The disclosure relates to a series of independent human-induced non-transgenic mutations found at one or more of the Lip1 genes of a plant； plants having these mutations in one or more of their Lip1 genes； and a method of creating and finding similar and/or additional mutations of Lip1 by screening pooled and/or individual plants. The plants disclosed herein exhibit decreased lipase activity without having the inclusion of foreign nucleic acids in their genomes. Additionally, products produced from the plants disclosed herein exhibit increased hydrolytic and oxidative stability and increased shelf life without having the inclusion of foreign nucleic acids in their genomes.
