Walnut (Juglans regia L.) is a diploid (2n = 32), deciduous, monoecious, and generally open-pollinated tree with nuts of high nutrient content. In this study, the phenological differences, genetic diversity, population structure Kaman-1 its 79 progenies obtained by open pollination were characterized ISSR primers some important traits. As result observations, it was determined that differ signi...
Although self incompatibility in walnut has not been reported, but the dicogamy limits self pollination of walnut cultivars. As the density of female flowers produced by the tree is low, if a high fruit set occurs, yield especially in terminal bearing cultivars will not be high. So breeding of a pollinizer cultivar with proper pollen shading period is highly necessary for increasing fruit produ...
RFLP markers were used to investigate genetic diversity among California walnut (Juglans regia) cultivars and germplasm collected worldwide. Sixteen of 21 RFLP markers were polymorphic in the 48 walnut accessions tested. RFLP markers were useful for identifying walnut cultivars. All genotypes were heterozygous at ≈20% of the loci for both California and worldwide germplasm. California walnut ge...
Field studies focused on evaluating the efficacy of new bactericides for reducing the incidence of walnut blight, verification of XanthoCast as an effective model for forecasting the disease, and on evaluating host resistance among walnut genotypes under ambient and simulated-rain conditions. In studies with new bactericides in plots in Butte, Tehama, Solano, and Fresno Co., no material evaluat...
