Yes, seedless lemons are real and are commercially available.
While most lemons naturally contain seeds, innovative breeding techniques have led to the development of lemon varieties that produce fruit with significantly fewer seeds or are entirely seedless.
One example highlighted in the provided reference describes an Australian farmer who, after years of selective breeding, identified a naturally seedless lemon tree in his orchard. This demonstrates that seedless lemons can arise from careful observation and cultivation. These lemons retain all the desirable characteristics of regular lemons, but without the inconvenience of dealing with seeds. This makes them a popular choice for consumers and chefs alike.
