Abstract: The object was assess the efect of main agronomic traits of Glutinous Sorghum on yield. By the method of grey correlative degree analysis, the paper analyzed the correlative degree between yield and some important agronomic characters of Glutinous Sorghum in 2006—2007. The results showed that that the order of the correlative degree of main characters to yield was 1000-grain weight, heavy of per spike, growth duration, plant height and spike length. That is, the important character to yield influence in turn was:1000-grain weight> heavy of per spike> growth duration> plant height>spike length. Among them, affecting maximal main part is 1000-grain weight.The second is heavy of per spike. Growth duration over output is in the middle relatively. By contrast, the effect of plant height and spike length is relatively less.This provided an important theoretic basis for strategies in breeding and quality cultivating of Glutinous Sorghum.
