Studies on production capability of genet of wild compressed limpograss

10 production indexes of genet for 44 cases of wild limpograss from southwest district of China were compared. Significant difference was observed on the productivity of these limpograss. The results indicate that every production index of genet presents a great variation. And correlations between different indexes are observed. The variance analysis of yield indexes shows that stem/lamina is significantly-negatively correlated with the moisture of genet(r=-0.42563), and the moisture of lamina is positively correlated with the moisture of stem (r=0.69141), and the space distributing index is correlated with the stem/lamina (r=0.25985). According to the two main production indexes (first tiller number, second space distribution), the 44 cases of wild limpograss are classified into five types. Based on the productivity type, those resources can be studied and exploited to good purpose.
