Jaeger 70 (also known as Munson) is a hybrid of two Americangrape species, Vitis lincecumii and Vitis rupestris developed by Hermann Jaeger (1844–1895), a Swiss-American who settled in Missouri. He named the successful hybrid for his friend and fellow grape breeder, T.V. Munson. However the grape has become better known by Jaeger's selection number, 70. The grape's primary importance is as the female progenitor of many French - American hybrid grapes in the breeding program run by viticulturist Albert Seibel, whose crosses are known as Seibel grapes.
