葫芦科作物重要性状基因定位研究进展

Research Progress in Gene Mapping of Important Characters in Cucurbit Cropsa

瓜类是重要的蔬菜、水果类作物,随着生活水平的不断提高,人们更加注重农产品的品质和产量,因此进一步提高瓜类产品的品质和产量,满足人们对优质农产品的需求成为当前科学研究的重要任务之一。优良品种选育是进一步提高葫芦科蔬菜作物品质和产量的有效方法,分子育种是加速育种进程的重要手段,而基因定位是现代分子育种研究的基础。本文综述了主要葫芦科作物重要性状基因定位的策略、方法以及初步定位和精细定位工作的研究进展,为相关作物的基因精细定位、基因克隆研究提供参考依据,并对今后的葫芦科作物精细定位技术提出了展望。

Melons are important vegetable and fruit crops. With the improvement of living standards, people pay more attention to the quality and output of agricultural products. Therefore, it is one of the most fundamental tasks of scientific research to further improve the quality and output of cncurbit products to meet the needs of people for high quality agricultural products. The most practical and effective method is to fine varieties breeding. Molecular breeding is an important means to speed up the breeding process, and gene mapping is the basis of modern molecular breeding research. This paper summarizes the strategies and methods of gene mapping of important characters of cucurbit crops and the research progress of gen initial location and fine mapping, which would provide reference for gene fine mapping of related crops and gene cloning and the prospect of fine location technique for cucurbit crops.
