摘 要 ：1989年,进行了谷子(Setaria italica)Ch4n×法氏狗尾草位(S.fabeiii)的远缘杂交和杂种胚培养。共接种已授粉子房264个,得到22株苗,仅11株成活。试管苗经继代培养和繁殖,得到了大量的小植株,移栽成活并发育到成熟。经形态学和细胞学鉴定,其中有两个株系是杂种,杂种F_1的染色体数为2n=4x=36,花粉母细胞在减数分裂中期Ⅰ染色体配

Abstract:Immature embryo culture of a wide cross, Setaria italica (Ch 4n)/S. faberii, was carried outin 1989. 22 seedlings were obtained from 264 pollinated ovaries cultured on modified MS me-dium with or without growth regulators, but only 11 survived after the second subculture.They were propagated into nu
