Walnut Improvement Program ( Usda - Ars
نویسنده
چکیده
The primary goal of the Walnut Improvement Program, which was initiated in 1982 as a cooperative effort between USDA-ARS and U.C. Davis, is to develop germplasm with increased resistance or tolerance to the two major diseases limiting commercial production of Persian walnuts. These are the blackline and the Phytophthora root and crown rot diseases. Also under the auspices of this program are the projects involved with the development of new sources of germplasm (see Plant Regeneration fram Walnut Protoplasts Endosperm and Embryo) and selection of new varieties (see Evaluation and selection of seedling walnuts at U.C.-Davis).

Plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. Photoautotrophic and photomixotrophic systems could diminish these problems. The purpose of this study was to increase the chlorophyll...
