Interpretive Summary: Seedless fruit and vegetables are very popular with consumers. Over the years, breeders have taken advantage of natural mutations and new technologies to provide these seedless varieties. Stone fruit, such as peaches, plums, cherries, and apricots, not only contain a seed but the seed is surrounded by a hard shell, the stone. Currently, there are no stoneless and seedless varieties available. The article reviews what is known about stone developent and seed development, and the possible approaches to breed for stoneless and seedless plums.

Technical Abstract: Luther Burbank began a breeding program to produce stoneless plums (Prunus domestica) over 100 years ago. He released two plums, 'Miracle' and 'Conquest', whose fruit contained only a very small part of the stone. These plums are no longer available. In today's world of convenience, a plum that does not contain either the stone or the seed might be very welcome. Is it possible to again produce plum cultivars that are completely stoneless and seedless? A combination of gained knowledge in genetics and breeding, molecular technology, and remnants of stoneless germplasm, probably from Burbank's program, suggest that it is possible to now produce a pitless plum.
