Origin & Breeding History: 'Nicogreen' originated from a controlled cross-pollination between the variety 'Delcorf', as the female parent, and the variety 'Granny Smith', as the male parent, in May 1989 in Sint-Truiden, Belgium. Seeds were harvested from the cross-pollinated fruit in November 1989 and germinated in March 1990 at the University of Leuven in Belgium. Between 1990 and 1991, the resulting seedlings were grown in a nursery at K.U. Leuven in Belgium. In the winter of 1991 to 1992, the top end of the seedlings were grafted onto M27 VF rootstocks. In 1992 and 1993, the bench grafted genotypes were cultivated in the fruit tree nursery of NV Johan Nicolaï in Sint-Truiden, Belgium and in March 1994, they were replanted to the 1st screening parcel of NV Johan Nicolaï in Fernelmont, Belgium. In September 1996, first fruit was observed and the new variety was selected for further evaluation. In the winter of 1996 to 1997, 35 trees were grafted onto M9 rootstocks and in March 1998 planted on 2nd screening parcel of NV Johan Nicolaï in Sint-Truiden, Belgium. Between September 1999 and 2003, observations were made and final selection of the trees occurred. 'Nicogreen' was selected based on its fruit quality, storability and appearance.

Tests & Trials: The comparative trial of 'Nicogreen' was conducted in 2014 and 2015 in the Summerland Varieties Corporation test plot, at 4200 Block, Highway 97, in Summerland, British Columbia, Canada. The trial was planted in 2012 and included 9 trees each of the candidate and reference varieties which were grafted onto rootstock variety 'M9' using a super spindle planting scheme. The trees were planted 0.45 metres apart in rows that were spaced 3 metres apart from each other. Observations and measurements were taken from 9 plants, or 10 parts of plants, of the candidate and reference varieties.
