Maybe my favorite tomato! Extremely profuse and disease resistant in my garden last year. The perfect slicing tomato. Very firm and meaty, with out-of-this-world flavor!

Big, productive plant made a lot of complex and great tasting, light orange tomatoes. The plant seemed to ripen a little slower than many others in my yard, but the long term payoff is good. This plant was still cranking out tomatoes in the late Summer heat, which is usually too much for many varieties to handle in my particular yard.

Grew KB in 2006 and KBX in 2007. Found KBX to be a more productive, disease resistant plant with the same excellent taste as it's RL brother. Both were grown in 7 Gallon containers.

Potato leaf variant of Kellogg's Breakfast. Taste and appearance of fruits are identical. Very good flavor.
