Primary trisomic analysis of Zb c for zebra Colorado gene . Mutants were of original Utah T41 stock. However, for the sake of convenience, it was treated as a recessive.
Heterozygotes show a general pale yellow-green color.
F2 segregation was observed in a diploid control from selfed diploid F1 hybrids and in populations from selfed trisomic F1 hybrids. Normal green plants and heterozygotes were classified as normal. Further studies are underway to associate this gene with remaining five primary trisomic types. The establishment of a trisomic series in a two-rowed cultivated variety of barley.
