Karyotype Analysis of Native Safflower Carthamus tinctorius L. Lines

Abstract

01.-A-95, 308-A-95 and N-10A-95 lines with Native-8 variety as being candidates for the variety developed form native and foreign safflower varietes which were grown in Field Plants Department of Faculty of Agricuiture of Ankara University in 1995 were used in this investigation. The seeds belonging to these materials were germinated in Genetics Laboratory of Department of Biology of Gazi University Educational Faculty and chromosomes were investigated by root tips squash method. The chromosome number of the investigated lines and variety was found as 2n=24 chromosomes were named and idiogram was made by calculating the arm-indexes, propotional heights and centromer indexes of chromosomes.

Yerli Aspir Carthamus tinctorius L. Hatları nda Karyotip Analizi

Abstract

Bu araşt ı rmada, Ankara Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölömünde yerli ve yabanc ı °dinli Aspir çeşitlerinden geliştirilmiş çeşide aday 01.-A-95, 308-A-95 ve N-10-A-95 hatlar ı ile Yerli- 8 çeşidinin 1995 yı l ı materyalleri kullan ı lmışt ı r. Bu materyallere ait tohumlar 1996 y ı l ı nda Gazi Üniversitesi E ğitim Fakültesi Biyoloji Bölümü Genetik labaroratuvar ı nda çimlendirilmiş ve kök uçlar ı nda ezme metoduyla kromozomlar incelenmi ştir. Incelenen hatlar ı n ve çeşidin kromozom sayı sı n ı n 2n=24 olduğu tespit edilmiştir. Kromozom kol indeksleri, oransal boylar ı , sentromer indeksler' hesaplanarak kromozomlar isimlendirilmi ş ve idiogram yap ı lmışt ı r.
