For investigation quantitative and qualitative properties of different lines and cultivars of rapeseed, 19 selected lines from advanced inbreeding progenies, and Zarfam variety (as check), totally 20 lines and varieties, were evaluated in a randomized complete block design with three replications at the experimental field of Seed and Plant Improvement Institute in Karaj, during 2005-6. Morphological traits and 1000 grain weight, biomass, grain and oil yield, profile of fatty acids and glucosinolate content, were recorded in a cropping season. Factor analysis based on principle component was used for describing the relationship among different traits. The results showed that four factors could explain 67.5 percent of total variance of data. The portions of each factor were 21.9, 18.5, 14.6 and 12.5 percent, respectively. These factors were called phenological parameters, yield components, oil and grain yield and silique properties, respectively. Second and third factors had an important role in increasing of oil and grain yield, and the efforts for improving these factors can be a solution for increasing of oil and grain yield. Also, for evaluating the profile of fatty acids and glucosinolate content of lines, factor analysis were performed and the results showed that four factors could be enough for explanation of the variance of data. Scatter plot based on these factors showed that Consul and H. 42 lines were suitable in comparison with other lines, because of the high oil, grain yield and desirable profile of fatty acids and glucosinolate content.
