In the past few decades, a dozen grain size-related QTLs/genes have been cloned （Huang et al., 2013; Zuo and Li, 2014）. Pyramiding grain size QTLs to breed high-yielding and high-quality rice varieties has proved to be a great success. For example, by pyramiding the nonfunctional alleles gs3 and gw8 in line HJX74.展开更多
