Resumen: "Cucurbita pepo is an economically important crop, which consists of culti- vated C. pepo ssp. pepo, and two wild taxa (C. pepo ssp. fraterna and C. pepo ssp. ovifera). We aimed at understanding the domestication and the diversity of C. pepo in Mexico. We used two chloroplast regions and nine nuclear microsatellite loci to assess the levels of genetic variation and struc- ture for C. pepo ssp. pepo’s landraces sampled in 13 locations in Mexico, five improved varieties, one C. pepo ssp. fraterna population and ornamental C. pepo ssp. ovifera. We tested four hypotheses regarding the origin of C. pepo ssp. pepo’s ancestor through Approximate Bayesian Computation: C. pepo ssp. ovifera as the ancestor"
