Résumé
This research has the objective of evaluating the 10 varieties of native potato under two hydroponic and conventional production systems to obtain pre-basic seed that was carried out in the facilities of the Engineering in Agricultural Production and Marketing Degree belonging to the Universidad Mayor de San Andrés located in the city of Viacha, department of La Paz, Bolivia, under controlled conditions with the de Biodiversity Conservation project for the production of pre basic seed of native varieties, in the communities of the Murillo and Omasuyos del department of La Paz ", with a completely randomized design with bi factorial, with 20 treatments, with factor A = Varieties (Lipapala, Surimana, Churi Sapallu, Choq´epithu, Ch’iyara imilla, Allqa ajawiri, Imilla negra, Sapallu , Kusillo, Luk´i) and factor B = substrates (hydroponic and conventional). In the variables of height Sapallu with 100.15 cm obtained better results, and in diameter of stem per plant Allqa Ajawiri with 5.30 mm was also the highest, both in conventional substrate. In the weight variables, the Allqa Ajawiri variety bagged 17.21 g the highest weight and number of tubers, the Surimana variety 5.18 tubers per plant also had the best results in the conventional substrate. The B / C ratio, presents values greater than 1 in the cases, that the production of prebasic seed is profitable for the farmer, obtaining greater benefits with the Allqa ajawiri variety, it has a B / C ratio of 2.57 with the variety Kusillo has a B / C ratio of 2.41 Bs with a gain of 2.14 Bs from the conventional system and from the hydroponic system, only two varieties were profitable, the Allqa ajawiri, it has a B / C ratio of 1.14 and 0 , 92 Bs respectively, and with Sapallu it has a B / C ratio of 1.46 Bs with a profit of 0. 46Bs
