Origin & Breeding History: 'Mendel' (experimental designation MP1835) is the result of the cross 9427004/Carneval made in 1999 in Morden, Manitoba. The main objectives of the cross were to combine the high yielding, good lodging resistance and good bleaching resistance from the parents. The breeding method is pedigree selection in combination with single seed descent.
Tests & Trials: Tests and trials were conducted during the summers of 2007 and 2008 in Lacombe, Alberta. Trials consisted of 4 replicates per variety, 5 x 1 meter with 20 cm row space. The seeding rate was 85 germinating seeds per meter square.
