The present study was conducted with the objective of conducting an agro-morphological characterisation of 22 eggplant genotypes collected from the Central Anatolia region, in addition to the subsequent evaluation of their genetic relationships. For the agro-morphological characterisation, observations and measurements were made for 29 traits (24 qualitative and 5 quantitative), which were determined by considering the criteria specified by UPOV and IPGRI. Principal component analysis and cluster analysis, obtained as a result of the analysis of the data belonging to the morphological traits, determined the level of genetic relationship between the eggplant genotypes in the gene pool. In the Principal component analysis, ten principal component axes explained 75.80% of the total variation, while in the cluster analysis, the distance range between the genotypes varied between 1.46 and 11.03 and the mean coefficient of the dendrogram (mean similarity) was 0.514 and the genotypes were divided into eight groups. As a result of the study, a significant morphological variation was found among the eggplant genotypes and it is believed that the data obtained will be an important source for similar researches such as sustainable plant breeding and conservation of genetic diversity.

Orta Anadolu patlıcanının agro-morfolojik karakterizasyonu

Öz

Bu çalışma, Orta Anadolu bölgesinden toplanan 22 patlıcan genotipinin agro-morfolojik karakterizasyona ek olarak genetik ilişkilerinin değerlendirilmesi amacıyla yürütülmüştür. Agro-Morfolojik karakterizasyon için UPOV ve IPGRI tarafından belirtilen kriterler dikkate alınarak belirlenen 29 adet özelliğe (24 adet kalitatif; 5 adet kantitatif) ait gözlem ve ölçümler yapılmıştır. Morfolojik özelliklere ait verilerin analizi sonucunda gerçekleştirilen temel bileşen analizi ve küme analizi ile gen havuzundaki patlıcan genotipleri arasındaki genetik ilişki düzeyi belirlenmiştir. Çalışma sonucunda seçilen 46 genotip üzerinde gerçekleştirilen temel bileşen analizinde, on temel bileşen toplam varyasyonun %75.80’ini açıklamıştır. Küme analizinde ise genotipler arasındaki mesafe aralığı 1.46 ile 11.03 arasında değişiklik göstermiştir. Oluşturulan dendrogramın katsayı ortalaması (benzerlik ortalaması) 0.514 olarak belirlenmiş ve genotipler sekiz gruba ayrılmıştır. Çalışma sonucunda patlıcan genotipleri arasında önemli bir morfolojik varyasyon tespit edilmiş ve elde edilen bu veriler sürdürülebilir bitki ıslahı ve genetik çeşitliliğin korunması gibi benzer araştırmalar için önemli bir kaynak oluşturacağı düşünülmektedir.
