improvement of resistance to pythium ultimum in safflower by selection under field conditions
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...
متن کاملcrossability and resistance to pythium ultimum in three different species of the genus safflower (carthamus)
identification and transfer of desirable genes from wild relatives to crop species is one of the breeding solutions for producing resistance to pathogens and pests. this study was conducted to evaluate crossability and the response to pythium ultimum in three species of the genus carthamus. to assess response to the pathogen, eight safflower (carthamus tinctorius l) genotypes, two ecotypes of c...
متن کاملevaluation of safflower genotypes to find genetic sources of resistance to damping-off (pythium ultimum)
damping-off is an important disease of safflower in iran, that caused by pythium ultimum. because of its importance, fungi isolates were sampled from infected plants grown in research farm of the college of agriculture, gorgan university of agricultural sciences and natural resources, in 2006. also it has been proved that the disease caused by pythium ultimum. evaluation of seventeen safflower ...
متن کاملImproving field establishment of safflower in soils infected by Phytophthora drechsleri and Pythium ultimum
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...
