“…Lawhon et al (1977) Statistically, fatty acid contents showed differences for all traits except myristic acid and linolenic acid. The range of measured variation in the individual fatty acids in this work was similar to the range of variation reported in most prior studies (Yunusova et al, 1991). The range of values for individual fatty acids tended to be slightly broader than the range reflected in the Codex alimentarius trading standard for cottonseed oil (FAO/WHO Food Standards, 1999).…”

“…Palmitic and stearic acids collectively constitute the saturated fatty acid. In earlier studies, the cotton genotypes and their hybrids were analyzed for fatty acid composition and significant variation was observed in their mean values ranging from 23.2 to 45.3% (Yunusova et al, 1991). Hall (2003) evaluated eleven cotton genotypes and reported greater genetic variability among the genotypes for fatty acids composition (ranged from 30.30 to 24.80%) and that range could be used to screen the cotton germplasm for various environments.…”

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.

“…hirsutum genotypes and hybrids and concluded that the fatty acids in cottonseed lines significantly differ and the degree of variability of fatty acids was influenced by the conditions during the period of the formation and ripening of the seeds, and these researchers were able to recommend lines as donors to improve the food-value indices of cottonseed oil [ 13 ]. They also observed that higher levels of saturated fatty acids occurred in the second year, with lower average humidity and higher temperature compared with the conditions of the first year [ 13 ]. This observation was in agreement with those found by others [ 2 ] in that the higher temperatures and drier growing conditions reduced linoleic acid and increased saturated fatty acids, and this response of fatty acids was dependent on genotype.…”

Water Stress and Foliar Boron Application Altered Cell Wall Boron and Seed Nutrition in Near-Isogenic Cotton Lines Expressing Fuzzy and Fuzzless Seed Phenotypes

Our previous research, conducted under well-watered conditions without fertilizer application, showed that fuzziness cottonseed trait resulted in cottonseed nutrition differences between fuzzy (F) and fuzzless (N) cottonseed. Under water stress conditions, B mobility is further limited, inhibiting B movement within the plant, affecting seed nutrition (quality). Therefore, we hypothesized that both foliar B and water stress can affect B mobility, altering cottonseed protein, oil, and mineral nutrition. The objective of the current research was to evaluate the effects of the fuzziness seed trait on boron (B) and seed nutrition under water stress and foliar B application using near-isogenic cotton lines (NILs) grown in a repeated greenhouse experiment. Plants were grown under-well watered conditions (The soil water potential was kept between -15 to -20 kPa, considered field capacity) and water stress conditions (soil water potential between -100 and -150 kPa, stressed conditions). Foliar B was applied at a rate of 1.8 kg B ha-1 as H3BO3. Under well-watered conditions without B the concentrations of seed oil in N lines were higher than in F lines, and seed K and N levels were lower in N lines than in F lines. Concentrations of K, N, and B in leaves were higher in N lines than in F lines, opposing the trend in seeds. Water-stress resulted in higher seed protein concentrations, and the contribution of cell wall (structural) B to the total B exceeded 90%, supporting the structural role of B in plants. Foliar B application under well-watered conditions resulted in higher seed protein, oil, C, N, and B in only some lines. This research showed that cottonseed nutrition differences can occur due to seed fuzziness trait, and water stress and foliar B application can alter cottonseed nutrition.

“…It has been demonstrated that both the oil and protein components of cottonseed exhibit genetic variation (Cherry et al, 1986). It is also known that seed gossypol levels can vary dramatically among G. hirsutum cultivars (Pons et al, 1953; Stansbury et al, 1956; Stipanovic et al, 2005; Romano and Scheffler, 2008), and surveys of seed fatty acid composition indicate that some genetic variability exists among cotton genotypes and cultivars (Yunusova et al, 1991; Lukonge et al, 2007; Dowd et al, 2010). Sufficient variation appears to exist for some traits to allow breeding for altered or improved seed composition.…”

Despite continued utilization of cottonseed {Gossypium hirsutum L.), little information exists regarding the effect of production factors on cottonseed composition. The objective of this study was to determine how irrigation regime and planting date affect cottonseed composition. Six cotton cultivars were planted early (late April) and at a normal time (late IVlay) in a field near Stoneville, MS, from 2005 to 2008. Half of the plots were irrigated and half were cultivated dry. Seed from the 2006 through 2008 seasons were analyzed for protein, crude oil, gossypol, soluble carbohydrates, and the oil's fatty acid composition. Irrigation increased oil and total soluble carbohydrate levels by 7 and 4%, respectively, and reduced protein levels by 10%. Irrigation also increased the level of total gossypol by 21%, modestly decreased the percentage of the gossypol (+) isomer, and slightly decreased the level of saturated fatty acids in the oii. Early planting decreased gossypol in the seed kernel by 8% under dryland conditions but not under irrigated conditions. The early planting effect on the fatty acid distribution was similar to the effect observed under dryland conditions, but the differences were more modest. Early planting and irrigation offer potential for improved fiber and seed yieid but with altered seed composition. Given the proper economic incentives, producers could alter some production strategies to produce seed with more valuable composition traits.
