Possible explanations are considered. 1.

Co-ancestry values among parents used in crosses that originated these cultivars varied between 0 and 24%, with an average of 9%. In turn, the coefficient of parentage between cultivar pairs ranged from 7.45% to 56.65%, with an average of 20.09%. Cluster analysis using the coefficient of parentage as a measure of similarity indicated that Venezuelan varieties can be grouped into eight distinctive sets. It was found that 29 out of 44 SSR markers were polymorphic, originating 84 polymorphic fragments. Alleles generated by each primer showed between 2 and 6 bands, with average of 3.1. Multiple correspondence anal- yses showed that three eigenvalues explained 59% of variance allowing grouping of the studied varieties in six discrete sets. It was observed that molecular analysis is more precise and ...

The objective was to compare results of CALPUFF dispersion model with the registers of monitoring of the zone and to evaluate this dispersion model in two different topographic sites. El Hatillo mining area is located a few kilometres from the village of La Loma, where topographically flat area; the other areas (projects PLJ and Norcarbón) are located in the low mountain zone of the Perijá, near to the La Jagua of Ibirico village. For the introduction of the variable emission in the CALPUFF model, it was considered data as provided in the study of the Monterrey Institute of Technology (Huertas et al., 2012). Although the CALPUFF model is mostly recommended for long distances scenarios, there are exceptions for short distances scenarios, where the model is reliable to measure the behaviour of...
