Structural rearrangements in oat hybrids have been reported by several authors (Rajhathy and Thomas 1974, Singh and Kolb 1991). However, intercultivar chromosome interchanges in domestic oats have not been extensively investigated. Our objective in the present communication is to analyze the meiotic behavior of three hexaploid oat lines (Avena sativa L.) and three synthetic hybrids among them. This investiga­tion was initiated to study the cytogenetic structure of argentinian oat experimental breeding lines and its likely implicances in further breeding programs
