Ster ility of Some Interspec if ic Hybr ids of D endran them a and Its Control

LI Xin-lei; CHEN Fa-di

Sterility of some interspecific hybrids ofDendranthem a and its controlmeasureswere studied. By studyingthe characters, pollen fertility and fecundity of self-cross of interspecific hybrid, itwas found that interspecific hybridof Dendranthem a possessed sterility, which characterized as some interspecific hybrids could not flower normally, thepollen fertility and the fecundity of self-crosswere low. The study on controlmeasures of sterility showed that colchicine treatment could overcome sterility of hybrid. The rate of fecundity of back cross of some hybrids exceeded 1. 0and the maximum was 6. 25. Embryo rescue after back cross of hybrid could solve the p roblem of low fecundity ef2fectively, and the rate of p lantlet formation varied from 3. 7% to 25. 0%.
