- Abstract:
- ... ‘Biloxi’ tetraploid southern highbush blueberry is a new cultivar developed and released by the Agricultural Research Service of the U.S. Department of Agriculture breeding programs in Beltsville, MD, and Poplarville MS. Plants of “Biloxi’ are upright, vigorous and productive. The fruit ripens early, has medium size, with good color, firmness, stem scar, and flavor. Although ‘Biloxi’ is predominan ...

- Abstract:
- ... The Agricultural Research Service, USDA, has developed and released five dark-leaf crape myrtles: âEbony Fireâ, âEbony Flameâ, Ebony Embersâ, âEbony & Ivoryâ, and âEbony Glowâ. The cultivars are predominantly Lagerstroemia indica in heritage. As with most hardy crapemyrtle cultivars, selections are generally top hardy in USDA Hardiness Zone 7 and root hardy to Zone 6 if properly ...

Fifteen microsatellite simple-sequence repeat (SSR) loci were used to genotype 58 accessions of cultivated olive, Olea europaea L. ssp. europaea var. europaea, from two collections of 19th to 20th century plantings in Arizona and California, in order to examine genetic diversity and structure within and among collections. These collections are Lotusland Gardens in Santa Barbara, CA, and the Arbore ...

Traditional tree breeding programs face the challenges of long generation time and significant expense in land and personnel resources. Avocado selection and breeding can be more efficient and less expensive through the development of molecular markers for the estimation of germplasm genetic diversity, marker-assi ...

Russian wheat aphid (RWA) (Diuraphis noxia Kurdjumov) infestations of barley (Hordeum vulgare L.) cause chlorotic leaf spotting and streaking and prevent unrolling of leaves, which traps spikes and reduces grain yield. Resistant accessions identified in the USDA-ARS National Small Grains Collection (NSGC) were used to develop adapted, resistant germplasm and cultivars. This study identified loci a ...

Two cultivars of fresh market tomato [Oregon Spring (OS) and Red Sun (RS)] were each grown in two high tunnels at Beltsville, MD covered with a contrasting material of similar thickness (0.152 mm) and durability (4-year polyethylene). One covering material (Tyco Tufflite IV) transmitted ambient solar UV radiation from 290 to 400 nm (designated+UV) while the other material (Dura-Film Super 4) block ...

- Abstract:
- ... No-tillage (NT) crop production practices have been continuously maintained at four sites in Ohio for more than 25 yr. The original experiments involving NT were designed to determine how much tillage was required to produce crops with satisfactory yields and how tillage and rotation interact to effect crop yields, especially corn (Zen mays L.). Long-term effects of NT on crop yields and soil prop ...
