以绿豆Berken/ACC41 F10重组近交系群体为作图群体,利用该群体已经构建的包含79个RFLP标记的分子连锁图谱,对北京和广西两个种植环境下的11个绿豆产量相关农艺性状进行QTL定位。结果表明,两个环境下共检测到产量相关性状QTL 63个(北京25个,广西38个),分布于除第13连锁群以外的12条连锁群。大部分QTL只在单一环境下被检测到,说明产量相关QTLs与环境之间存在明显的互作。两个环境均能检测到的QTL仅有6个,分别为控制荚长、百粒重、生育期的QTLs,这些能在不同生态环境发挥效应的QTLs对于绿豆分子标记辅助育种具有重要作用。研究还发现2个QTLs富集区域和若干成束分布的QTLs,它们可能是发掘通用QTL的候选位点。
Based on the molecular linkage map of 79 RFLP markers constructed by this population, 11 mung bean-related yield-related agronomic traits under two planting environments of Beijing and Guangxi were studied using the recombinant inbred line population of mung bean Berken / ACC41 F10 as the mapping population QTL mapping. The results showed that 63 QTLs for yield-related traits (25 in Beijing and 38 in Guangxi) were detected in two environments and distributed in 12 linkage groups except the 13th linkage group. Most QTLs were detected only in a single environment, indicating that there is a clear interaction between yield-related QTLs and the environment. Only six QTLs could be detected in the two environments, which were QTLs controlling the length of pod, the weight of 100 kernels and the growth period respectively. These QTLs, which can exert their effects in different ecological environments, play an important role in molecular marker-assisted breeding of mung bean. The study also found two QTLs enrichment regions and several QTLs distributed in bundles, which may be candidate sites for exploring common QTLs.
