I am trying out Hawaiian Pineapple this year. It is a beefsteak type tomato, which has been a good size for slicing. Mine tend to have cracks, as you can see. It is flavorful and a good producer this year in my garden, with some tendency to have disease (fusillarium or verticillium) but not terrible. And how many tomatoes can you grow that are 'school bus yellow?'
This one is a favorite - Lemon Boy- I've grown this variety for several years, now. It is consistent and produces a nice sized fruit.
Both yellows are yum-tastic, and I'll grow them again next year, I think.
