摘要

Citropsis schweinfurthii (Engl.)Swing. & M. Kell. species, native to Africa, are considered to be surviving remote ancestors of Citrus. In a previous study, we reported the first-time production through an embryo culture of sexual intergeneric hybrids between the Citrus cultivar ' Nanpu' tangor and C. schweinfurthii. CMA chromosome banding for both parents and progenies was conducted to obtain cytogenetic information. The karyotype composition of C. schweinfurthii was very simple (14D + 4E) , while that of ' Nanpu' tangor had other, additional chromosome types (1A + 4C + 5D + 8E). Two progenies with C. schweinfurthii as the maternal parent showed 1A + 1C + 11D +5E both, suggesting that each one of the type A and C chromosomes were inherited from ' Nanpu' tangor. Thus, hybridism was proven at the chromosome level. However, the growth of these progenies showed serious weaknesses under greenhouse conditions. Interestingly, the vigor of the progenies with ' Nanpu' tangor as the maternal parent was obviously less than those with C. schweinfurthii as the maternal parent. This phenomenon might result from the interaction between the nucleus and cytoplasm. When these intergeneric hybrid progenies were grafted onto C. schweinfurthii, they showed vigorous growth.

Kell。物种，原产于非洲，被认为是幸存的柑橘的远程祖先。在以前的一项研究中，我们通过柑橘品种“Nanpu'angor和C.Schweinfurthii之间的性仲太基杂交种胚胎培养来报告第一次生产。对父母和后代的CMA染色体带进行了细胞遗传学信息。 C.Schweinfurthii的核型组合物非常简单（14d + 4e），而'nanpu'橘子的亚蜜具有其他染色体类型（1a + 4c + 5d + 8e）。作为母体母体的两种与C. schweinfurthii的后代显示1a + 1c + 11d + 5e两者，表明A和C染色体中的每种类型是从'Nanpu'andor遗传的。因此，在染色体水平中证明了杂交。然而，这些后代的生长在温室条件下表现出严重的弱点。有趣的是，随着母体父母的“Nanpu”弱者的生命力明显低于C.Schweinfurthii作为母亲父母的活力。这种现象可能来自细胞核和细胞质之间的相互作用。当将这些羟基杂交后代嫁接到C.Schweinfurthii上时，它们表现出剧烈的生长。
