A diverse set of molecular markers techniques have been developed over the last almost 40 years and used with success for breeding a number of major crops. These have been narrowed down to a few preferred DNA based marker types, and emphasis is now on adapting the technologies to a wide range of crop plants and trees. In this Special Issue, the strength of molecular breeding is revealed through research and review papers that use a combination of molecular markers with other classic breeding techniques to obtain quality improvement of the crop. The constant improvement and maintenance of quality by breeding is crucial and challenged by a changing climate and molecular markers can support the direct introgression of traits into elite breeding lines. All the papers in this Special Issue “Molecular genetics, Genomics, and Biotechnology in Crop Plant Breeding” have attracted significant attention, as can be witnessed by the graphs for each paper on the Journal’s homepage. It is the hope that it will encourage others to use these tools in developing an even wider range of crop plants and trees.

作物育种中的分子遗传学，基因组学和生物技术

在过去的近40年中，已经开发出多种多样的分子标记技术，并成功地用于育种许多主要农作物。这些已经缩小到一些基于DNA的优选标记类型，并且现在的重点是使技术适应各种农作物和树木。在本期特刊中，通过将分子标记与其他经典育种技术结合使用以提高农作物质量的研究和评论论文，揭示了分子育种的优势。通过育种来不断改善和维持质量至关重要，而且气候变化也给挑战带来了挑战，分子标记可以支持将性状直接渗入优良育种系。本期特刊“分子遗传学，基因组学，正如《期刊》首页上每篇论文的图表所证明的那样，“生物技术和农作物育种中的生物技术”已引起了极大的关注。希望它将鼓励其他人使用这些工具来开发更广泛的农作物和树木。
