Abstract

Bu çalışmada 31 Aspir (Carthamus tinctorius L.) çeşidine ait
kromozom sayıları ve karyomorfolojileri araştırılmıştır. Kromozom
sayımları, Carthamus'un aynı temel
kromozom sayılarına sahip olduğunu gösteren daha önceki raporları
doğrulamıştır.  Elde edilen sonuçlara
göre, kromozom sayıları tüm çeşitler için 2n = 24, x = 12 olarak tanımlanmış ve
aynı zamanda tümünün diploid kromozom sayısına sahip oldukları bulunmuştur. Karyotiplerde
metasentrik ve submetasentrik olan kromozomların baskın olduğu tespit
edilmiştir. Tüm çeşitleri karyolojik açıdan değerlendirmek ve C. tinctorius
çeşitleri arasındaki kromozomal değişikliklerini aydınlatmak için beş adet
kantitatif asimetri indeksi kullanılmıştır. Tüm karyotip analizleri ilk kez bu
raporda KAMERAM programı ile tanımlanmıştır. Çalışmada elde edilen bulguların Carthamus türünün genetik ve ıslah
çalışmalarına katkıda bulunmasını umuyoruz

Karyotype analysis of some lines and varieties belonging to Carthamus tinctorius L. species

Abstract

In this paper, karyology of
thirty one accessions of Safflower (Carthamus tinctorius L.) were
investigated in terms of their chromosome numbers and karyomorphology. The
chromosomal counts confirmed the results of previous reports, that the Carthamus has same basic chromosome
numbers. According to our results discussed all accessions of chromosome
numbers have been identified 2n = 24, x=12 and also all have the diploid number
of chromosomes. We found predominance of chromosomes being metacentric and
sub-metacentric. Five quantitative asymmetry indices were used to evaluate our
karyological results in all species and elucidate the chromosomal alterations
of Carthamus tinctorius accessions.
All karyotyping analyses were described for the first time in this report via
KAMERAM programme. We hope that these findings would be contributed for Carthamus genetic and breeding studies.
