The progeny in both T 1 and T 2 generation of the transgenic tomato containing TMV and CMV coat protein chimaeric gene had been analyzed through PCR,Southern blot,and the detection of resistance to viruses in green house and fields.The results showed that the segregation pattern of the TMV and CMV coat protein chimaeric gene,which has been integrated into one tomato plant,is accordant with Mendel's law of segregation,namely,the segregation ratio is 3∶1 in T 1 generation,and most of transgenic tomato line...
