<p>La evaluación de 22 colectas y trestestigos de fríjol arbustivo procedentes del banco de germoplasma de Corpoica en Mosquera, Colombia, permitió seleccionar variables que discriminan la variabilidad existente e identificar las colectas sobresalientes por parámetros morfológicos cuantitativos y componentes de rendimiento. Se seleccionaron las variables de mayor heredabilidad representadas por coeficiente de repetibilidad r&gt;l (Goodmany Paterniani,1969), de las 24 variables cuantitativas en estudio, l4 cumplieron esta condición, las variables descartadas fueron las del estado de plántula, área foliar y rendimiento. El análisis por componentes principales de las 14 variables retenidas mostró cómo los tres primeros componentes explicaron eI 88.49% de la variación total, donde los caracteres: días a floración, días a cosecha, peso de 100 semillas, número de semillas por vaina, ancho y longitud de la vaina, altura de cobertura, número de nudos, y longitud de epicotilo e hipocotilo fueron los que mas aportarona dicha variación. Las colectas del acervo Mesoamericano: Antioquia 2l, Cauca 34 y Tolima 16, y del acervo Andino: Perú5 (PorotoLargo) y Cundinamarca 148; presentaron el mejor comportamiento agronómico y alta variabilidad genética, por lo cual se consideran de importancia en la conservación de su variabilidad y como posibles progenitores.</p><p align="center"> </p><p><strong>Selection of quantitative variables and classification of 22 accesions of shrubby bean (Phaseolus vulgaris L. )</strong></p><p>Evaluation of 22 collections and three tests of shrubby beans Phaseolus vulgaris L. From the germ plasm bank of the Colombian Corporation of Agricultural Research (Corpoica), allowed the selection of variables to discriminate the existing variability and to identifier the besta ccesions by means of quantitative morphological parameters and yield components. Variables with high heredabilitywere chosen based on repetibility coefficients graterthan one (Goodman and Paterniani,1969); and as a result, 14 varieties out of 24 were selected. Analysis conduced by principal components showed that the first three components explained 88.49% of the total variation. Characters such as days to flowering, days to harvest, weight of 100 seeds, seeds for pod, length and wide of pod, canopy cover, number of knots, length of epicotile and hypocotile explained most of the total variation collections from the mesoamerican pool :Antioquia 2l (Tenzano), Cauca 34 and Tolima 16, aswell as the Andeanpool : Perú5 { PorotoLargo) and Cundinamarca 148, presented the best agronomic performance and high genetic variabiliti and as a result, these collections were considered outstanding as source of genetic variability and for improvement programs.</p>

Disappearance of old cultivars, including dry and snap bean (Phaseolus vulgaris L.) has been accelerated in last five to six decades, which mainly led to great genetic impoverishment. For all the humanity and its future, particularly is important the maintenance and evaluation of old cultivar?s seeds. The research presented in this paper has been conducted on the territory of southwestern Fruska gora Mt. Of the collected samples of field and vegetables crops, as well as wild plants on the mountain, 13 accessions of snap bean and 21 accessions of dry bean have been analyzed in this paper. Seed color, seed shape, 1000-seed mass and phaseolin type was determined for all the accessions. Seeds of collected bean and snap bean accessions were predominantly white and cylindrical in shape. Mass of 1000 seeds ranged between 104,90 g and 634,96 g. T phaseolin type dominated, while S type of phaseolin was present in six bean and in two snap bean accessions.

Đã điều tra lectin của 6 giống đậu cô ve thấy rằng cả 6 giống đều có hoạt tính lectin trong đó giống đậu cove hạt trắng dạng bụi (white bean core bush type white seeds) có hoạt tính lectin mạnh nhất, đặc biệt đối với hồng cầu trâu, bò, lợn. Lectin của 6 giống này đều không có biểu hiện đặc hiệu nhóm máu. Lectin đậu cove hạt trắng dạng bụi hoạt động tốt nhất ở nhiệt độ 300C – 400C, pH 6,8 – 7,6. Các đường α-D-glucose, α-D-galactose, D-mannose, D-fructose, D-saccharide,  D-lactose, D-arabinose và D-manitose ở nồng độ 0,05 – 0,1 M có tác dụng kìm hãm hoạt tính của lectin đậu cove hạt trắng dạng bụi. Lectin này cũng bị kìm hãm bởi protein của một số huyết thanh người và động vật (trâu, bò, lợn). Đã tinh sạch lectin đậu cove hạt trắng dạng bụi có độ tinh sạch gấp khoảng 52 lần so với dịch thô ban đầu. Trên gel polyacrylamide thấy xuất hiện 5 band có khối lượng phân tử trong khoảng 30 – 97 kDa.
