Southern blotting produced only a strong signal in the control but nothing in the test DNA. Did my transformation fail?

I transformed some plants, grown from initial stages till rooting on 100- 50 mg kanamycin media. After extracting DNA I did PCR using Gene specific primers and got clear sharp bands of desired...
