The number of days from emergency to maturity varied between 75 (Velox, Rosara varieties)
and 95 (Fabula variety). The highest yields were realized by the latest varieties (Fabula and Rosara),
but Carrera variety which is an early variety realized also a high yield. Because the year 2007 was
much warmer and dryer than 2006, the growth period was smaller with 5 days in average.
During the growth period, there were observed some specific characteristics that can be useful for the
potato growers (table 1).

Conclusions
4. The highest yield as average in the studied years (2006 and 2007) and under the specific
conditions from South Romania were obtained at the Fabula variety (60.3 tons per hectare), this
been determined especially by the weight of the tubers and not by the number of tubers.
5. High yield (55.3 tons per hectare) was realized also at the Rosara variety, but in this case the
yield was determined by the number of tubers per plant and not by the weight of tubers.
6. Also, high yield (53.9 tons per hectare) was realized at the Carrera variety, this been determined
both by number of tubers per plant and weight of tubers.
7. Varieties indicated for chipping (Lady Claire and Lady Rosetta) realized smallest yields
compared with the other varieties.
8. Also, varieties for chipping realized a high number of small tubers per plant.
