摘要
本文整理分析了我国花生单产、种植面积与种植结构的统计数据,综述了国内外花生(百)果质量、单株果数和出仁率的遗传定位文献,为高产育种提供理论依据和实用工具。花生(百)果质量的QTL分布于13个热点染色体(A3、A4、A5、A6、A7、A8、B3、B5、B6、B7、B8、B9和B10),共定位出59个主效QTL。强候选基因有3个:Arahy.3R9A5K、Aradu.K0L5G和AhRUVBL2(Arahy.TSR8I7)。开发了3个分子标记,确定了3个显著关联的SNP分子标记。花生单株果数QTL所在的染色体有13个,分别为A2、A4、A5、A6、A7、A9、A10、B3、B4、B5、B6、B7和B8,其中A5、A9和B8为热点染色体。共有22个QTL,其中6个为主效QTL,候选基因为AhMYB51(Arahy.04JNDX)。花生出仁率的QTL的热点染色体有11个,分别为A4、A5、A7、A8、A9、B1、B3、B4、B5、B6和B10,主效QTL有24个。强候选基因有4个:Aradu.A5UR9、Araip.J1S7B、Araip.Y03J3和Araip.X1ALQ,开发了4个分子标记,确定出10个显著关联的SNP分子标记。这些研究为花生高产品种的精准选育提供了关键靶点和高效工具,有助于我国花生产业提质增效。
In this paper,the statistical data of per unit area yield,cultivated area and planting structure of peanuts in China were analyzed,the literature on genetic localization of(hundred)pods mass,number of pods per plant and shelling percentage were reviewed,which provided theoretical basis and practical tools for high yield breeding.For(hundred)pods mass,QTLs were identified on 13 hotspots chromosomes(A3,A4,A5,A6,A7,A8,B3,B5,B6,B7,B8,B9,and B10),and 59 major-effect QTLs were identified.Three strong candidate genes were pinpointed as Arahy.3R9A5K,Aradu.K0L5G,and AhRUVBL2(Arahy.TSR8I7).Three molecular markers were developed and three significantly associated SNP molecular markers were identified.Regarding number of pods per plant,QTLs were distributed across 13 chromosomes(A2,A4,A5,A6,A7,A9,A10,B3,B4,B5,B6,B7 and B8),in which A5,A9 and B8 were hotspots.A total of 22 QTLs were identified,including 6 major-effect QTLs.Shelling percentage QTLs clustered on 11 chromosomes(A4,A5,A7,A8,A9,B1,B3,B4,B5,B6,and B10),with 24 major-effect QTLs were detected.4 candidate genes were highlighted as Aradu.A5UR9,Araip.J1S7B,Araip.YQ3J3,and Araip.XIALQ.4molecular markers were developed,and 10 significantly associated SNP molecular markers were identified.These findings established critical targets and efficient tools for precise high-yield peanut breeding,thereby beneficial to enhance the quality and efficiency of peanut industry.
