Most agronomic traits such as yield, quality and stress-tolerance of rice are quantitativetraits. Dissection of the genetic basis for these traits is difficult, because they are controlledby multi-genes that are affected by environmental factors, Rice improvement and dissectionof complex traits require germplasm diversity and understanding the genetic basis of thesetraits. With the development of genomics and biostatistics software and applications ofmolecular markers in crop breeding, association an...
