本实验室前期利用90K芯片,在豆麦/石4185构建的RIL群体中,鉴定到11个粒重QTL位点,其中QTKW.caas-4BS横跨Rht-B1位点,在全部6个环境中均稳定存在,解释12.1–45.6%的表型变异,但是与株高关系不大。为进一步解析QTKW.caas-4BS遗传调控机制,通过基因组挖掘和Wheat660K芯片,利用RIL群体在该区间内加密了8个标记,将QT...
Wheat, an important cereal crop globally, faces major challenges due to increasing global population and changing climates. The production and productivity are challenged by several biotic and abiotic stresses. There is also a pressing demand to enhance grain yield and quality/nutri...
