Özet:

 In this study, 0.1 colchicine solution at different times 4, 8 and 12 hours was applied to the seeds of two-row Hordeum vulgare conv. distichon Ünver and six-row Hordeum vulgare conv. hexastichonAltıkat barley varieties that started to germinate. The effects of changes in genetic structure with colchicine application on some agricultural characteristics were investigated. The study was carried out in two processes as field and laboratory conditions. As colchicine application time increased, germination rate decreased significantly in both laboratory and field conditions. However, the reduction in emergence rate was greater in both cultivars under field conditions. Variation in plant height, spike length, number of spikelets per spike, spike density, number of grains per spike and grain weight were determined in living plants Co after colchicine application. In terms of the examined characteristics, plants that exceeded the control plants at a significant level were determined. Selecting and transferring these plants to the next generations may provide the opportunity to obtain new varieties for different purposes.

 Bu araştırmada çimlenmeye başlayan iki sıralı Hordeum vulgare conv. distichon Ünver ve altı sıralı Hordeum vulgare conv. hexastichon Altıkat arpa çeşitlerinin tohumlarına  0.1lik kolçisin solüsyonu farklı sürelerde 4, 8 ve 12 saat uygulanmıştır. Kolçisin uygulaması ile genetik yapıda meydana gelen değişimlerin bazı tarımsal özelliklere etkisi incelenmiştir. Çalışma tarla ve laboratuvar koşulları olmak üzere iki aşamalı yürütülmüştür. Kolçisin uygulama süresi uzadıkça hem laboratuvar hem de tarla koşullarında çimlenme oranı önemli seviyede azalmıştır. Ancak tarla koşullarında her iki çeşitte de çıkış oranındaki azalma daha fazla olmuştur. Kolçisin uygulamasından sonra yaşayan bitkilerde Co bitki boyu, başak uzunluğu, başakta başakçık sayısı, başak sıklığı, başakta tane sayısı ve tane ağırlığı yönünden varyasyon belirlenmiştir. İncelenen özellikler yönünden kontrol bitkileri önemli seviyede geçen bitkiler tespit edilmiştir. Bu bitkilerin seçilerek ileri generasyonlara aktarılması, farklı amaçlar için yeni çeşitlerin elde edilmesine imkân sağlayabilir.
