Many of the seeds I purchase are Ed Hume seeds grown particularly for the Northwest. I have found good tips on his site http://www.humeseeds.com/index.htm
WSU Extension - Tomato Types for Northwest
We need to select short-season varieties that do not require a lot of heat to ripen. When looking at the seed packet or catalog, read the "days to maturity" and choose tomatoes with the shortest number of days. The number usually will be all wrong for our climate, since ripening will happen much more slowly here. Still, they are a guide to help you choose a variety that stands a chance of ripening here.
Another consideration is whether the variety is open-pollinated or a hybrid. A hybrid seed comes from a cross between two different varieties, made to obtain a certain set of characteristics. (The seed from a hybrid has a different mix of the parent plants' genes and usually produces less desirable plants.) An open-pollinated variety holds on to the parents characteristics generation after generation. This is important, if you want to save seed.
Also, tomatoes have either a determinant or an indeterminate growth habit. Determinate tomatoes tend to have compact plants and the fruit ripens more closely together. Indeterminate plants continue to grow and the fruits keep setting until frost.
