S795 coffee

S795 (Selection-795) is a coffee cultivar important for being one of the first strains of C. arabica found to be resistant to coffee leaf rust (CLR).[1]

A branch of S795 coffee shrub with well developing nodes.

It is a selection of the Balehonnur Coffee Research Station in India and it is believed to have originated as a natural hybrid between C. arabica and C. liberica known as S288 and the Kent variety,[2] a hybrid of Typica and an unknown other type.[3] Both S288 and Kent are known to be resistant to many rust races and the Kent variety is a high-yielding tree. The resultant S795 cultivar exhibits rust resistance, high yield, and a good cup profile, making it a highly desirable cultivar.

S795 is widely planted in India and Indonesia. In India, it represents 25-30% of the acreage of arabica coffee.[4]

Description

S795 is a tall and vigorous shrub producing a high number of primary and secondary plagiotropic branches. The fruit (cherries) are medium in size and oblong in shape and progress from green when young to dark red when ripe. Each node produces around 14 - 16 cherries. New leaves are a light bronze color[5]
