Origin

The Genoa originated in Genoa, Italy. Parentage unknown from where it was taken to California during 1875. It is considered a Eureka type and is the principle variety grown in Argentina and Chile where it has achieved commercial importance. It was introduced into South Africa in 1998. Ownership; Open cultivar, (no Royalties).

Description

A dense tree of the Eureka type, earlier maturing and with one main set. The main crop is harvested during May/June in the Cooler Cape regions and approximately 4 weeks earlier in warmer areas.

Characteristics

The tree is vigorous with a spreading, dense growth habit. It is more cold resistant than Eureka. Like the Eureka it is substantially less thorny than Lisbon types. Fruit tends to be rounder than other lemons with a small shoulder. Rind colour is earlier than Lisbon. Seed counts can vary from nil to 6 per fruit in cold areas, but can be substantially higher in hot areas. Fruit size is larger than Eureka and Lisbon. It has a smooth to occasionally coarse, but thin, rind and sometimes high shoulders.

Rootstock
Options

Although it is described as being in the Eureka group, trials in South Africa have shown that it is compatible with trifoliate orange and its hybrids. Trial results have not shown any incompatibilities even on Swingle citrumelo, which is extremely incompatible with Eureka. Genoa trees on Swingle citrumelo and Rangpur Lime are smaller than rough Lemon or Volckamariana

Production
Tonnages of 90/tons on 5 year old trees have been recorded in Sundays River Valley. The production is concentrated into the early part of the Lemon season, a small percentage is left for the mid season pick.
General
The Genoa bears well, and is similar to Eureka in quality but tends to bear a concentrated crop in the early part of the lemon season. As a result it can be used in ones management to take off early, before the main season types such as Navel and Valencia. It is compatible with Citrange root stocks, as a result it can be used as an option in replant soils.
