栽培高粱[Sorghum bicolor(L.)Moench race bicolor,de Wet,2n=20]与约翰逊草[Sorghum haleponse(L.)Pers.,2n=40]之间的染色体组的亲缘关系,以往曾是广泛研究的课题。然而,这些研究都未涉及这两个物种的染色体倍数水平和染鱼体组的数目。本文检验了先前在这两个物种的染色体配对研究中所提出的亲本种、具30个染色体杂种、具40个染色体杂种和具60个染色体双多倍体等4种主要染色体组 The genetic relationship between cultivated sorghum [Sorghum bicolor (L.) Moench race bicolor, de Wet, 2n = 20] and the genome of Sorghum haleponse (L.) Pers., 2n = 40 has been widespread Research topic However, none of these studies addressed the chromosomal fold and the number of fish-infected groups in both species. In this paper, we examined the parental species previously proposed in the chromosome pairing studies of these two species, with 30 chromosome hybrids, 40 chromosomal hybrids, and 60 chromosomal duplications, including 4 major chromosomal groups
