn’t exist,” says Rivas. She sells four different maize hybrids, all formed from freely-available CIMMYT parent lines. “Really the most important thing is to produce your own hybrids, and for us it wouldn’t be possible if we didn’t have the germplasm from CIMMYT. What we’re currently producing is 100% CIMMYT.” The relationship between Bidasem and CIMMYT is now deepening through participation in the MasAgro initiative, which includes training courses for seed companies and collaborative trials to evaluate the best seed.
