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...

Safflower (Carthamus tinctorius L.) is a highly adaptable but underutilized oilseed crop capable of growing in marginal environments, with crucial agronomical, commercial, and industrial uses. Considerable research still needed to develop commercially relevant varieties, requiring effective, high-throughput digital phenotyping identify key selection traits. In this study, field trials comprisin...

abstract downy mildew of cucurbits is one of the most important diseases of cucumber in humid areas and greenhouses. damage of disease is estimated 50% to 100% in suitable climatic conditions. therefore, achieving resistant or tolerant genotypes can be designed as the most important and safe method to reduce the damage and increase the benefits of cucumber farming. in order to evaluate the resi...

ABSTRACT: The safflower (Carthamus tinctoriusL.) has an uneven flowering and fruiting, which can cause problems in seed production harvesting regions with hot humid climates. However, little is known about the optimal harvest time. Therefore, this study evaluated optimumtiming for of three genotypes (2106, S-325, 7329).The experiment was a randomized complete block design six replications. star...

introduction considering the nutrient loss, environmental pollution and increase in production costs on account of chemical fertilizer application, supplying mineral nutrients based on organic sources and mycorrhizal inoculation can improve organic matter content in soil (khandan & astaraei, 2005; halajnia et al., 2007), promote sustainable production of oil crops (mostafavian et al., 2008; kaw...

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...
