Safflower is a self-pollinating oilseed crop and has been cultivated since antiquity in the Middle East. become minor crop, to increase its cultivation it necessary characterize introduce new germplasm. Thirty-eight safflower cultivars breeding lines from different countries have screened with 8 AFLP primer combinations assess genetic diversity relationships among these genotypes. primers produ...

seed rot caused by pythium ultimum is an important disease of safflower in iran and other countries. therefore, finding the genetic sources of resistance and releasing of resistant cultivar is considered as important objective by safflower breeders. this disease will spread when air humidity and the moisture in the soil are sufficiently prepared and this situation occurs exactly in the time of ...

damage of the pathogens is one of the main limitations for cultivating and production of safflower. this study was performed to investigate reaction of safflower genotypes to pythium ultimum during 2009 and 2010 under field conditions. the study was done in two parts, selection and evaluation of parents (part 1; 2009) and evaluation of the progenies (part2; 2010). in the first year, the experim...

One of the major field constraints to seed production in safflower has proven tobe soil born pathogens, Phytophthora drechsleri and Pythium ultimum. In order toevaluate the efficiency of a field-laboratory selection method to improve resistanceof safflower against soil born pathogens, Ph. drechsleri and P. ultimum, a two-yearinvestigation was conducted. The results showed that selection is an e...

in order to evaluate the effect of freezing stress on safflower (carthamus tinctorius l.) genotypes, an experiment was conducted in faculty of agriculture, ferdowsi university of mashhad, iran. treatments included 6 genotypes (k.w.3, k.w.6, k.w.16, zarghan 279, line 295 and il-111) and freezing temperatures (0, -4, -8, -12, -16 and -20 ˚c). the trial was arranged as factorial based on completel...

in order to study the effects of drought stress on yield and yield components of safflower genotypes, a split plot based on randomized complete block design with four replications was performed at the research field, islamic azad university, arak, iran during summer of 2009. irrigation treatments included three levels of 100, 75 and 50% crop water requirement and four levels of safflower genoty...
