INVESTIGATION OF STRAWBERRY CULTIVARS
ACCORDING TO INTERNATIONAL COST 863
PROGRAMME IN LITHUANIA
R. Rugienius, A. Sasnauskas
Summary
Ten strawberry cultivars and hybrid clones were investigated according to
COST863 action in 2003–2006. Strawberries were planted in two stages – at 2003
and 2004. Under the agroclimatic conditions of the middle of Lithuania cultivars
‘Salut’ ir ‘Roxana’ were the most winterhardy. ‘Irma’ and ‘Alba’ were the most
cold susceptible ones. According to our data, ‘Qeen Eliza’, ‘Irma’, ‘Salut’, ‘Alba’,
‘Roxana’ are medium early, hybrid clone (h.c.) VR96582 is medium late, h.c. 92.340.3
is late. ‘Irma’ is weekday neutral. The highest two-year (2004–2005) average yield
of first planting was received from ‘Roxana’ (19,6 t/ha) and h.c. 92.340.3 (18,5 t/
ha), the highest yield of another planting (2005–2006) – ‘Roxana’ (16,5 t/ha) and
‘Salut’ (13,8 t/ha). ‘Roxana’, h.c. 923403 and ‘Qeen Eliza’ had the biggest berries.
The best appearance was of ‘Roxana’ and h.c. 9.234.03, berry firmness – of h.c.
92.340.3, ‘Alba’ and h.c. VR96.582, best taste of ‘Irma.’ Among investigated cultivars
the most promising under Lithuanian conditions were ‘Roxana’, ‘Salut’ and
h.c. 92.340.3 strawberries.
Key words: Fragaria ananassa Duch., fertility, cold resistance, berry quality.
