The commercial Nigerian peanut cultivars Ex-Dakar, Samnut-22 and Samnut-26, the Egyptian cultivar Ismailia-1 and the American cultivar NC-7 were genetically differentiated and the cultivars’ effects on growth and yield components, total lipid contents, including saturated and unsaturated fatty acids, and oil body size and number were investigated. Experiments were carried out at Cairo University Research Station, Giza, Egypt, during the summer seasons of 2016 and 2017. All cultivars had high contents of total unsaturated fatty acids and low contents of saturated fatty acids. Variations among tested cultivars in oil body size and number were documented and cultivars were ranked based on their oil bodies’ size as Ismailia-1 > Samnut-26 > NC-7 > Ex-Dakar ≥ Samnut-22. Oil body size and number were inversely related. This variation can be explained by the different amounts of acidic amino acids and the protein structure on the surface of the oil bodies of these cultivars. The distributions of protein bodies and oil bodies seemed to be negatively correlated. Cultivar effect was significant, and variation was found in seed production and quality in addition to the size and number of oil bodies, oil productivity, and oil quality among cultivars. Seasonal effects were not evident due to the stability of the climatic conditions during the two seasons of the study.

花生（Arachis hypogaea L.）品种的生产力，脂肪酸概况，油体超微结构和分子标记之间的关联

对商品化的尼日利亚花生品种Ex-Dakar，Samnut-22和Samnut-26，埃及品种Ismailia-1和美国品种NC-7进行了遗传分化，这些品种对生长和产量构成，总脂质含量（包括饱和）的影响和不饱和脂肪酸，以及油体的大小和数量进行了研究。在2016年和2017年夏季，在埃及吉萨的开罗大学研究站进行了实验。所有品种的总不饱和脂肪酸含量高，饱和脂肪酸含量低。记录了受试品种油体大小和数量的差异，并根据油体大小对品种进行了分类，依次为Ismailia-1> Samnut-26> NC-7> Ex-Dakar≥Samnut-22。油体的大小和数量成反比。这些差异可以通过这些品种油质表面酸性氨基酸的不同含量和蛋白质结构来解释。蛋白质体和油体的分布似乎呈负相关。品种效应显着，除油体的大小和数量，产油量和品种之间的油质外，种子产量和质量也存在差异。由于在研究的两个季节中气候条件的稳定性，季节性影响不明显。除油体的大小和数量，油生产力和品种之间的油质外，还发现种子产量和质量存在差异。由于在研究的两个季节中气候条件的稳定性，季节性影响不明显。除油体的大小和数量，油生产率和品种之间的油质外，还发现种子的产量和质量存在差异。由于在研究的两个季节中气候条件的稳定性，季节性影响不明显。
