Abstract：
Two relations for the production weights of baryons including all their excited states are derived based on the properties of hadronization in the stochastic quark combination scheme. The so-called Mspin suppression" and why singlet baryons have high production rates are naturally explained. Approaches and conditions to extract the production percentages of excited baryons are discussed.
