The cultivar Collinson produces no viable pollen and must have pollen from another cultivar. Avocados can be easily grown from seed but the cultivars are very heterozygous and therefore are more efficiently propagated vegetatively. Grafts are made with different races and Mexican rootstocks are considered to be very valuable because of their resistance to cold, but aren't compatible with W. Indian scions. Guatemalan and hybrid scions are successful on stocks of all races. There are genetic factors that control biennial bearing.
Avocados are very nutritious with large amounts of protein, vitamins and oils.
The oil is similar to olive oil and is highly digestible. The oil commands a high price and has the highest energy value of any fruit. The industrial importance of the fruit is derived from its oil, which is used widely in the preparation of cosmetics. Pests are known to cause problems, but generally Just in the native ranges. Very little pest control is necessary in areas where it has been introduced.
