【 摘 要 】

20 varieties of sorghum were evaluated in a randomized complete block design with four replications in 2007 in the region of the Moghan. Analysis of variance of traits showed that there is a significant difference among the varieties except for stamen leaf area. Using cluster analysis of Ward's method based on standardized data and all traits the Iranian varieties and BISC-11 from India were ranked superior clusters. This grouping was confirmed by the detection function. In factor analysis, five factors were determined which explained 86.24% of the total variation. The first main factor explained 33.890 % of the total variation was introduced as a performance factor.
