`SuperMac' (Malus xdomestica Borkh) is being released as a replacement for `Spartan', which is presently being grown in Eastern Canada for its excellent shelf life. However, it is susceptibility to scab [Venturia inaequalis (Cke) Wint.], the most common apple disease. This new cultivar produces larger fruit than `Spartan' and is resistant to apple scab. It is very attractive (Fig. 1), has a pleasant taste and an excellent shelf life, and keeps very well and longer compared with the `Spartan'. `SuperMac' is a `McIntosh'-type apple. The tree is hardy to ¿30 °C, and the fruit and leaves are resistant to the common races of apple scab resulting from the presence of the Vf gene derived from Malus floribunda 821.
