A HASS OPEN-POLLINATED PROGENY SET

The windbreak and rootstock plantings jointly provided about 630 Hass seedlings derived from open-pollination. A few of these have died. Many of those along the southeast fence are too crowded by the alternating trees of another species to have any chance of setting fruit. The windbreak avocados near the S.C.F.S. buildings were, unfortunately, removed. Fruiting of many of the remainder has been delayed by the need for severe pruning of the windbreak trees; the avocado is not really adapted to strong air movement, and tree breakage and bending has had to be controlled by extensive pruning. Still others, in the rootstock section, have failed to set any fruit in spite of apparently ideal circumstances.
