Varieties used for comparison: 'Andover', 'Dakota Pearl' and 'Superior'
Summary: The intensity of anthocyanin colouration at the base of the lightsprout for 'Boustifailles' is absent or very weak whereas it is strong for 'Andover' and strong to very strong for 'Dakota Pearl'. At the base of the lightsprout, the proportion of blue is absent or low on 'Boustifailles' whereas the proportion of blue is medium on the lightsprout of 'Andover' and high on 'Dakota Pearl'. The pubescence on the base of the lightsprout of 'Boustifailles' is absent or very sparse while it is very dense for 'Andover' and dense for 'Superior'. The intensity of anthocyanin colouration at the tip of the lightsprout for 'Boustifailles' is absent or very weak whereas it is strong to very strong for 'Dakota Pearl'. The plant of 'Boustifailles' has a semi-upright growth habit while the plant of 'Andover' has an upright growth habit. The second pair of lateral leaflets are small for 'Boustifailles' whereas they are large for 'Andover' and medium sized for 'Superior'. The frequency of coalescence of the terminal and lateral leaflets is absent to very low for 'Boustifailles' while it is of medium frequency for 'Dakota Pearl'. The extent of anthocyanin colouration on the flower bud of 'Boustifailles' is absent or very low while it is of medium extent for 'Dakota Pearl' and 'Superior'. The inflorescence of 'Boustifailles' is medium sized while it is small for 'Dakota Pearl' and large for 'Superior'. The intensity of anthocyanin colouration on the inner side of the corolla for 'Boustifailles' is weak whereas it is absent or very weak on 'Andover' and 'Dakota Pearl' and medium to strong on 'Superior'. The plant of 'Boustifailles' matures late to very late season while the plant of 'Andover' and 'Dakota Pearl' matures mid-season and that of 'Superior' matures early to mid-season. The flesh of the tuber of 'Boustifailles' is medium yellow while it is cream coloured for 'Andover' and 'Superior' and light yellow for 'Dakota Pearl'.

Origin & Breeding History: 'Boustifailles' (experimental designation QP00053.02) originated from a controlled cross made by the Centre de recherche des Buissons in 2000, at Pointe-aux-Outardes, Quebec between 'Delta Gold', as the female parent, and 'Andover', as the male parent. In 2001, true potato seeds from this cross were sown in a greenhouse, and the resulting seedling tubers were planted in the field at the Centre de recherche des Buissons. A clone designated as QP00053.02 was selected in 2002 and evaluated for 4 generations from 2003 to 2006. In 2007, screening trials were conducted at Pointe-aux-Outardes and in Ste-Ubalde, Quebec to assess the time of maturity. The selection criteria used in the field and laboratory included yield, visual appearance; tuber size, shape, density; culinary quality, incidence of tuber defects, fry and chip colour from processing, maturation and the reaction to common scab, rhizoctonia and other diseases. From 2008 to 2010, additional field testing was done at three locations in Quebec.
Tests & Trials: The comparative trial for 'Boustifailles' was conducted during the 2017 growing season at Ste-Croix de Lotbinière, Quebec. The trial consisted of 4 replicates, a total of 68 plants for each variety, grown in 5.1 metre length rows spaced 92 centimetres apart. The plants were spaced 30 centimetres apart within the row. The measurements were taken from 10 plants, or parts of plants, of each variety.
