In the studies, possibilities in expanding their genetic variations through seed propagation were discussed. 1. Breeding of Zingiber mioga 1) Selection of selfed lines based on morphological characters One hundred-six selfed lines of the first generation of Z.mioga were raised during 1988 to 1989. From these lines, 29 selfed lines with different number of chromosomes (2n=49-60) were randomly selected together with a parental line and used for analyzing their morphological variations by multivariate analyzes.The analyzes showed that almost all of the selfed lines were smaller than the parent, but three strains among them produced more spikes than the parent. These results show that the breeding of Z.mioga can be improved by selecting desirable genotypes through seed propagation. 2) In vitro mass propagation of Zingiber mioga It was difficult to induce adventitious buds through the conventional shoot apex culture. Multiple shoots were however induced by vertically dividing shoot apex into two pieces and culturing them on agar medium containing 8 or 12 ppm BA.These multiple shoots were continuously propagated by dividing further into small pieces and culturing them on agar medium with the same BA concentrations. Many plantlets could be obtained by shaking the small pieces of multiple shoots in liquid medium with 1 ppm BA. 2.
