Abstract

Factor analysis is a general method for analyzing data and is used to investigate relationships among variables without distinguishing some as independent and others as dependent ones. Phenotypic and genetic factor analyses of 13 traits were carried out for eight genotypes of SPRING SAFFLOWER (Carthamus tinctorius L.) under stress and non-stress IRRIGATION REGIMES. Each experiment was conducted as a randomized complete block design with three replications. Genetic correlation matrix was used to obtain a genetic factor matrix to recognize seed yield-related characters and their associations with seed yield to determine the best criterion for identification of high-yielding genotypes under stress and nonstress IRRIGATION REGIMES. Results indicated that selection based on biological yield, 1000-seedweight and plant capitula weight, may be desirable for high-yielding genotypes under stress conditions, whereas, selection based on biological yield, number of capitula/plant, plant capitula weight, capitula harvest index and harvest index, may be more efficient for identifying high-yield genotypes under non-stress conditions. Furthermore, biological yield and plant capitula weight may be suitable for screening of high yield genotypes under both IRRIGATION REGIMES.
