摘要:

以菊属8个野生种及变种、10个栽培种为亲本,设计了60个不同倍性菊花间的远缘杂交组合,采用常规压片法对所有杂交亲本及部分子代的倍性进行鉴定,以分析不同倍性菊花杂交的亲和性。结果表明,不同倍性的菊花栽培种与野生种间远缘杂交亲和性存在显著差异,四倍体 × 四倍体、四倍体 × 五倍体亲和指数最高,五倍体 × 二倍体、六倍体 × 二倍体亲和指数最低,但所有倍性差异的杂交组合均能结实、出苗。远缘杂交子代倍性变化十分明显,同倍性组合的子代倍性几乎与亲本一致,不同倍性的杂交组合子代倍性存在多样性。此外,通过使用低倍性菊属野生种间或低倍性野生种与栽培菊花杂交获得的中间种质作为桥梁亲本,能够在一定程度上克服远缘杂交不亲和或亲和性差的问题。

Abstract:

The 60 distant crossing combinations were designed by utilizing ten cultivars,eight wild species and variants of Chrysanthemum genus as the parents,and identified the ploidy of all parents and certain hybrids using the conventional tableting method,aiming to assess the crossing compatibility. The results indicated notable variations in compatibility of distant crossing among various ploidy cultivars and wild species in Chrysanthemums. The combinations of tetraploid × tetraploid and tetraploid × pentaploid exhibited the highest compatibility indexes,while pentaploid × diploid and hexaploidy × diploid had the lowest compatibility indexes. It was worth noting that all crossing combinations with differences in ploidy were able to set seeds and germinate. The ploidy variation of the hybrids was readily obvious,the hybrids resulting from crosses with the same ploidy exhibited similar ploidy to their respective parents,but there was diversity observed in the ploidy of hybrids resulting from different ploidy crossing combinations. In addition,the problems of distant crossing,which involve limited or inadequate compatibility,can be partially overcome by utilizing intermediate germplasms derived from crossing low-ploidy wild species or low-ploidy wild species with cultivars of chrysanthemum as bridging parents.

Key words: Chrysanthemum, wild species, distant crossing, crossing compatibility, ploidy, bridging parent
