The contents of fat and sucrose are important factors to peanut quality, and revealing their hereditary properties is critical to improve the quality in peanut. In this study, the analysis of embryo, cytoplasm, and maternal effects for fat and sucrose contents in peanut seed were conducted by using general genetic model. Five peanut lines with significantly different fat and sucrose contents were selected as parents for incomplete diallel crosses. The results indicated that the fat content was mainly controlled by embryo additive effect, followed by maternal additive effect. The sucrose content was primarily governed by maternal additive effect. Correlation analysis showed that there was a significantly negative correlation between fat and sucrose contents in peanut seed (r = -0.886**), which was mostly managed by embryo additive and cytoplasmic effects. Predicted genetic effects suggested that 18-1951 with high fat content and JHT1 with high sucrose content were superior donor parents for improving the contents of fat and sucrose in peanut, respectively.
