Tiffanyyy ü Tiffany is a new spring bean variety from LSPB and is currently a candidate

variety in Recommended List trials.

ü Initial results show that it has comparable high yields to other leading spring bean varieties.

ü Tiffany is distinguished by a high protein content. Due to the variety’s low

Vicine and Convine content, Tiffany is particularly suitable for feeding to laying hens.

ü Tiffany has medium to early maturity and good standing power.

Backgroundnotestakenfromresearchpaper:

• Vicine and convicine are anti-nutritional compounds that accumulate in the cotyledons of faba beans.

• When humans consume beans with high levels of these compounds, it can cause a

condition called favism in individuals harbouring a deficiency in the activity of their glucose-6-phosphate dehydrogenase. When faba beans are used in animal feeds, there can be effects on performance.

• These concerns have resulted in increasing interest within plant breeding in

developing low vicine and convicine faba bean germplasm. • Work is in progress in developing a rapid and robust screening method for vicine

and convicine, capable of distinguishing between faba beans that are either high (wild type) or low in vicine and convicine.

• Biochemical assay and spectral data can be used to confirm the identity of vicine

and convicine. This method could be readily adopted in other facilities and open the way to the efficient exploitation of diverse germplasm in regions where faba beans play a significant role in human nutrition.
