Doğal Meralanrdan Toplanan Ak Üçgül (Trifolium repens L.) Genotiplerinin Performanslarının Belirlenmesi

Bu çalışmada Doğu Anadolu mera alanlarından toplanan ak üçgül(Trifolium repens L.) genotiplerinin fizyolojik ve morfolojik karakterlerinin incelenmesi amacıyla yapılmıştır. Ak üçgül genotiplerinin benzerlik ve farklılıkları principle component analizi yoluyla yapılmıştır Bitki boyu bağımlı değişken olarak kabul edilerek genotipler değerlendirilmiş, genofipler arasındaki farkı ise en iyi şekilde ortaya koyan model olarak bu model kullanılmıştır. Sonuç olarak sadece bitki özellikleri arasında değil bitki genotipleri arasında da geniş bir varyasyon tespit edilmiştir. Diğer bir deyişle bu farklılık genetik bir varyasyondur. Ak üçgül genotipleri içerisindeki genetik farklılık ıslahta bitki seçiminde yardımcı olacaktır. Bu çalışma bitki ıslahında dik ve yatık bitkilerin seçileceğini göstermiştir. Genotipler bitki karakteristiklerine göre belli başlı beş gurupta toplanmıştır.

Determination of Genotypic Performances of White Clover (Trifolium repens L.) Collected from Natural Pastures

This study was conducted to fine out morphological and physiological characteristics of white clover genotypes obtained from different location of Eastern Anatolia pastures. Similarities/dissimilarities in white clover genotypes and plant characteristics' by principle components analysis were made. Plant height as a depended variable the effect of criteria on plant height and critic the best model to calcify genotype were made in white clover. As a result, wide variations were determined in not only plant characteristics but also genotypes. This was variation in other word genetic differentiations. Genetic differentiation on genotypes in white clover could help plant selection in white clover breeding present. Study showed that white clover breeding may be based on erect and prostrate plant selection. Plant characteristics and genotypes were classified in five certain groups on plant height.
