バレイショ近縁種に於ける種の分化に関する研究 2 : S.longipedicellatum × S.chacoenseの3倍性雑種に於ける染色体行動からみられた両親間の親和性

摘要

1) In this paper, the meiotic behaviour in the F_1 hybrid (2n=36) from the cross S. longipedicellatum (2n=48)×S. chacoense (2n=24) was described with special reference to the chromosome affinity between the parent species. 2) At the first metaphase in the
