110 RICHTER is a V. berlandieri x V. rupestris hybrid created by Franz Richter in 1902 and used as a rootstock. Dr Richard Smart (2015, p628) says 110R is noted for its high vigour [excellent fruit setting capacity] and thus tends to delay maturity, especially in fertile soils. 110 R has high phylloxera tolerance, low nematode tolerance, moderate lime tolerance and is quite drought tolerant [deep rooter] he says, hence it is widely used in Mediterranean climates [good for lighter, shallower soils] although initially it was not used extensively because of poor rooting in the nursery, he says.
See Bonterra’s Butler Ranch in Mendocino County, California for a case study on using this rootstock.
