Abstract
As a result of the hybridization of ?Sevgi? and ?Ka?ka? cultivars with
?Fortuna? cultivar, which are bred within Cukurova University, superior
characteristic strawberry genotypes with codes of ?33?, ?36? and ?61? were
selected. In this study, these genotypes and three cultivars commonly grown
in the Mediterranean region were compared in terms of yield, fruit size and
taste determining parameters (sugar and organic acids) at different harvest
date monthly under Mediterranean climate condition. The highest yield was
measured generally in April, while the genotype-dependent yield varied
between 628.9 g / plant (?36?) and 951.5 g / plant (?Fortuna?). Besides,
average fruit weight varied (6.8 - 23.9 g) during the season depending on
the harvest date and genotype. The sucrose content varied between 0.06 g /
100 g and 4.83 g / 100 g, while the ascorbic acid content showed huge
variation depending on the harvest date and genotype with 1.5 mg kg and
393.8 mg/kg values. Generally, the 33-advanced selection attracted attention
with its relatively high yield, glucose, fructose, and ascorbic acid
content. As a result, genotype and environmental conditions are quite
determinant in terms of observed parameters in strawberry cultivation.
Furthermore, biotechnological methods could be utilized to shorten breeding
time in classical crossbreeds to improve the deficiencies of these
genotypes.
