I read more from a great plant pathology book by George Agrios to find out if a plant virus can be spread through saving seeds.

Seeds can and do transmit viruses, but TYLCV is so virulent that virtually no fruit or seed make it to maturity so it is not likely to come from infected seed.

In Isreal, TYLCV is so bad tomatoes are grown only under a fine mesh fabric and sprayed to keep the whitefly vector out. There are also many weeds that TYCLV can overwinter on and doesn't kill that whiteflies visit in the spring.
