Comparative Karyotype Analyses in Some F7 Generation Pea (Pisum Sativum L.) Lines and Their Parents

Year 2006, Volume: 20 Issue: 38, 150 - 158, 25.04.2006

Abstract

This research was carried out to determine karyotypes of the nine pea lines consisting of four parental lines and five hy-brid progenies at F7 generation. Chromosome numbers, lengths, branch indices, relative lengths and chromosome types were determined. The chromosome numbers of all the pea lines were 2n=14. Chromosome lengths were between 2.80 m-4.95 m while branch indices and relative length were between 0.51-0.84 and 5.47-9.37, respectively. Types of chromosomes have been found to be metacentric and submetacentric. Not only satellites were found on all the lines examined, but also a pair of chro-mosomes with satellite on four hybrid and two parental lines. In addition, two pairs of chromosomes with satellite in one hybrid line and two parental lines were observed. The chromosome lengths of hybrid progenies were generally longer than the chromosomes lengths of parental lines.

F7 Generasyonundaki Bazı Bezelye (Pisum Sativum L.) Hatlarında Karyotip Analizi ve Ebeveynlerle Karşılaştırmalar

Year 2006, Volume: 20 Issue: 38, 150 - 158, 25.04.2006

Abstract

Bu araştırma, 4’ü ebeveyn, 5’i F7 generasyonunda bulunan 9 adet bezelye hattının karyotipini belirlemek amacıyla yapıl-mıştır. Araştırmada bezelyelerin kromozom sayısı, kromozom boyları, kol indeksleri, oransal boyları ve kromozom tipleri belirlenmiştir. Bezelye hatlarının tamamının kromozom sayısı 2n=14 olarak tespit edilmiştir. Kromozom boyları 2.80 m–4.95 m, kol indeksleri 0.51-0.84, oransal boyları 5.47-9.37 arasında bulunmuştur. Kromozom tipleri metasentrik ve submetasent-rik olarak tespit edilmiştir. İncelenen tüm hatlarda satelit bulunmakla beraber 4 melez, 2 ebeveyn hatta birer çift satelitli kro-mozom ve 1 melez, 2 ebeveyn hatta ikişer çift satelitli kromozom gözlenmiştir. Melez yavruların kromozom boylarının genellikle ebeveynlerden daha uzun olduğu tespit edilmiştir.
