1. Mariner 11 is a 94 clone synthetic variety. Parent plants were selected out of forage yield plots near Marshfield, Wisconsin, for resistance to Phytophthora root rot, bacterial wilt, Fusarium wilt, Aphanomyces root rot; crowns free of crown rot and expression of branch roots. Germplasm sources are: Ladak (13%), M. varia (18%), Turkistan (10%), Flemish (41%), and unknown (18%).
2. Mariner II is adapted to and intended for use in the north central and east central region of the United States. The states where it has been tested are Minnesota, Indiana, and Wisconsin.

It has not been tested for spotted alfalfa aphid and blue alfalfa aphid.
5. Breeder seed (syn1) was produced from bulking seed of greenhouse hand crossing parent plants near Clinton, Wisconsin, in 1994. Foundation seed (syn2) was produced from breeder seed and certified seed (syn3) from foundation seed. One generation each of breeder, foundation and certified seed classes are recognized. A maximum of three years each is permitted on stands producing breeder and foundation seed with five years for certified seed. Sufficient breeder seed for the projected life of the variety will be maintained by Dairyland Research International.
