Determination of promising native Feijoa (Feijoa sellowiana Berg.) genotypes from Sakarya Region in Turkey

This study was conducted to determine Feijoa genotypes grown within seedling population in Sakarya region. In the study, approximately 300 Feijoa plants were surveyed. In these plants, 28 genotypes were labelled and evaluated. Phenological and pomological researches on these genotypes were made for two years. As a result of this study, 16 Feijoa genotypes were selected according to the weighted ranked method in this population. It was determined that fruit weight, fruit length, fruit width and shape index of the selected Feijoa genotypes changed from 21.66 to 40.00 g, 27.74 to 59.95 mm, 23.42 to 39.43 mm and 0.51 to 0.90, respectively. It was deternined that pH and total soluble solids in pulp of Feijoa genotypes varied from 2.84 to 4.55 and 10.00 to 16.00%, respectively. Flowering in the genotypes began in the last week of May and ended in the first week of July. Harvest time of the genotypes began in the second week of October and ended in the last week of November. In addition, it was determined that table properties of both selected and non selected Feijoa genotypes were lower than those of standard Feijoa varieties. However, because of the taste, aroma and yield properties of the selected Feijoa genotypes, studies should be continually done in the next stages of these genotypes.
