Bitki Islahında Moleküler Belirteçlerin Kullanımı ve Gen Aktarımı

Öz

Tarımsal olarak önemli pek çok tür için moleküler belirteç haritaları oluşturulmuştur. Dünyada bu alanda fazla sayıda kaynak ve potansiyel var olmasına rağmen, henüz belirteç yardımlı seleksiyonla MAS gelişen tarım ürünleri için ticari ıslah programlarında beklenen düzeyde yarar sağlanamamaktadır. Bu derlemede, MAS kullanımındaki teknikler ile ilgili genel bilgilerin yanısıra bitki ıslahının hem temel genetik ilkeleri hem de klasik ıslah yöntemlerinden bahsedilmiştir. Ayrıca, bitki ıslahında karşılaşılan sorunlar biyoteknoloji ve genetik mühendislik yöntemleri dikkate alınarak ayrıntılı olarak incelenmiştir. Genetik ıslah aracı olarak belirteç yardımlı seleksiyon kullanımının potansiyel önemi değerlendirilirken bu tekniğin ekonomik maliyeti, yararları, potansiyel zararları da göz önünde bulundurulmalıdır

Application of the Molecular Marker and Gene Transfer in Plant Breeding

Abstract

Molecular marker maps have been constructed for the majority of agricultural important species. Despite the enormous potential and considerable resources invested in this field in the world, MAS has not yet delivered its expected benefits in commercial breeding programmes for crops development. This study provides an overview related to the techniques in using, MAS and the basic genetic principles of plant breeding and conventional breeding methods were discussed. In addition, the problems encountered of plant breeding by taking into account the biotechnology and genetic engineering methods were examined in detail. When evaluating the potential merits of applying MAS as a tool for genetic improvement, economic cost, benefits and potential hazards of this technique should be considered
