| Description | Gabriel, J., Herbas,J., Salazar, M., Ruiz, J., Lopéz, J., Villarroel, J and Cossio, D. 2004. Participatory Plant Breeding: A New Challenge in the Generation and Appropriation of Potato Varieties by Farmers in Bolivia. Working Document No. 22. PRGA Program. Cali, Colombia. 22 p.Experiments on participatory plant breeding (PPB), financed by the CGIAR Systemwide Program on PRGA and Papa Andina, were carried out with the active participation of farmers from the communities of Piusilla-San Isidro and Compañía Pampa of the Morochata Region in Bolivia. Nine men and eight women farmers were involved. Conventional breeding takes many years of experimenting to generate varieties for a broad range of environments. It is complicated by the need to develop varieties for particular niches. These varieties must be similar to those already being used, but more productive, more resistant to biotic factors such as late blight (Phytophthora infestans) and false root-knot nematode (Nacobbus aberrans), and more acceptable to local markets. The farmers who participated in the experiment, unique for Bolivia, call themselves potato breeders and, jointly with the plant breeders, have generated varieties similar to the cv. Waych’a which is the most widely consumed cultivar in Bolivia, but resistant to late blight (or t’octu in Quechua). The joint efforts between farmers and plant breeders resulted in 12 varieties with superior yield (10-25 t/ha) to that of Waych’a (5 t/ha) and possessing the agronomic traits and qualities of Waych’a, the main parent. Three of the varieties showed potential for the potato chip industry, with little burning at the edges, uniform frying, little absorption of oil, being neither porous nor greasy, and possessing good-sized tubers that are larger than those of either Waych’a or Robusta. |
