More info on Holiday (originally XX3):
(Guat) 18-28 oz. fruit, pear shaped, green, dark yellow flesh, excellent flavor, medium pit, peels easily, glossy leaves, persea mite and thrip resistant, small tree with skirting shape, A blossom type. Produces well. Fruit is hidden inside tree. Holds well. Tree should be made available to the home gardener for it has the best fruit for a small tree that I am familiar with &is better that any available at nurseries at this time. Several trees at South Coast Research Station, Irvine, CA. (J.R.Frink 1998)This is a "grandchild" of the old "Murrieta Green" variety, which had a green, good-quality fruit, commercially too large; on a tree that was short & spreading-easy to pick,& to spray if necessary. XX3 is a good producer of rather similar large, fine, green fruits. The tree is almost unique among thousands of seedlings in that it tends to sprawl on the ground. This latter trait rules it out commercially-plus the over-sized fruit. Commercially, XX3 is without value. But, for backyard purposes it might be useful in CA. An avocado tree that remains very low could be desirable where a view, or sunlight transmission, is wanted; or, it could be grown on a (sturdy) fence. The green skin would be no detriment, & the large fruit size could be a non-commercial advantage. (Bergh 2000)
