Abstract

Abstract

Ten translocation homozygotes in safflower (Carthamus tinctorius L.) were established. The chromosomes involved in each interchange homozygote were identified through karyotype analysis by comparing the relative chromosome length (L%) and arm ratio (Pa-value) with that of the standard line ‘I.C. 11842’. The chromosomes interchanged were 6-8 (line 58), 1-3 (line 66), 3-12 (line 123), 3-10 (line 131), 3-6 (line 153), 4-6 (line 186), 4-8 (line 197), 3-8 (lines 208, 279) and 5-9 (line 290). The segment interchanges were not random, chromosome 3- (satellite-chromosome) was involved in 6 of the 10 translocations.
