“…The average outcrossing rate at 1-1.5 m was 26% with a range of 8.3-53% at the plant level. This rate was approximately twice that reported by Velasco, Fischer and Fernandez-Martinez (2012).…”

“…Average outcrossing rates of 5.7%, 12.1% and 13.2% were observed respectively. Higher outcrossing frequencies were detected at the single plant level (up to 35.9%) and the single-head level (up to 58.3%) (Velasco, Fischer and Fernandez-Martinez 2012).…”

“…Nabloussi, Velasco and Fernandez-Martinez (2013) used the same cultivars and field layout as Velasco, Fischer and Fernandez-Martinez (2012) to determine the outcrossing frequencies under Moroccan conditions. The average outcrossing rate at 1-1.5 m was 26% with a range of 8.3-53% at the plant level.…”

“…One reason for this is the environmental differences that can influence outcrossing rates. For example, both Velasco, Fischer and Fernandez-Martinez (2012) and Nabloussi, Velasco and Fernandez-Martinez (2013) used the same cultivars and field designs in different countries (Spain versus Morocco) but had a twofold difference in outcrossing rates. The outcrossing rates could also be influenced by the cultivars included in the study.…”

From their first commercialisation in the mid-1990s, genetically engineered crops (also known as "transgenic" or "genetically modified" plants) have been approved for commercial release in an increasing number of countries, for planting, entering in the composition of foods and feeds, or use in industrial processing. The majority of these productions are for soybean, maize, cotton and rapeseed (canola) bearing pest resistance and herbicide tolerance traits, aiming to improve yields and reduce the costs of production. Other transgenic crops that are increasingly grown to date comprise lucerne (alfalfa), sugar beet, sugarcane, papaya, safflower, potato, eggplant, as well as pumpkin, apple and pineapple in smaller areas. Other traits are increasingly introduced in engineered plants, adapting them to biotic or abiotic stress, such as resistance to drought or tolerance to salt in the growing environment, or changing a characteristic, e.g. modified oil content, reduced lignin content, non-browning or nutritional quality (biofortification). Thus, transgenic crops, where adopted and available on the market, enlarge possibilities for farmers, industry and consumers. They can play a part in addressing global concerns such as the rising need for food and feed in the growing population context or the necessary adaptation of agriculture for better resilience to climate change.Modern biotechnologies are applied to plants (crops, flowers and trees) but also animals and micro-organisms. The safety of the resulting genetically engineered organisms, when released in the environment for their use in agriculture, forestry, fishery, the food and feed industry, biofuel production or other applications, represents a challenging issue. A scientifically sound approach to their risk assessment should inform biosafety regulators and support national decisions regarding their possible market release. Genetically engineered products are rigorously assessed by their developers during their elaboration and by governments when ready for commercial use, to ensure high safety standards for the environment, human food and animal feed. Such assessments are considered essential for healthy and sustainable agriculture, industry and trade.In 2019, according to the annual report of the International Service for the Acquisition of Agri-biotech Applications, the five main producers of genetically engineered crops were the United States, Brazil, Argentina, Canada and India (listed by decreasing area) covering a combined 170 million hectares representing more than 90% of the global transgenic crop area. Among the 29 countries having grown genetically engineered crops in that year, 9 of them were OECD countries, listed by decreasing area as follows: the

“…The spiny is dominant on the spineless and the orange color flower is dominant on yellow flower color (Pahlavani et al 2004). There are very few studies concerning safflower cross-pollination and hybridization (Gurbuz & Ekiz 1990;Velasco et al 2012;Nabloussi et al 2013). For this reason, this research was carried out to determine the cross-pollination ratio in safflower using different experimental designs and examine role of direction on cross-pollination.…”

This study was carried out to determine cross-pollination ratio in safflower (Carthamus tinctorius L.) using various experimental designs during summer seasons of 2012-2013. Two safflower (Carthamus tinctorius L.) cultivars having two different characters (spiny and spineless) were used as the study material. The cultivars with spiny (Balci) was used as a donor and spineless cultivar (Yenice) was used as a receptor. The results demonstrated that average cross-pollination ratio ranged between 1.12% and 7.71%. The highest cross-pollination ratio was obtained from third experimental design that receptor and donor plants were mixed in 10 rows with 50 cm row space, while the lowest ratio was in north direction of forth experimental design, which receptor plants were sown in south and north directions. Average cross-pollination ratio was 3.49% in Ankara conditions. There were differences among the experimental designs in respect to crosspollination. The results of this research showed that cross-pollination ratio decreased when distance between donor and receptor plants increased.

In this study, was conducted in 2018, 2019 and 2020 at Tekirdağ Namık Kemal University Agriculture Faculty Department of Field Crops, it was aimed to determine morphological and technological traits of some oleic and mid-oleic type safflower genotypes developed by cross breeding. For this purpose, 11 F2 hybrid genotypes obtained from a cross between Dinçer 5-18-1 cultivar and PI 603208 genotype were used as material and compared to two standard oleic local cultivars and parents of these hybrids (Dinçer 5-18-1, PI 603208, Olas ve Asol). In study to determine the agricultural and technological traits, plant height (cm), branch number, head number, head diameter (cm), 1000 seed weight (g), seed yield (kg da -1 ), hull ratio (%), oil content (%), oil yield (kg da -1 ) and fatty acid composition (%) were investigated. According to research findings, seed yield values of hybrid genotypes changed between 120.73-187.80 kg da -1 , oil content values 31.67-36.49% and oil yield values 40.43-63.92 kg da -1 and showed a wide variation. The highest oil content among hybrid genotypes were obtained from the EC/ol-7 genotype (36.49%), while the highest seed yield and oil yield among genotypes were obtained from the EC/ol-8 genotype (187.80 and 63.92 kg da -1 respectively). The highest oleic oil content among hybrid genotypes was obtained from the EC/ol-11 genotype (61.79%). In this study, it was determined that 5 genotypes in terms of oil content, seed yield and oleic acid composition (EC/ol 5, EC/ol 6, EC/ol 7, EC/ol 8 and EC/ol 11) are superior of the other genotypes in F2 generation. In addition, with the other genotypes, both stable and hopeful ones will be determined the next generations (F3 and F4).
