The genetic relationship between some strawberry cultivars and F₁ population derived from these cultivars

In this study, Osmanli strawberry cultivar that has specific and superior characteristics was used as a maternal parent to create crosses with three local (‘Karacilek’, ‘Tuylu’, and ‘Deli’) and three standards (‘Kabarla’, ‘Sweet Ann’ and ‘Sweet Charlie’) strawberry cultivars as paternal parents.
Fifty-two F₁ genotypes resulting from these hybridization studies, their parents were selected for studying the genetic distances among them and with Fragaria chiloensis. Fourteen UBC-ISSR primers in which polymorphism levels were determined, were used. 76 DNA bands were obtained in total and 60 of them were polymorphic.
After the evaluation of ISSR-PCR bands, the data were analyzed in Popgene32 and MEGA5.0 packaged software and a dendrogram was obtained according to the UPGMA method.
The dendrogram was separated into two major groups at the 20% difference level, one large and one small group. Fragaria chiloensis, ‘Tuylu-2’ local cultivar, CC48, and CA97 F₁ genotypes participated in the small group while the other F₁ genotypes and parents participated in the large group.
This suggests that ‘Tuylu’ local cultivars were closer to F. chiloensis than most genotypes issued from ‘Osmanli’ cultivar.
