LIGHTSPROUT: medium to large size, broad cylindrical, medium number of root tips, short lateral shoots
LIGHTSPROUT BASE: medium intensity of anthocyanin colouration, absent or low proportion of blue in the anthocyanin colouration, sparse to medium pubescence
LIGHTSPROUT TIP: small size in relation to base, closed habit, absent or very weak intensity of anthocyanin colouration, very sparse to sparse pubescence

Origin & Breeding History: The origin of 'Miranda' is the result of a cross made in 1992 between 'Agria' and AG 84-009 at the breeding station in Windeby, Schleswig-Holstein, Germany. The selection criteria included high yield, high resistances to main diseases and medium to high starch content feasible also for fry production.

Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
