Abstract: Let $ A$ be a commutative ring with identity. The main result states conditions that ensure the finiteness of prime ideals in a coherent ring $ A$ of global dimension two. Precisely, any ideal containing two noncomparable prime ideals is finitely generated. As a corollary it follows that a Krull domain of global dimension two is noetherian. Another corollary is that if $ A$ is not semihereditary it contains a finitely generated maximal ideal.
