The Sugar Prune and Its Parents 



Mr. Burbank's Sugar Prune was developed by selection 



from a cross between the French prune and the Hungarian prune. 



From the former it inherited sweetness and flavor andjromthe latter size. 



It improved on each parent, however, manifesting the vigor that is 



not unusual ivith hybrids. The French prune is still 



largely grown in California, but its improved 



descendants must ultimately displace it.
