Description:
Selected from Ben Shermen. A selection of 100 non-bolting bulbs was made from a planting with >90% bolting. Bulbs were selfed, leaving one umbel of each to intercross. Tests on self progeny indicated one bulb selection (7933) to be superior in bolting resistance and bulb shape. "NuMex Sundial" and "NuMex Suntop" were derived by two cycles of selection from the open-pollinated (intercross) progeny from 7933.
