Braeburn Braeburn is such a desirable variety, commercial orchards and trees in regions and locations that have proven not susceptible to the browning disorder are being maintained. Since most home orchardists do not attempt very long term storage, they do not encounter the browning disorder. Braeburn The 'Braeburn' is a cultivar of apple that is firm to the touch with a red/orange vertical streaky appearance on a yellow/green background. Its color intensity varies with different growing conditions. It was discovered as a chance seedling in 1952 by the farmer O. Moran from Waiwhero in the Moutere Hills near Motueka, New Zealand.
Algebraic variety algebraic sets. Using the Nullstellensatz and related results, mathematicians have established a strong correspondence between questions on algebraic sets and questions of ring theory. This correspondence is a defining feature of algebraic geometry. An "affine variety" over an algebraically closed field is conceptually the easiest type of variety to define, which will be done in this section. Next, one can define projective and quasi-projective varieties in a similar way. The most general definition of a variety is obtained by patching together smaller quasi-projective varieties. It is not obvious that one can construct genuinely new examples of varieties in this way,
