    • Abstract


      Mucuna pruriens is a well-recognized agricultural and horticultural crop with important medicinal use. However, antinutritionalfactors in seed and adverse morphological characters have negatively affected its cultivation. To elucidate the geneticcontrol of agronomic traits, an intraspecific genetic linkage map of Indian M. pruriens has been developed based on amplifiedfragment length polymorphism (AFLP) markers using 200 F F$_{2}$ progenies derived from a cross between wild and cultivatedgenotypes. The resulting linkage map comprised 129 AFLP markers dispersed over 13 linkage groups spanning a total distanceof 618.88 cM with an average marker interval of 4.79 cM. For the first time, three QTLs explaining about 6.05–14.77%of the corresponding total phenotypic variation for three quantitative (seed) traits and, eight QTLs explaining about 25.96%of the corresponding total phenotypic variation for three qualitative traits have been detected on four linkage groups. The mappresented here will pave a way for mapping of genes/QTLs for the important agronomic and horticultural traits contrastingbetween the parents used in this study.
