The objective of this study was to evaluate the efficiency of factor analysis as one of the multivariate statistical methods into describing the mode of inheritance for lint quantity and quality in cotton. Seeds of six cotton cultivars along with 240 F6 recombinant inbred lines were planted to study in Hashem-Abad agriculture research station, Gorgan, Iran. The results of factor analysis showed that 83% of relevance among the parents was successfully explained by the six first factors. Based on the factor loadings, the three first factors were named "lint and seed production", "vegetative growth" and "lint quality". Biplot of factor scores showed that the highest "lint and seed production" and "vegetative growth" was belonged to cultivar Sahel, and there was no cultivar with high "lint and seed production" and low "vegetative growth". The highest score for factor "lint quality" was belonged to cultivar Number200; and Sahel was intermediate in this respect. The high potential of cultivar Sahel and its crosses proved that this cultivar is are still a very profitable pool containing genes controlling quantity and quality of lint in cotton for growing area in the North of Iran, particularly for Golestan province.
