Özet
Ülkemizde fasulye genetik kaynakları, ıslah çalışmalarında yeterince değerlendirilemediğinden, geliştirilen çeşit sayısı ve üretim miktarı yeterli düzeyde değildir. Bu nedenle, ülkemizde fasulye gen kaynakları yönünden mevcut zenginliğin yapılacak araştırmalarla ortaya çıkarılması, bunların yeni çeşit geliştirme ve alternatif tarım sistemlerinde kullanılması oldukça önem taşımaktadır. Bu çalışmada, 2015- 2016 yıllarında Türkiye’nin Batı Anadolu Bölgesi’ndeki farklı fasulye yetiştirme alanlarından toplanan yerel kuru fasulye genotipleri, 2016 yılı yetiştirme sezonunda Bolu Abant İzzet Baysal Üniversitesi deneme alanında yetiştirilmiştir. Fasulye genotipleri, IPGRI (International Plant Genetic Resources Institute) & EUCPVO (European Union Community Plant Variety Office) ve TTSM (Tohumluk Tescil ve Sertifikasyon Merkezi) tarafından belirtilen çeşit tanımlama kriterlerine göre 53 morfolojik özellik yönünden tanımlanmıştır. Fasulye genotiplerinin kalitatif ve kantitatif özellikler bakımından belirgin farklılıklar gösterdiği belirlenmiştir. Bitki büyüme özelliklerine ait korelasyon analizi sonucunda tane verimi ile bitki boyu, bitkide bakla sayısı, baklada tane sayısı arasında anlamlı ve önemli düzeyde ilişkiler tespit edilmiştir. Temel Bileşen Analizi (TBA) sonucunda incelenen 53 özellik ile ilgili olarak birbirinden bağımsız 10 adet temel bileşen ekseni elde edilmiştir. Bu eksenlerin toplam varyasyonun %68.59’unu temsil ettiği belirlenmiştir. Genotip x özellik ilişkisini gösteren biplot analizinde; genotipler, büyüme şekilleri, bakla özellikleri ve verim özellikleri yönünden ayrılmıştır. Kümeleme analizi sonucunda fasulye genotiplerinin ele alınan 53 karakter yönünden iki ana gruba ayrıldığı tespit edilmiştir. Grupların ayrılmasındaki en temel karakterin büyüme formu olduğu gözlemlenmiştir. Bu çalışmadan elde edilen verilerin, yakın gelecekte yapılacak ıslah ve genetik çalışmaların başlangıç noktasını oluşturacağı düşünülmektedir.
Common bean genetic resources cannot be adequately evaluated in breeding studies in our country, thus the number of cultivars developed and production amount are not sufficient. Therefore, it is very crucial to reveal the richness of common bean genetic resources, and to use them for the developing new cultivars and an alternative agricultural system in the country. In the present study, common bean genotypes collected from Western Anatolia Region of Turkey in 2015-2016 were grown on the experimental farm of Bolu Abant Izzet Baysal University, during 2016 growing season. Genotypes were described in terms of 53 morphological characteristics according to the type identification criteria specified by IPGRI (International Plant Genetic Resources Institute) & EU-CPVO (European Union Community Plant Variety Office) and VRSCC (Variety Registration and Seed Certification Center). It was determined that genotypes revealed significant differences in terms of qualitative and quantitative characteristics. As a result of the correlation analysis of the plant growth characteristics, it was determined that seed yield per plant was significantly correlated with plant height, number of pods per plant and number of seeds per pod. Result of Principal Component Analysis (PCA), 10 principal components axes were obtained from 53 morphological traits. These axes represented 68.59% of the total variation. Genotypes were divided in terms of growth patterns, pod features and yield characteristics in biplot analysis, which reveals genotype x trait relationship. As a consequence of cluster analysis, genotypes were divided into two main groups in terms of 53 morphological traits. It was observed that the most basic character in the separation of groups is the growth habit. It was thought that the data obtained from this study will serve as starting point for the near future breeding and genetic studies.
