Phytophthora cinnamomi causes a severe root rot in avocado, Persea americana. Breeding tolerant rootstocks is thought to be the most promising method for phytophthora root rot disease control but breeding avocado is challenging. The avocado flowering syndrome (synchronous protogynous dichogamy), combined with high flowering and low fruit set, render controlled pollination exceedingly difficult....

Previous research has shown that parity (P) 4 progeny have greater weaning weights and decreased microbial diversity. The objective of this experiment was to evaluate litter performance, passive immunity, and fecal microbiota among P1 (n = 56) and P3 (n = 49) dams and their progeny. Blood samples were collected from P1 and P3 dams on d 90 and 114 of gestation and d 0 of lactation and from their...

This experiment was conducted to compare meat quality and carcass composition of a diverse sampling of sheep breeds. Finnsheep, Romanov, Dorper, White Dorper, Katahdin, Rambouillet, Suffolk, Texel, Dorset, and Composite (½ Columbia rams to 1/4; Hampshire × 1/4; Suffolk) rams were mated to mature Composite ewes. Lambs (n = 804) were reared intensively, grain finished, and serially harvested over...

This experiment was conducted to compare meat quality and carcass composition of a diverse sampling of sheep breeds. Finnsheep, Romanov, Dorper, White Dorper, Katahdin, Rambouillet, Suffolk, Texel, Dorset, and Composite (1⁄2 Columbia rams to 1⁄4 Hampshire × 1⁄4 Suffolk) rams were mated to mature Composite ewes. Lambs (n = 804) were reared intensively, grain fi nished, and serially harvested ove...

The present study aimed to assess impact of selection based on microsatellite-genotypes at ADL0176 and the association MCW0044 located chromosome number-2 with growth layer economic traits in RIR chicken could reveal when sire component influenced progeny-birds different genotypes microsatellites. DD, EE CC/AD-genotypes microsatellite had corresponding higher BW28, BW40 EW40 progeny than other ...

Background: Radon, an invisible, odorless, heaviest (nine times heavier than air) and radioactive gas is an aberration (the only gas in the long decay chain of heavy metal elements). It is ubiquitously present in dwellings and in the environment. Humans receive the greatest radiation dose in their homes. That's where they spend most time - typically 70%, more for small children. Recent worldwid...

The use of open-pollinated seeds from seed orchards is a common strategy for the deployment genetically improved eucalypts, including Eucalyptus globulus, an important pulpwood tree in many temperate climate areas. However, quality can be affected by rate selfing and to lesser extent contamination pollen outside orchard. Inbreeding between related parents especially self-crosses known cause dim...
