[en] Within the framework of the quark model the products of inclusive hadron interactions are considered. Relative meson yield both with L=0 and L=1 with account of 2J+1 spin multipliers and known probabilities of resonance decay is calculated. The production probability ratio of the S to P wave states is introduced as a free parameter. From the comparison with the experimental data the ratio is established to have an order of 0.3-0.4. The data on the g⁰ inclusive production show that the number of D-wave states(L=2) is not small as well. The presence of the states with L=1 has small effect on the correlations between the probabilities to detect vector mesons (Jsup(P)=1sup(-)), but makes some of them absent in the case with L=0, different from zero. The discrepancy between theory and practiye looks like a systematic undervaluing of the number of pseudoscalar particles by about 25%. The greatest divergence with the experiment is observed for eta'/eta and rho⁰/π^- ratios
