Figure 1From: Do transgenesis and marker-assisted backcross breeding produce substantially equivalent plants? - A comparative study of transgenic and backcross rice carrying bacterial blight resistant gene Xa21Bacterial blight resistance spectrum analysis of D62B, DXT and DXB. Nine Xoo strains from Philippine (P1-P10) were used to innoculate the rice leaves in the high tillering stage. The shorter the yellow portion on a leaf is, the higher plant resistance to Xoo infection. DXT: transgenic line with Xa21; DXB: MAB line with Xa21; D62B: the common parental line of DXT and DXB.Back to article page
