Abstract: 
Since rice, the staple food of more than half of the world's supply, the relationship between the numbers of different characteristics of this plant with yield, a randomized complete blocks experiment with three replicates and ten rice cultivars at the Research Center for Agriculture and Natural Resources Kohgiluyeh and Boyer was conducted in 2015. Eleven traits include: chlorophyll, length, width and surface of the leaf, stem, root and ear length, grain weight, grain length and grain yield were evaluated. The results of analysis of variance showed that there was significant difference between genotypes in chlorophyll properties, level and length of leaf, seed weight, length and width of grain and grain yield. Study of correlation showed that there was a significant positive correlation between seed yield and chlorophyll properties, leaf area, panicle length. The results of factor analysis by Varimax method identified five hidden factors that explained 86. 75% of the total variation. Classification of genotypes using cluster analysis using Ward's minimum variance, figures in Euclidean distance was 16 in 3 different classes classification. According to the results of this study it can be created to select the appropriate parental genotypes of dwarf and early high-yield, for contrast stresses abiotic and lodging from the intersection of the strange and urban genotypes of Ludab with Hassanarai.
