ABSTRACT:
SUMMARY OF THE INVENTION
The new
Juglans regia
Walnut Tree of the present invention was created at Davis, Calif. during 1991 by a controlled cross of the ‘Howard’ cultivar U.S. Plant Pat. No. 4,405) and the ‘Purpurea’ cultivar (non-patented in the United States). See U.S. Plant Pat. No. 4,405 for the ancestry of the ‘Howard’ parent. The ‘Purpurea’ parent used in the cross also identified as ‘RX1088’ and was obtained from the Walnut collection of E. Germain (Institut National de la Recherche Agronomique, Station de Recherches d'Arboriculture Fruitiere, Bordeaux, France). The Kernels of the ‘Howard’ parent bear a typical seed coat that is amber or light amber. The kernels of the ‘Purpurea’ cultivar possess a reddish-brown seed coat. The parentage of the new cultivar can be summarized as follows:
‘Howard’בPurpurea’.
Seeds from the cross were collected and planted and the resulting trees were carefully observed. A single plant of the new cultivar was selected in view of its highly distinctive combination of characteristics. This selection initially was designated ‘91-75-15’.
It was found that the new
Juglans regia
cultivar of the present invention exhibits the following combination of characteristics:
(a) Forms jumbo-sized walnuts with little size variation in a given harvest which possess strong thick well-filled shells and easy to remove kernels,
(b) Forms kernels which display a distinctive red-purple pellicle,
(c) Bears fruit laterally, and
(d) Yields a walnut crop that commonly can be harvested from a young tree prior to that of the ‘Chandler’ cultivar (U.S. Plant Pat. No. 4,388) at Davis, Calif.
The new cultivar of the present invention has been propagated by grafting at Davis, Calif. on ‘Paradox’ hybrid rootstock. The distinctive characteristics of the new cultivar have been found to be stable and are transmitted from one generation to another following such a sexual propagation.
The new cultivar of the present invention has been named the ‘Robert Livermore’ cultivar. Rober Livermore was a supporter of the Walnut Improvement Program at the University of California for many years and is honored through the naming of this plant.
