Variety Description

Variety used for comparison: 'Elfe'

Summary: The lightsprout of 'Ivetta' is ovoid whereas that of 'Elfe' is broad cylindrical in shape. The intensity of anthocyanin colouration on the lightsprout of 'Ivetta' is strong at the base and of medium intensity at the tip whereas it is of medium intensity at the base and absent or very weak to weak at the tip of the lightsprout for 'Elfe'. In relation to the base of the lightsprout, the tip of the lightsprout is medium sized for 'Ivetta' whereas it is small for 'Elfe'. The tip of the lightsprout of 'Ivetta' has an intermediate habit whereas 'Elfe' has a closed habit. The extent of anthocyanin colouration on the stem of 'Ivetta' is absent or very low whereas the extent is low for 'Elfe'. The frequency of coalescence of the terminal and lateral leaflets is absent or very low for 'Ivetta' whereas the frequency is low for 'Elfe'. The plants of 'Ivetta' are taller than those of 'Elfe'. The anthocyanin colouration on the inner side of the corolla is of low to medium extent and of weak to medium intensity for 'Ivetta' whereas for 'Elfe', the extent of anthocyanin colouration on the inner side of the corolla is absent or very low and the intensity is absent or very weak.

Origin & Breeding History: 'Ivetta' originated from a cross between 'L 98/961/195' and 'B98/222/122', conducted in 2003 in Ebstorf (Lower Saxon), Germany. From the resulting progeny, 'Ivetta' was selected, based on positive agronomic criteria, in 2004.

Tests & Trials: The comparative trial for 'Ivetta' was conducted by Global Agri Services Inc. during the 2018 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row containing 70 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean difference was significant at the 5% probability level based on a paired Student's t-test.
