In nature, interspecific hybridization occurs frequently and can contribute to the production of new species or the introgression of beneficial adaptive features between species. It has great potential in agricultural systems to boost the process of targeted crop improvement. In the advent of genetically modified (GM) crops, it has a disadvantage that it involves the transgene escaping to unintended plants, which could result in non-specific weedy crops. Several crop species in the genus have close kinship: canola () is an ancestral hybrid of and and mustard species such as , , and share common genomes. Hence, intraspecific hybridization among the species is most common, especially between and . In general, interspecific hybrids cause numerous genetic and phenotypic changes in the parental lines. Consequently, their fitness and reproductive ability are also highly varied. In this review, we discuss the interspecific hybridization and reciprocal hybridization studies of and and their potential in the controlled environment. Further, we address the fate of transgenes (herbicide resistance) and their ability to transfer to their progenies or generations. This could help us to understand the environmental influence of interspecific hybrids and how to effectively manage their transgene escape in the future.
在自然界中，种间杂交经常发生，并可以促进新物种的产生或物种之间有益的适应性特征的渗透。它在农业系统中有很大的潜力，可以促进有针对性的作物改良过程。在转基因（GM）作物出现的情况下，它有一个缺点，即转基因逃逸到非预期的植物，这可能导致非特异性杂草作物。属中的几个作物物种有密切的亲缘关系：油菜（）是 和 的祖先杂种，芥菜物种如 、 和 共享共同的基因组。因此，属内种间杂交最常见，尤其是 和 之间。一般来说，种间杂种会在亲本系中引起许多遗传和表型变化。因此，它们的适应性和繁殖能力也有很大的差异。在这篇综述中，我们讨论了 和 及其在受控环境中的潜在的种间杂交和回交研究。此外，我们还探讨了转基因（抗除草剂）的命运及其向后代或后代转移的能力。这有助于我们了解种间杂种的环境影响，以及如何在未来有效地管理它们的转基因逃逸。
