We study the productions of p-wave mesons K{sub 0}*(1430), K{sub 1}(1270), and K{sub 1}(1400) in B decays. By the generalized factorization approach, we find that the branching ratios of B{yields}K{sub 0}*(1430){phi} are similar to those of B{yields}K{phi} while the branching ratios of B{yields}K{sub 1}(1270){phi} and B{yields}K{sub 1}(1400){phi} are O(10{sup -5}) and O(10{sup -6}), respectively. In terms of the observation of B{yields}K{sub 1}(1270){gamma} by BELLE, we can remove the sign ambiguity in the mixing angle for physical states K{sub 1}(1270) and K{sub 1}(1400). In addition, we analyze annihilation contributions in the decays B{yields}K{sub 1}{phi} and we conclude that they could be neglected.
