To RPC, the fluidity was usually a key index, because it directly reflected the work-ability. The effect factors were complex, however, the quantity relation between the RPC fluidity and its effect factors could not be expressed with a uniform numeric formula.

The results showed that tiller number is mainly controlled by both the general genetic factor and the GE interaction factor (with 61.7﹪ of the general heritability and 17.2﹪ of the GE interaction heritability).A total number of 19 QTLs was detected to associate with tiller number. Of these, 9 and 6 QTLs were with single locus effects and digenic effects, respectively. The epistatic effect between QTL 1-8 and QTL 1-12 was suggested to be a major effect due to the contribution of 21.6﹪ in spring season.
