Contextualization: Pumpkin seed is rich in ether extract with a high quantity of long-chain polyunsaturated fatty acids content. Knowledge gap: It is unknown how inbreeding influences the ether extract character in pumpkin seeds. Purpose: It aimed to evaluate the behavior of ether extract content and its characteristics associated to the seed of C. moschata pumpkin genotypes in three generations of inbreeding S0, S1, and S2 and to identify the predominant fatty acids in the best genotype. Methodology: A randomized complete block design was used with six (6) genotypes, four (4) repetitions, and five (5) plants per experimental unit. Inbreeding depression (ID) between generations was evaluated for the ether extract (EE), seed weight per fruit (PSPF, in Spanish), seed unit weight (PUS, in Spanish), and number of seeds per fruit (NSPF) variables. Gas chromatography coupled with mass spectrometry (GC/MC) was used to identify the fatty acids present in the EE. Results and conclusions: In genotypes 129 and 160, when passing from generation S0 to S1, they did not have ID in the EE character, and when passing from generation S1 to S2, only genotype 129 had ID; the other genotypes increased the EE content. There were fluctuations between genotypes for the variables PSPF, PUS, and NSPF in which no differentiating factor between generations was identified. When analyzing the EE, it was identified that 66.98% corresponds to monounsaturated and polyunsaturated fatty acids, of which 60.15% corresponds to oleic acid, and squalene, which is scarcely present in oilseeds, was found among the components.
