Le Roy Lloyd's Coffee (Laurina; Bourbon Pointu) bourbon pointed body
From the mutation of Bourbon, it is a variety of var. Laurinan DC, the tree is short and conical, with small leaves, but the beans are of good quality-slightly sour, low bitter, meticulous, with attractive aromas of vanilla, citrus, almonds and lychees. The yield is sometimes abundant, sometimes apologetic, extremely drought-tolerant and susceptible to leaf rust. Diseases and insect pests nearly wiped out this variety in 1880.
The mutant is small-grain coffee, which is different from Mokka in that mocha is round beans and Laurina is sharp at both ends, so it is called "bourbon pointed body". In fact, both come from mutations in the same gene. All are multiple mutations (one gene causes several morphological changes, such as low or small changes in tree height, internodes, leaves, and caffeine content, while other mutations cause only a small change, if true color).
When crossed with normal coffee, the first offspring were normal, and the second offspring were both normal and dwarf plants.
Genetic factor is a pair of recessive lrlr, lack of caffeine synthase, can not synthesize caffeine from theobromine.
[Bourbon Pointu] Bourbon pointed body Coffea arabica var. Laurina
In 1771, Leroy discovered this mutant of Bourbon on Bourbon Island. The bean shape changed from round to pointed. The caffeine content was less than half of that of Bourbon (1.2%), and only 0.4% of it. The flavor of the general low-caffeinated coffee variety was not good enough, but the pointed bourbon broke this rule. The flavor was excellent, and it was as legendary as a geisha. Frail and low output, extremely precious, used to be the most expensive, the most sought-after coffee (about 200 murmur300 euros / kg), in Japan has set a record of 80,000 yen / kg, as soon as it is launched! At present, most of them only supply the Japanese market.

Analysis and summary of genetic variation of coffee plants
Professional baristas exchange please pay attention to the coffee workshop (Wechat official account cafe_style) narrow leaf mutation Angustifolia leaves long and narrow, long lanceolate leaf varieties are the main parent source of coffee breeding. About 5% of C. arabica seedlings have narrow leaves. The recessive factor of two pairs of mutations of ag1 and ag2 was crossed with normal plant. The first generation was normal and the second generation was 9 positive.

Professional barista communication please follow the coffee workshop (Wechat official account cafe_style) large mutation Maragogype from Typica. The plant characters of this mutant variety are taller than that of common coffee, but the yield is lower. The genetic factor is a pair of dominant Mg, and the offspring of crossing with normal caffeine are large, but the yield is higher, so they are often used as rootstocks and hybrid parents.
