Rice is the staple main food more than half the world's supply and in large part from Asia Continent suppler more than 80 percent of calories, and 75 percent protein, consumption people. One way of increasing production, using than techniques plant breeding, and from tool important is selection plant breeding. So advice from genetic diversity and classification of genotypes to scope select parents suitable course may be recombination new genes in necessary breeding projects. So 10 rice genotypes Iranians was used at the Research and Natural Resources kohgiloyeh and boyer -Ahmad. Analysis of variance showed that the between genotypes experimental from course traits chlorophyll, leaf area, leaf length, 100-grain weight, length and width grain and grain yield of a significant difference existed. Study the correlation showed that between grain yield and with chlorophyll, leaf area, length panicle relationship positive and is significant. Result Analysis of factor to method varimax method identifies five factors that together explained 86.75 percent of the total variation. Classification genotypes with using cluster analysis to the minimum variance method, Genotypes Euclidean distance 16 in the groping three different classes. With the results of this research can for be set to generate genotypes short, early high-yield from cluster of genotypes 1 and 2 as suitable parental crossing used.
