Abstract:

Oil content is one of the important quality traits and the main object of the breeders to improve quality traits in peanut. In this paper, the composition and proportion of the peanut oil content were briefly described, the impact of external factors on peanut oil content in the three aspects of the environmental factors, nutrients and other related traits was reviewed. The genetic research progress of the peanut oil content in classic and molecular quantitative genetics was summarized. In addition, the method of improving the peanut oil content was made in the four aspects, that applying practicable agronomic control measures, coordinating the relationship among closely related traits, using modern breeding techniques to assisted selection and clarifying the genetic mechanism of the oil content on the molecular level.
