Abstract
Eighteen ginger strains were collected mainly from Asian countries from 1985 through 1989 to investigate their pollen fertility and germinability. The pollen fertility test was performed in mid-October 1990, and that for pollen germinability was conducted during November 1990. All strains displayed low pollen fertility; three strains had pollen fertility ranging from 20.9% to 21.4%, seven from 10.6% to 19.0%, and eight from 0.9% to 7.4%. In the pollen germinability test, 14 strains used had very low germination rates; four had germination rates ranging from 0.15% to 0.22%, three from 0.06% to 0.10%, and seven from 0.00% to 0.02%.
