Gala (apple) total volume of the commercial production of eating apples grown in the UK, often replacing Cox's Orange Pippin. Many sports of Gala have been selected, mostly for increased red color, including the popular "Royal Gala". The original cultivar produced fruit with orange stripes and a partial orange blush over a yellow background. Since then, several un-patented sports have been recognized. Additionally, more than twenty sports have received US plant patents: Unpatented varieties include: Auvil, Imperial Gala apples are grown from May through September in the northern hemisphere, but, like most apples, are available almost all year through the use of
Braeburn 3–4 months, and in CA for 8–10 months, with only a slight susceptibility to scalding although it is sensitive to carbon dioxide. The variety has a relatively impermeable skin, which restricts diffusion of gases into and out of the fruit, leading to high internal carbon dioxide concentrations. The browning disorder seems worse in overmature fruit, fruit from lightly cropped trees, and large fruit, but it can show up on different trees in different years, and in some regions, but not others. Maintaining the superior qualities of Braeburn while eliminating Braeburn browning disorder led to development of the Jazz cultivar. Since
