Se cuantificó la variabilidad genética de una muestra de 116 accesiones de habichuela P. vulgaris, cultivadas en centros primarios y secundarios de domesticación. Se evaluaron 18 descriptores morfo-agronómicos asociados con características de la planta, vaina y semilla. Mediante el análisis de la...

Five new marker genes in cassava are described; they control the following traits: chlorophyll production in seedlings, stem growth habit, stem collenchyma color, root parenchyma color, and leaf lobe shape (pandurate vs. normal). Names were proposed for each loci and dominant and recessive phenot...


Hershey, Clair H.Ocampo Nahar, César H.[New marker genes found in cassava]New marker genes found in cassava

Fifty-four accessions of Phaseolus vulgaris cultivated in Spain and representing a broad variability for this country, were studied together with 30 samples of wild forms of American origin. Two reference cultivars (from the Andes and Mesoamerica) plus two outgroups (P. coccineus and Vigna unguic...

Arachis pintoi, a wild perennial relative of the peanut, originated in Brazil, is of increasing importance to pasture improvement in the tropics. Its available genetic base, however, is very narrow, and intensive collection is being carried out. This study aimed to characterise the existing eight...

Isozyme variation was studied in 87 plants from 32 cultivated and wild accessions of banana passion fruit (P. tripartita var. mollissima, P. tripartita var. tripartita, P. tarminiana, and P. mixta), rosy passion fruit (P. cumbalensis), tin-tin (P. pinnatistipula), gulián (P. ampullacea), P. antio...
