Reaches high dry matter levels and low sugars early in the season. This makes Lady Rosetta the excellent early season and medium term storage crisping variety; red skinned, round shaped crisp potato with rather shallow eyes; also very suitable for starch and mashed potatoes; the crop is reliable with high marketable output and uniform size distribution. The development of the crop is rapid and with good husbandry techniques will produce excellent results in a range of conditions; Lady Rosetta has a good drought tolerance, the crop will benefit from good irrigation; rapid leaf development with good ground cover; parentage: Cardinal x (VTN)2 62-33-3.

 

Advice:
Wait for eyes waking up before planting. Start late blight control in time.
Wait for a set skin before harvest. After harvest, dry the potatoes by ventilation.
Avoid black spot
