51 Effect of Breeding System on Phenotypic Traits and Essential Oil of Milk Thistle Silybum marianum L Genotypes Samaneh Shahidaval s shahidaval@gmail com September 21 2016 Department of Agronomy and Plant Breeding Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiMohamad Mahdi Majidi Majidi@cc iut ac irAbstractMilk thistle Silybum marianum is a member of Asteraceae family and is known as a medicinal plantwhich is effective in treatment of liver disease Due to climate and geographical conditions Iran isextensive habitat of this plant In order to design a breeding program it is necessary to increace theknowledge genetic of variation and reproductive system of this plants This study was conducted toevaluate the effect of reproductive system self pollination and cross pollination on phenotypic traits silymarin and oil of milk thistle genotypes under normal and drought stress conditions during 2014 2015at the research farm of Isfahan University of Technology IUT For this purpose 22 genotypes resultedfrom self pollination S along with 22 of corresponding genotypes which resulted from cross pollination OP were investigated as combined analysis moisture environments in randomized complete blockdesign Results showed that genotypes had high variation in terms of evaluated traits in both populations S and OP Overall mandatory selfing caused reduction in plant performance Under drought stressenvironment cross pollination caused the significant increase of seed yield and self pollination increasedthousand seed weight Self pollination increased thousand seed weight and decreased percentage ofsilymarin The increase of thousand seed weight can be due to decrease of number of seed per capitol which resulted from self pollination In this study those genotypes which were related to stress maternalenvironment were superior in terms of percentage of oil and seed yield under both self and crosspollination In general genotype 7 from Mahshahr had the most average in terms of most traits underboth self and cross pollination conditions As the negative effects of inbreeding were low in thisgenotype it can be used in the future breeding programs for developing inbred lines Keywords Silymarin Reproductive system Milk thistle Morphological traits
