Türkiye'de yayılış gösteren pancar (Beta L.) türlerinin değerlendirilmesi: Beta seksiyon beta

Beta. (pancar) türleri kültür pancarlarının önemli genitörleridir. Türkiye, Beta türlerinin Beta ve Corollinae seksiyonlarının orijin merkezlerinden biri olarak bu türlerin önemli bir genetik tabanına sahiptir. Bu nedenle Türkiye'de yayılış gösteren Beta türlerinin içerdikleri varyasyonu karakterize etmek ve ıslahçılara belli özelliklere sahip materyal sunabilmek için Türkiye Beta koleksiyonu değerlendirilmiştir. Beta seksiyonuna ait 165 örnek 990 birey 23 karakter yönünden incelenmiştir. Gözlenen karakterler Ana Bileşen Analizi (ABA) kullanılarak değerlendirilmiş ve örnekler içerdikleri varyasyon yönünden gruplaridırılmıştır. Analiz sonuçları Türkiye 'de yayılış gösteren Beta cinsinin Beta seksiyonu örneklerinin geniş bir varyasyon sergilediğini göstermiştir.

Evaluation of beet (Beta L.) species distributed in Turkey: Beta section beta

Beta (Beet) species are the important genitorsfor cultivated beets. Turkey is being one of the centre of origin for beet, has important genetic base of beets belong to section Beta and section Corollinae. For this reason the Beta species of section Beta collected from Turkey has been characterised to transmit the material with its characteristics to the breeders. In this study 165 population sample with 990 individuals have been evaluated with 23 morphological characters. Principle Component Analysis (PCA) has been used to determine the diversity of the interpretation of the diversity. The result of Analysis exhibited broad morphological variation model section Beta found in Turkey.
