By using α-amylase isozymes as markers for chromosomes of homoeologous groups 6 and 7, we analyzed the segregation of chromosome constitution in the progenies from crosses between double-ditelosomic or ditelosomic lines of hexaploid wheat cultivar `Chinese Spring (CS) as the female parent and double-monosomic F1 hybrids of CS × wheat-barley substitution lines for barley chromosomes 6H or 7H. From this analysis we estimated the transmission rate via pollen of barley chromosomes 6H and 7H in the double-monosomics and evaluated the compensating ability between barley and wheat chromosomes in homoeologous groups 6 and 7. The results indicated that both 6H and 7H showed their highest compensating ability for their respective homoeologous wheat chromosomes 6A (37.5% transmission rate) and 7A (39.4%), intermediate for 6D (34.1%) and 7D (29.6%), and lowest for 6B (26.6%) and 7B (22.6%) chromosomes.
