Fig. 2From: Development and evaluation of improved lines with broad-spectrum resistance to rice blast using nine resistance genesIdentification of improved blast resistant lines with MAS. a PCR amplification of the marker LJ3–1 for blast resistance gene Pid3 in the BC2F2 population with the background of GZ63S. Lines 1, 2 and 3 are Digu (resistance homozygous), GZ63S (infected homozygous) and heterozygous (Digu/GZ63S), respectively. b Red arrows indicate susceptible parents GZ63S, yellow arrows show the resistant lines carrying target gene Pid3Back to article page
