Abstract

Cabbage is a widely cultivated leafy vegetable, but head rot disease caused by the fungus Sclerotina sclerotiorum can seriously reduce its yield and quality. There are currently not any cabbage varieties that are completely immune to the disease, but its wild relative Brassica incana is very resistant. In this study, cabbage resistance was improved by backcrossing a highly resistant B. incana accession (C01) with a susceptible cabbage cultivar (F416). Although C01 lacks a leafy head formation, highly resistant plants appeared in the fourth backcrossing generation (BC4F1) that had a similar leafy head to F416. The individuals with strong resistance were purified by self-pollination. Inbred lines that maintained a relatively stable resistance at BC4F3 were developed and had significantly higher resistance to S. sclerotiorum than F416. In addition, hybrids created from a cross between of BC4F3 and E2 had higher resistances to S. sclerotiorum and similar agronomic characteristics to Xiyuan 4. The results demonstrated that new F416 lines that are resistant to S. sclerotiorum can be developed, and that these lines could be used to create new cabbage varieties with superior head rot resistance.

通过与 Brassica incana 杂交提高甘蓝对 Sclerotinia sclerotiorum 的抗性。
卷心菜是一种广泛种植的叶菜,但由真菌 Sclerotina sclerotiorum 引起的头腐病会严重降低卷心菜的产量和质量。目前还没有对该病完全免疫的卷心菜品种,但其野生近缘种 Brassica incana 的抗病性很强。在这项研究中,通过将高抗病性的 B. incana 品种(C01)与易感病的甘蓝栽培品种(F416)进行回交,提高了甘蓝的抗病性。虽然 C01 没有形成叶状头,但在第四代回交(BC4F1)中出现了高抗性植株,其叶状头与 F416 相似。抗性强的个体通过自花授粉得到纯化。培育出的近交系在 BC4F3 期保持了相对稳定的抗性,其对 S. sclerotiorum 的抗性明显高于 F416。此外,BC4F3和E2杂交产生的杂交种对硬粒病的抗性更高,农艺性状与西园4号相似。 研究结果表明,可以培育出抗硬粒病的F416新品系,并可利用这些品系培育出抗头腐病能力更强的甘蓝新品种:在线版本包含补充材料,可查阅 10.1007/s11032-024-01513-5。

期刊介绍: Molecular Breeding is an international journal publishing papers on applications of plant molecular biology, i.e., research most likely leading to practical applications. The practical applications might relate to the Developing as well as the industrialised World and have demonstrable benefits for the seed industry, farmers, processing industry, the environment and the consumer. All papers published should contribute to the understanding and progress of modern plant breeding, encompassing the scientific disciplines of molecular biology, biochemistry, genetics, physiology, pathology, plant breeding, and ecology among others. Molecular Breeding welcomes the following categories of papers: full papers, short communications, papers describing novel methods and review papers. All submission will be subject to peer review ensuring the highest possible scientific quality standards. Molecular Breeding core areas: Molecular Breeding will consider manuscripts describing contemporary methods of molecular genetics and genomic analysis, structural and functional genomics in crops, proteomics and metabolic profiling, abiotic stress and field evaluation of transgenic crops containing particular traits. Manuscripts on marker assisted breeding are also of major interest, in particular novel approaches and new results of marker assisted breeding, QTL cloning, integration of conventional and marker assisted breeding, and QTL studies in crop plants.
