Abstract
The cross-compatibility between yellow-bract and red2bract p lants of M usella lasiocarpa was studied indifferent aspects: the pollen fertility, the fruiting characteristics, the germination of pollen and growth of pollentube. The results showed that the pollen viability could reach 95% while the germination was about 23%. Theinflorescenceswith bag developed no seed. The fruiting rate of open-pollinated treatment was 93% in-yellow bractp lants and 90% in red-bract p lants, while fruiting rate of hand-pollinated treatmentwas from 95% to 97%. It couldbe a concluded that the cross between yellow2bract and red2bract p lants ofM usella lasiocarpa was compatible.
