Traditional selection based on genetic merit calculated from phenotypic and pedigree information has been tremendously effective at improving production in dairy cattle. Hypothetically, genetic improvement could be accelerated even further for yield and other economically important traits by directly selecting upon the genetic differences underlying the phenotypes. To elucidate these genetic di...

Despite a favorable business model, genomic selection is still not a popular tool for genetic improvement of Nelore cattle in Brazil mainly due to the lack of a costeffective strategy for its application. Different independent Nelore breeding programs have already developed prediction equations for usual and difficult/expensive to measure traits. Unfortunately, some programs are using genomic p...

4. The cross between both control lines is higher in egg production than, and similar in total egg mass and feed efficiency to, the industry L x A crosses, indicating that little or no genetic improvement has been made in these characters in some commercial breeding flocks in the past 10 years. This aspect of the above experiment in particular needs to be confirmed. If true, it will indicate an...

Genetic Programming (GP) has long been applied to several SBSE problems. Recently there has been much interest in using GP and its variants to solve demanding problems in which the code evolved by GP is intended for deployment. This paper investigates the application of genetic improvement to a challenging problem of improving a well-studied system: a Boolean satisfiability (SAT) solver called ...

Information on the genetic identity and interrelationships of different Morus spp. genotypes is essential for their proper conservation and utilization. Hence, the present investigation was undertaken with genetically more reliable DNA markers to study the genetic relationship among eleven selected genotypes of mulberry collected from Japan, India and Italy. Using ten RAPD and ten ISSR primers,...

While seed source selection is an important initial step in the genetic improvement of Christmas trees, continuously returning to seed collections from natural stands precludes any further improvement in genetic quality. In addition, the genetic variation within most seed sources is tremendous and varies from year to year. In order for the Christmas tree industry to move past the current level ...

Maternal cytoplasmic inheritance may cause an upward bias in heritabili ty estimates from daughter on dam regression. Inaccurate evaluations of bulls or dams of future sires would result if such estimates were used in genetic evaluation. Expected genetic selection differential for bulls would be overestimated, but genetic gain would be little affected by incorrect heritabili ty estimates. Genet...

Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...
