Figure 1. Agarose gel analysis of PCR products of reaction performed with the primers for rapeseed specific internal target phosphoenolpiruvate carboxylase gene. The amplificability of the DNA extracted by CTAB method was confirmed through visualization of amplicons 248 bp. In line 1 molecular weight marker; line 2 blank; line 3 soybean (negative control); line 4 rapeseed (positive control); lines 5-14 rapeseed samples.
