Pinkerton
A Guatemalan hybrid which originated about 1959 as a ‘Rincon’ seedling on the property of John W. Pinkerton in Ventura, California and thought to be a ‘Rincon’ × ‘Hass’ hybrid; patented in 1975. (J.H. Crane et al.2002)
Characteristics of the tree
- The tree is Elongated, upright and has moderately spreading canopy
- Semidwarf, suitable for high density planting
- Fruits are found inside the canopy; this reduces the chances of fruit drop caused by high temperatures.
- Leaves has wavy pattern
- Fruit bearing capacity is greater
- Hot and subtropical variety, temperature is suitable up to 46˚C
- Flower type is A, flowering starts March to April
- Requires pollinizer variety (B type)
- Yield is 12 ton/ acre
Characteristics of Fruit
- Dark green, rough, and pebbly skin
- Medium to large sized, long necked, tear drop shaped fruits
- Weigh around 230-425g
- Seeds are comparatively smaller
- Oil content is 16 to 20%
- The pulp percentage is higher, smooth/ creamy in texture like Hass
- The flesh/pulp is golden yellow in color
- Easy to peel
- Greater skin thickness saves from postharvest damage and enhances the shelf life
- Slow ripening in nature, advantageous for transporting long distance
Ettinger
Predominantly Mexican with some Guatemalan parentage from a seedling of ‘Fuerte’ selected in Kefar Malal, Israel in 1947 (J.H. Crane et al.2013).
Characteristics of the tree
- Conical, upright, and compact growing habit, the uniform growing nature of the plant makes the harvesting process easier
- Mostly grown as pollinizer (type B) variety with the other varieties such as Hass, Lamb Hass etc. at a rate of 10-15% to induce cross pollination.
- By using this variety as a pollinizer, the production has increased by 20-30% in other varieties
- It is heat tolerant, can tolerate up to 46˚C
- Flowering starts from March and April
- The fruits are mostly found in the lower branches of the tree
- The fruit bearing capacity is moderate to heavy
Essential qualities of the fruit
- The fruit is shiny green skinned, distinct pear shaped, has slightly rough surface and does not get dull on ripening
- The seed is of large size
- Weighs about 170-570g
- The flesh is pale yellow in color and smooth and creamy in texture.
- The shelf is comparatively longer
- The problem related to this fruit is peel cracking which occurs due to fruit being pulled down by gravity as the oil content of fruit increases gradually. Timely harvesting is the only way forward to this issue
Reed
A Guatemalan type that originated on the property of James Reed in Carlsbad, California in about 1948; registered in 1960, the patent expired in 1977. It is probably an ‘Anaheim’ × ‘Nabal’ hybrid (J.H. Crane et al.2013)
Important characteristics of Reed tree
- The tree is slender, downward hanging branches protect the fruit from sunburn
- This variety due to its upright growth is conductive to ultra-high-density planting in California
- Consistent high yielding variety
- This also has heat tolerance property(46˚C)
Fruit traits of Reed
- The fruit is green, slightly pebbled, comparatively big and round
- Medium to large, the average weight is 350-500g
- The flash has pale yellow color with smooth texture and the flesh surface of cut does not darken
- The pulp quantity is high with a pleasing taste
- The seed is medium to large
- Late season maturity creates the availability of off-season fruits in the market
Hass
Overwhelmingly the most important/dominant cultivar in the world. Primarily grown in the cooler subtropical regions and at higher elevations in some tropical areas by the 1960s. (Schaffer.B et al;2002)
Tree profile
- Medium to large vigorous tree with semi upright growing habit, tall with a rounded crown, having a flower group A
- Unpruned Hass tree can attain a height up to 25 ft. (greg adler,2022)
- consistent fruiting tree, fruit drop is less compared to the Lamb Hass (greg adler,2022)
- Heat tolerance is up to 35˚C
Profile of the fruit
- Ovate shape, small to medium size, weighing 140 to 400g has pebbly skin.
- Dark green on the tree, although it may become purplish black upon maturity (Schaffer.B et al;2002)
- Seeds are satisfyingly small (greg adler,2022)
- Flesh of Hass avocado is pleasing green in color with gold towards the center
- Typical oil content of 18-20% g gives rich nutty flavor
- The texture is very smooth
- Harvesting season is late summer; the fruit may become rancid if harvested late
- Diseases and pest- Medium to thick peel provides tolerance to some extent to pest and diseases, but leaves are susceptible to Persea mite and fruits to thrips
- Excellent storage and shipping quality due to high concentration of calcium
Lamb Hass
Lamb Hass’ (California) is a seedling of ‘Gwen’ propagated by B.O. Bergh that was planted at the Lamb family ranch in Camarillo, California and patented in 1996 by the University of California (Schaffer.B et al;2002)
Tree profile
- Precocious, fruits are covered in the foliage, flowering type is A
- Has an Upright canopy which lends itself to a high-density planting
- Less susceptible to pests and damage caused by wind than Hass as fruit is held inside the tree canopy
- This variety can tolerate up to 40-42˚C
Fruit qualities
- Fruits are larger than Hass, average weight is 250-405g
- Matures several months later than Hass in cooler climates
- The peel is finely pebbled, medium thick and brittle
- The fruit turns purplish black ripening, if harvested before gaining full maturity the ripe fruit tends to be stringy (Schaffer.B et al;2002)
- The seed size is medium
- The pulp is of good to very good quality, yellow in color, has strong pleasing taste
- The texture is smooth enough
Lavi
‘Lavi’ originated from a ‘Hass’ tree pollinated in spring 1991. The fruit was harvested in winter 1991/2, the seedling was planted in 1993 in Kibbutz Lavi (after which the cultivar is named) and bore its first fruit in 1994/5. ‘Lavi’ was found to be especially interesting for being ‘Hass’ like in its form but with larger fruit. (E. Lahav, et al.2005)
The success rate of this variety is still under research as anecdotal evidences suggest that it has given good results only in 50% of the areas in Israel where it was planted.
Tree profile
- Tree is small, grows about 6m without any pruning practices. It is narrower than lamb hass and upright with dense foliage
- Leaves are flat, smooth, and medium in size
- Belongs to flowering group A
- Compared to Hass, Lavi is a better producer with a smaller tendency to alternate bearing
- Lavi can tolerate heat up to 46˚C
Fruit habits
- Ovate, uniform in shape and size
- Average fruit weight is 260-400g
- Peel is glossy, pebbly, somewhat thicker than hass, turns black towards ripening.

- Harvesting season coincides with main harvesting season of Hass
- Storage capacity is about 3 weeks at 5˚C and 95% relative humidity
Iriet
Iriet’ (previously 12-15) is the name given to an avocado (Persea americana Mill.) seedling selected in a breeding project conducted at the Akko Experiment Station in Western Galilee, Israel (Lahav et al., 1985). One of the objectives was to find a late cultivar, similar to ‘Hass’, but with larger fruit. In Spring 1973, ‘Hass’ trees were caged with beehives. The progeny fruits were harvested in Winter 1974 and seedlings were planted in Spring 1975. ‘Iriet’ was selected as the best cultivar from this population.
