“…It is noteworthy that oil and protein production is a fundamental aim in the oilseed cultivation of plants like safflower. The negative correlation between seed oil and protein content is known from various oilseeds, and this association may be due to tight linkage between oil and protein alleles in the repulsion phase or to pleiotropic effects (Yu et al, 2012). Environmental factors during the seed-filling period and even during the flowering stage can widely affect seed yield and seed quality of oilseed crops (Monotti, 2003).…”

Safflower is one of the most adapted oilseed crops to the drought-prone arid lands. This experiment was carried out to evaluate the effects of water deficiency on some physiological traits such as proline content, soluble carbohydrate content, relative water content (RWC), and seed quality using 64 safflower genotypes grown under normal and water-deficient field conditions. Plants were grown under normal irrigation until the branching growth stage, when water deficiency was applied to the plants. Results of combined analysis of variance showed the significant effects of genotype, water deficiency, and their interactions on the tested traits. RWC, seed oil content, and oil yield significantly decreased whereas proline, soluble carbohydrate, and protein content increased in response to water deficiency. Cluster analysis divided genotypes into 3 groups of sensitive, tolerant, and semitolerant genotypes under water-deficient conditions. The second group (tolerant group) possessed the lowest seed yield loss due to water stress and produced the highest seed protein content and seed oil yield under water-deficient conditions. The superior seed yield and quality was closely related to the physiological properties of the plants, resulting in higher leaf proline, carbohydrate, and RWC under water-deficient conditions. The results suggest that leaf proline content, carbohydrate content, and RWC would be useful traits to select for water stress-tolerant plants in safflower.

“…For every 100 kg of lint fiber ginned from cotton, 150 kg of cottonseed is produced (Yu et al, 2012). Thus, cottonseed is an abundant resource for oil, meal and protein for human consumption, animal feed, and industrial raw material (Coppock et al, 1987;Gao et al, 2010;He et al, 2013a;2014a;2014b;Kandasamy et al, 2008;Zhang et al, 2009).…”

Whole cottonseed and its derived products can be used as human food, animal feed, and industrial raw material. Chemical composition of cottonseed is one of the critical parameters for evaluating its quality and potential end use. Especially, protein and dietary fibers are two desirable nutritional properties of cottonseed for animal feed. In this study, we determined their contents in cottonseed harvested from different fertilization managements with or without wheat cover crop in two consecutive years. Seed content of crude protein increased in the order of no fertilizer ≤ poultry litter ≤ chemical fertilizer. Both neutral and acid detergent fiber profiles were affected by fertilization and planting year/cover crop in an order reversing that of crude protein. Few statistically significant (P>0.05) impacts were observed on the content of acid detergent lignin. Observations derived from this work will provide information on nutritional value and digestibility of cottonseed as affected by cropping management practices.

“…The five largest cottonseed producing countries (China 26.4%, India 25.8%, USA 10.7%, Pakistan 7.9%, Brazil 6.5%) currently account for 77.3% of global output (ICAC, 2015). Cotton fiber is a source of natural textile, and cottonseed is a source of oil for human consumption, cotton meal and minerals for livestock feed (Yu et al, 2012;He et al, 2013). Therefore, maintaining high quality fiber and cottonseed nutritional value is critical.…”

“…Recently, cotton has attracted much attention as a biofuel crop (Chesterfield et al, 2013), however, information on the genetic basis of cottonseed oil and protein contents is lacking (Jiwen et al, 2012). For improving the quantity and quality of cottonseed oil content, various breeding procedures have been employed with different levels of success (Cherry et al, 1981;Dani, 1990).…”

The increase in the population at the global level necessitates to explore promising approaches to increase food supply, including protein and oil, to meet the needs of the people. Cotton is one of the most important oil producing crops and cottonseed meal provides important protein nutrients as animal feed. However, information on the genetic basis of cottonseed oil and protein contents is lacking. In this study; protein contents, oil and fatty acid composition of 124 cotton genotypes were observed for developing new cultivars. Accelerated Solvent Extraction method used for determining fat ratio; Gas Chromatography employed for fatty acid analysis while protein contents were analyzed by Kjeldahl method. Average crude oil 31.0%, total fat contents varied from 23.11 to 37.70% while mean protein content 38.0% were observed among genotypes. The dominating fatty acids included linoleic acid, palmitic acid and oleic acid (46.91, 25.73 and 20.21%) respectively, while linolenic acid (0.13%), γ-linolenic (0.33%), palmitoleic acid (0.64%), myristic acid (0.88%), nervonic acid (1%) and stearic acid (2.38%) had variations in fatty acid contents. Frequency distribution of the parameters showed a normal distribution and differences among genotypes for the traits studied were statistically highly significant. Prinicipal component analysis showed a complex opposite relationship with a total protein and oil contents. Genotypes; Fantom for protein, Cirpan 60 for total crude oil, Stoneville 468 and YB195 for higher amount of fatty acids especially oleic acid; can be used for improvement of cottonseed quality in breeding programs.
