• What is cottonseed oil?
  • Cottonseed oil is cooking oil from the seeds of cotton plants of various species, mainly Gossypium hirsutum and Gossypium herbaceum, that are grown for cotton fiber, animal feed, and oil.
  • Is there a genetic improvement in oil accumulation of cottonseed?
  • However, the genetic improvement in oil accumulation of cottonseed is constrained by the rather limited variation among the elite Upland cotton (G. hirsutum) cultivars and lines as the result of extensive selection within the species toward improving lint yield and quality.
  • Can cottonseed be used as a biofuel?
  • As a byproduct in cotton production, cottonseed has excellent potential for use as a source of sustainable, high quality vegetable oil, biofuel and proteins because of its abundance that is expected to grow as the demand for cotton fiber continues to increase.
  • Will increasing oil content affect cottonseed value & sustainability?
  • Research efforts to increase the oil content of cottonseed, which will most likely also decrease the level of protein, will actually have a positive impact on cottonseed value and sustainability metrics due to being able to reduce the level of fertilizer (mainly supplemental nitrogen) applied to the plant to support protein production in the seed.
  • Is there genetic variation in cottonseed oil and protein content?
  • The focus of cotton breeding on high yield and better fiber quality has substantially reduced the natural genetic variation available for effective cottonseed quality improvement within Upland cotton. However, genetic variation in cottonseed oil and protein content exists within the genus of Gossypium and cultivated cotton.
  • What is cottonseed oil (CSO)?
  • The worldwide cottonseed production in 2019¨C2020 was 43 million metric ton (Kumar et al. 2022). Cottonseed oil (CSO) is the by-product of cotton manufacturer; extracted from the decorticated and delinted cottonseed for their used as edible oil and industrial applications (Orhevba and Efomah 2012; Shah 2017).
