Braeburn 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. It was then cultivated by the Williams Brothers nursery as a potential export variety. It is a seedling from the 'Lady Hamilton' apple. The apple itself is named after Braeburn Orchard near Motueka, where it was first commercially grown. Braeburn apples have a combination
Morphism of algebraic varieties Morphism of algebraic varieties In algebraic geometry, a morphism between algebraic varieties is a function between the varieties that is given locally by polynomials. It is also called a regular map. A morphism from an algebraic variety to the affine line is also called a regular function. A regular map whose inverse is also regular is called biregular, and they are isomorphisms in the category of algebraic varieties. Because regular and biregular are very restrictive conditions – there are no non-constant regular functions on projective varieties – the weaker condition of a rational map and birational maps are frequently used
