'Better Boy' Tomato: Hybrid by Definition, Not a Separate Type

What's the difference between a 'Better Boy' tomato plant and a 'Hybrid Better Boy'?

They're the Same Plant

'Better Boy' is a hybrid, developed in 1942 by Dr. Oved Shifriss at W. Atlee Burpee & Co. It's bushy, vigorous, disease-resistant, with parentage kept as a trade secret. The term "Hybrid Better Boy" is redundant—all 'Better Boy' tomatoes are hybrids.
