Abstract

In the selfed progeny of a spontaneously produced triploid interchange heterozygote four different double trisomic plants were observed. In all the plants the frequency of alternate orientation of multivalents was lower compared to their respective types in the sib single trisomic plants. The frequency of alternate co-orientation of the interchange complex in these trisomics was also reduced compared to that of parental euploid disomic interchange heterozygotes. It is suggested that the presence of extra chromosomes influences the orientation behaviour of higher associations in different trisomics.
