It’s a labor of love to ensure the healthy delivery of cute, cuddly puppies. They don’t “just happen.” Several factors play into successful?dog reproduction?and dog breeding programs, including knowledge about basic reproduction, reproductive health for dogs, whelping and post-natal care.? At BioZyme®, our team adores dogs of all breeds, colors and sizes. We realize ...
Although fungicides can kill spores and stop transmission, fungicide treatments are neither cost-effective nor ecologically sustainable. "A viable alternative is to selectively breed or genetically modify wheat for resistance to WYMV," Dr Pourkheirandish said. ...
Not everyone will agree with my arguments in this article. However, I’m tired of hearing complaints about current sow mortality rates and general agreement that additional research is needed in gilt development; yet remain disappointed in the lack of tangible, practical strategies that producers can take home and implement at the ‘slat level’ to make meaningful changes in their ...
First, of course, is overall egg production numbers. Different breeds of chicken produce eggs in varying numbers and with varying consistency. Before you select a breed, look into this and find out not only how often the hens will lay eggs but for what duration. ...
The main innovation components are to: use selective breeding to increase harvesting yield, and apply ground-breaking direct seeding on specially designed substrates to save time, energy and money in the hatchery phase. ...
The approach included use of genomic selection, the concept of using genome-wide dense genetic maps to predict the genetic merit of individual animals, and enhance selective breeding efficiency. ...
It has a dedicated program called MARINER to fund projects that are working on various components needed to jump-start a new seaweed-energy industry: technology and systems for cultivation and harvesting, transportation, selective breeding, and more. For example, MARINER includes a specific category for projects on aquatic monitoring—seaweed farms could ...
Feed your fish several times a day, depending on the fish species. Suitable Fish Species Selecting the right fish species is very important to maximize the profits of the fish farming business. Select those breeds that are in high demand and at high prices in the local market. ...
“In the multitude of different environments that exist in nature, the uncertainty is too great to make a reliable prediction of what the impact would be,” he says. GE or Selective Breeding? Does the fast growth of AquAdvantage salmon justify taking on these unknown risks? Scientists point out that today’s selective ...

On his seed farm, he had managed to double the salt-tolerance limit of two of the varieties — Lal Getu and Sada Getu — by meticulous selective breeding of the crop at different salinity levels. Most traditional rice varieties, including the ones Deb carried that day, are adapted to local climates and regions. ...

It continues with farmer-participation in breeding and selecting improved varieties, a process that can take several years. ...
The objective of this review was to determine the relationship between grain yield, harvest index, and stover yield to illuminate the potential for increasing both grain and stover yield through breeding. In contrast to what has been observed in other crops, gains in maize grain yield over time in the U.S. Corn Belt have been accompanied by increases in stover yield. Where ...
Studies have shown that heterosis decreased 25%/50 yr, 10%/60 yr, and 35%/100 yr. Natural selection and artificial selection by plant breeders for adaptedness have increased parental inbred and hybrid seed yields, whereas percentage heterosis decreased. ...
Despite widespread use of early generation testing and selection (EGT) in breeding for self-pollinated crops, its effectiveness remains largely an unresolved issue. This issue is tackled here using elaborated genetic models that enable genetic and nongenetic effects to be assessed for the effectiveness of EGT in terms of (i) the selection ...
Selection among breeding lines has been widely used to identify important cultivars and favorable alleles for adaptation, and resistance to abiotic and biotic stress. The objective of this work was to study the variability among common bean breeding lines selected from ancestral landraces, to evaluate the reaction of these lines ...
Knowledge in this area could aid in future germplasm maintenance activities, provide additional information in the area of N. tabacum population genetics, and assist in selection of materials for breeding or genetic investigations. To this end, 702 N. tabacum accessions from the U.S. ...
Knowledge of target environments in breeding programs is important to better direct the development of germplasm. The objectives of this study were to identify associations among barley (Hordeum vulgare L.) growing environments to identify mega-environments to select the best locations to breed barley. Twenty-seven years of grain yield data from ...
The content of salicylic glycosides in the bark is differential and depends on genotype, therefore continued selection is necessary to find high-yielding crop varieties of S. purpurea with a high salicylic glycoside content of the bark. ...
However, our knowledge of the genetic factors underlying oleate variation in soybean seeds remains incomplete, hampering the use of marker-assisted selection in soybean breeding programs. We used a whole-genome scan approach to identify oleate quantitative trait loci (QTLs) in a soybean population segregating for oleic acid content and a cognate segregating ...
(HOM) population, KYHO, was developed across 10 generations by selective breeding. The objectives of this investigation were to evaluate the effects of selection for kernel oil on correlated traits and measure the genetic variance of kernel oil content (KOC). ...
