The Amazon river dolphin, genus Inia, is endemic to the major river basins of northern South America. No previous studies have focused on the genetic structure of this genus. In this work, 96 DNA samples from specimens of this genus were collected in the Orinoco basin (four rivers), the Putumayo ...

(Cetacea: Iniidae)]Molecular identification of evolutionary significant units in the Amazon river dolphin Inia sp. (Cetacea: Iniidae)

Plant-to-plant phenotypic variation has been observed within accessions of S. capitata maintained at the Centro Internacional de Agricultura Tropical (CIAT) since shortly following introduction. A small experiment was conducted to determine the potential importance of natural outcrossing as a cau...

Autor: Davis, J.H.C.

Some basic definitions on genetics in relation to bean cultivation are presented in which a description is given on how to use this information in a breeding program. Examples are given on the management of quantitative characters (yield and plant height) controlled by different genes and qualita...


Davis, J.H.C.[Conceptos basicos de genetica de frijol]Conceptos basicos de genetica de frijol

The concept of plant genetic variability is studied as well as how it should be treated and presented to the researcher, especially in the management of bean genetic resources. Given the spread of some crops such as soybeans and pods, searching for variability in the available genetic resources f...


Debouck, Daniel G.[Patrones de diversidad genetica en Phaseolus : hechos, ideas e implicaciones]Patrones de diversidad genetica en Phaseolus : hechos, ideas e implicaciones

A report is given on the 4 cultivated species of the genus Phaseolus, studying geographic distribution, taxonomy and morphology, agronomic characteristics and germplasm collection. The areas where Phaseolus vulgaris is extensively cultivated are North, Central and South America, Europe and E. Afr...


Hidalgo, R.Song, L[Diversidad genetica en especies de Phaseolus]Diversidad genetica en especies de Phaseolus

The morphological and agronomic aspects of the species Phaseolus vulgaris, Phaseolus lunatus, Phaseolus coccineus subesp. coccineus and Phaseolus acutifolius var. latifolius are described and the general characters of wild species are also presented. A list of wild species is included along with ...
