The first maternal inheritance of chlorina character in a barley strain Coast V was reported by Robertson (1937). During the course of allelism tests of more than 100 chlorina-type mutants accumulated in the Genetic Stock Center at Fort Collins, Colorado, the authors have found two more cases of maternal inheritance of chlorina characters.
Trebi 67-8043A has a bright yellow character at the early seedling stage. Later the leaves change color to green from the leaf tip towards the base.
Trebi VIII has similar characteristics to Trebi 67-8043A mentioned above.
If these chlorena mutants are used as female parents in crosses with green
plants as the male parent, the F1 plants are chlorina. Whereas the F1 hybrids
from the reciprocal crosses (green x chlorina) were all green. The results
indicate that the two chlorina mutants are maternally inherited. These
two mutants differ in appearance from the Coast V mutants.
