| 摘 要： | 花生是我国重要的油料作物和经济作物,目前国内花生的产量远远不能满足消费者的所需,进一步提高花生单产是解决花生生产供不应求的重要途径。花生种子大小相关性状是花生的重要农艺性状,对提高花生单产至关重要。本文综述了植物种子大小的调控途径以及近年来花生分子标记、遗传图谱构建、种子大小相关性状QTL定位研究中取得的进展,探讨了目前花生种子大小相关性状研究中面临的挑战和机遇,对花生产量遗传改良进行了展望。

| Abstract: | Peanut is an important oil and economic crop in China.Currently,the domestic production of peanut remains far below the needs of consumers.Thus,further improving the yield per unit area is a crucial approach to meet the rising market demand.Seed size related traits are important agronomic traits in peanut,fundamentally contributing to improving yield per unit area.This review summarized the research progress on the regulatory pathways of seed size in plants,molecular markers,genetic linkage map construction,and QTL mapping of seed size related traits in peanut.We discussed the frontline challenges and opportunities for the coming researches of peanut seed related traits and the perspectives of yield improvement in peanut. |
