Abstract: In order to screen out mulberry varieties with strong drought resistance and ideal sericulture achievement in Guizhou, 8 drought-resistant mulberry varieties （ZL10, HP11, HP8, DJ2, THS, HCS, GSY12 and DJ6） were screened by drought tolerance coefficient and sericulture traits, and the significance analysis of their main economic traits were conducted. The results showed that the mulberry cocoon yield of THS was significantly higher than that of the control （Husang 32）, and the economic characters were prominent in production, and has high application value in the current drought-tolerant mulberry materials. There is no significant difference between the mulberry cocoon yield of HCS, DJ2 and DJ6 and the control, and it has application value in the current drought-tolerant mulberry materials. The mulberry cocoon yield of ZL10, HP8, HP11 and GSY12 was significantly lower than the control, and they have no advantage in economic characters and thus have no application value.

Key words: drought tolerant materials, economic traits, mulberry tree, Guizhou province
