Description
A source of male sterility in orchardgrass (Dactylis glomerata L.) was selected. These plants were classified into four types; male sterile (S2), partially male sterile (S1), partially fertile (S0) and normal (N). Evidence of the effects of S ( sterilizing) cytoplasm on expression of male sterility was suggested by reciprocal differences in the crosses of S0 x N. Two models were assumed for genotypes of male sterility and data obtained from progeny test of the experimental crosses were applied to the models. Expression of male sterility appeared to be induced mainly by an interaction of S cytoplasm and a dominant gene. Expected genotypes were explained as follows: S2= quadruplex(AAAA), triplex(AAAa) and duplex(AAaa), and N = nulliplex( aaaa). However, we failed to determine exactly the action of simplex( Aaaa) which expressed S2, S1, S0 and N types variously according to individuals.
