Abstract: In this study, bottle gourds [Legenaria siceraria (Malign) Stanley] genotypes were collected from different part of Turkey and core collection was established based on morphological characteristics. In collection studies, 380 bottle gourd genotypes were collected under frame work of two different projects from 2003 to 2011from different region of Turkey. Additional 38 bottle gourd genotypes were introduced from international genbanks. The collected bottle gourds were grown for morphological characterization and seed multiplication in Alata Horticultural Research Station of Ministry of Food, Agriculture and Livestock in Erdemli-Mersin in 2012. Seeds were produced in 324 genotypes by selfing and the genotypes were morphologically characterized from seedling stage to seed stage. Significant morphological variation was determined in Turkish bottle gourd germplasm with respect to morphological traits. Important variation was recorded in morphological traits such as fruit size, fruit length (5 - 175 cm), fruit shape (flat-elongate), seed size (3,8 g/100 seeds - 38 g/100 seeds) among accessions. Principle component analysis was done and grouping was recorded. However, among the studied accessions, no apparently distinct patterns such as geographical origin were detected. This may suggest that the accessions have been introduced to Turkey from multiple locations and/or their diversity had been distributed almost evenly across the Turkey. Based on our results from the morphological characterization, 100 genotypes were selected to develop a core collection in order to represent most of the genetic diversity of all accessions.
