El objetivo de este trabajo fue determinar el comportamiento del perímetro escrotal (PE) en sementales Siboney de Cuba y estimar sus componentes de (co)varianza y parámetros genéticos mediante diversas metodologías. Para ello inicialmente se analizaron 1477 registros de perímetro escrotal de 790 sementales que nacieron entre 1980 y el 2005, con mediciones testiculares entre 1981 y el 2007; pro ...

Cuban Miocene vertebrates

MacPhee, R. D. E. et al. [2003]

"This report summarizes the results of paleontological and geological investigations carried out during the 1990s at Domo de Zaza, a late early Miocene vertebrate locality in south-central Cuba. Paleontologically, the most important result of fieldwork at Zaza was the first discovery of terrestrial mammals of Tertiary age in Cuba. Three terrestrial mammal taxa are now known from this locality- ...

Following the deep crisis at the beginning of the present decade, several measures were adopted by the Cuban Government to guarantee food production and, in more general terms, economic survival of the country. One of such measures was the conversion of the agricultural system from a high input model to a more sustainable, almost organic one. Within this context the development of alternative ...

An analysis of the diversity among avocado varieties cultivated in Cuba was undertaken based on agro-morphological traits and DNA markers. In order to determine phenotypic diversity of the collection as well as the phenotypic traits contributing to avocado race classification, 22 agro-morphological traits were used in a Principal Component and Classification Analysis. To compare the efficiency ...

Propolis has been known for its healing properties for centuries and today many propolis products are available commercially. However, propolis collected from different geographic regions of the world may have different composition and may vary in activity. The lack of commonly accepted standardization and quality control procedures is an obstacle to the wide use of propolis in the mainstream ...

Isozyrne patterns of esterase (EST), malate dehydrogenase (MDH) and superoxide dismutase (SOD) were used to determine the species of thirteen Meloidogyne isolates from populations originating from India (6), Venezuela (5), Cuba (1) and Egypt (1) and collected from different hosts. It was possible to characterize most of the populations tested as M. incognita and M. javanica, but only a part of ...

Diaphania hyalinata (L.) is the key pest of the cucurbitaceas; however, the specifications of their biology and etology are ignored in the Northern areas of Las Tunas province, where pumpkin (Cucurbita moschata Duch.) is a cultivation of economic interest whose yields are affected by the pest. During 3 years, the general characteristics of the life cycle and behaviour were observed to define, ...

Molecular approaches were used to characterize mango varieties and initiate the establishment of a molecular linkage map. The 30 most important mango cultivars commercially grown in Cuba were studied with respect to their genetic relationships by DNA marker analysis. A dendrogram based on a total of 199 polymorphic markers distinguished germplasm introduced from the Philippines from all other ...

A total of 62 guava genotypes assembled in the Cuban guava germplasm collection at Alquízar were characterized by molecular analysis applying the AFLP DNA marker technique. Phylogenetic relationships were established by the UPGMA method and the results compared to the classification according to available records of collection and pedigree. Furthermore, three guava mapping populations were pro ...

A total of 49 accessions assembled in the Cuban guava germplasm collection at Alquizar (Havana province) were characterized by phenotypic descriptors and AFLP DNA marker analysis. The morphological and agronomic characterization by the UPOV descriptors resulted in the identification of elite varieties with respect to characters of economic interest. This will permit an adequate parental select ...
