The multichannel quantum defect theory (MQDT) has been applied to the dissociative recombination of NO{sup +} by collisions with slow electrons. The Rydberg states (superexcited states of the second kind) are fully incorporated by using the quantum defect functions. Five valence-type dissociative superexcited states of the first kind ({ital A}{prime} {sup 2}{Sigma}{sup +}, {ital I} {sup 2}{Sigma}{sup +}, {ital B} {sup 2}{Pi}, {ital L} {sup 2}{Pi}, {ital B}{prime} {sup 2}{Delta}) are all considered as the dissociation channels. Since the recently obtained quite reliable information on the superexcited states is employed in the calculation, the present results are considered to be the most accurate ones at this moment. Energy dependence of the cross sections shows intriguing resonance structures and varies from state to state, reflecting the relative dominance of the three basic important quantities: quantum defect function, electronic coupling, and Franck--Condon factor. The results are compared with other calculations and the available experiments.
