Öğe Evaluation of fruit firmness among the segregation population strawberries developed from ‘Ottoman’ × ‘Camarosa’(International Society for Horticultural Science, 2019) Serçe, S.; Gündüz, K.; Çürük, S.Turkish strawberry production has an increasing trend. ‘Ottoman’ is one of the Turkish strawberry genetic resources with unique horticultural attributes such as aroma content. However, fruit firmness of ‘Osmanlı’ is low. In this study, a segregation population having 340 individuals, produced from ‘Ottoman’ × ‘Camarosa’ were characterized for many horticultural traits for two years. The hybrids were grown in an annual hill cultural system with summer planting on an open field conditions and flowering and runnering dates were recorded. Flower and leaf characteristics were determined in December in both experimental years, while pomological traits of fruit width, length and weight, soluble solids, fruit firmness, fruit external and internal colors were determined periodically during the whole experiment. A great deal of diversity was recorded among the hybrids for the most of the traits evaluated. For example, fruit firmness ranged between 0.2 and 1.5 kg cm-2; while the ranges for soluble solids, total fruit number and yield were 4.0-15.0%, 2-192 and 11.9-1220.8 g, respectively. The data from two experimental years were compared using regression analysis. Except petiole length, leaf width and length, all other traits evaluated had statistically significant correlation between their two years (P=0.000-0.017). 78 individuals from this population were genotyped with 33 SSR primer pairs which had previously been proven to be informative for this population. © 2019 International Society for Horticultural Science.

Although fruit of those Vaccinium species have been collected from the nature by local inhabitants for millennium, they are not commercially cultivated. A study was carried out leading to the collection and characterization of morphological traits of those wild Vaccinium species having potential horticultural importance. Five morphologically different populations of Vaccinium wild species were collected from different habitat with diverse altitude during the land expedition of Eastern Black sea region of Turkey. After extensive literature search, focusing on their morphological characters, these Vaccinium populations were identified as Whortleberry (V. acrostaphylos), billberry (V. myrtillus) and bog bilberry (V. uliginosum). Among the five populations three were highbush type V. acrostaphylos and two lowbush type species identified as V. myrtillus and V. uliginosum. Twelve horticulturally important morphological traits like leaf weight, petiole length, leaf width, leaf length, leaf color (upper side), leaf color (lower side), fruit weight, fruit width, fruit length, fruit crown width, seed number and fruit color have been recorded and analyzed in details. Significant differences observed among the populations and species level regarding the analyzed traits. It is evident that our initial result could be highly valuable for further characterization and improvement of wild or cultivated Vaccinium species in Turkey. © 2019 International Society for Horticultural Science.

For this purpose, the better understanding of the flower bud formation in the strawberry cultivars from different background and determination of plating material types and planting dates are required. We investigated meristems coming from different locations (Amasya = high elevation and Antakya = low elevation) and sampled in four different dates (1 September, 15 September, 1 October and 15 October) using ‘Cal Giant–3’, ‘Camarosa’, ‘Festival’, ‘Kabarla’ and ‘Sweet Charlie’ cultivars; 2). During the investigation of the meristems, five plants of each of the high and low land locations’ mother, and daughter plants and plug planting material was observed. The plug planting materials produced in the low and high land locations were planted on the planting dates of 1 September, 15 September, 1 October and 15 October and the fruits were subjected to the pomological analyses for ‘Camarosa’ and ‘Festival’. The planting dates had statistically significant differences for ‘Festival’. Although there were some statistically significant differences among the pomological traits tested, constant patterns for all periods and cultivars resulted from either planting material type or planting dates was not recovered. The results indicated that to increase the early yield in strawberry production, studies targeting to identify cultivars with low chilling requirement which could form flower buds under less favorable conditions may result in more advantageous results. © 2019 International Society for Horticultural Science.
