Estimation of genetic diversity is an important factor in germplasm conservation and characterization. In rice breeding programs, genetic diversity information on specific regions of genome can be very useful for the application of marker assisted selection (MAS) and for gene mapping. A total of 152 rice lines were considered for breeding programs using microsatellites (SSR) technique. The tota...

Virtual Breeding Environments (VBEs) represent networks of disperse organisations, that will exploit specific collaboration opportunities through the creation of Virtual Organisations (VOs) supported by information and communication technologies (ICTs). This type of Collaborative Networked Organisation (CNO) should be able to generate different types of values (economical, social, cultural, etc...

Economic values for calving performance in first and later parities were estimated for the Piemontese cattle. Calving performance is a threshold trait usually recorded using a scoring system with categories corresponding to the rate of difficulty. In the Piemontese breed five categories were adopted (from unassisted to foetotomy). A normal underlying distribution with thresholds corresponding t...
