TIQUE, José; CHAVES, Bernardo  and  ZURITA, Jorge Humberto. Agronomic evaluation of ten promissory CIP clones and two sweet potato (Ipomoea batatas L.) native materials. Agron. colomb. [online]. 2009, vol.27, n.2, pp.151-158. ISSN 0120-9965.

With the aim of rescuing the genetic variability of sweet potato (Ipomoea batatas), the agronomical performance of two native materials was evaluated and compared to that of ten clones classified as promissory at Centro Internacional de la Papa. Carried out along two crop cycles, the study took place in the municipality of Coyaima (Tolima - Colombia), with the participation of the members of the Buenavista Autonomous and Independent Indigenous Council, and the collaboration of the Consortium for the Support and Development of Cassava in Latin America and the Caribbean. The native materials were collected at local farms, and classified as 'Bonanza' and 'Sangretoro', which are their traditional indigenous names. The experiment was conducted under a completely randomized block design, with seven treatments (five CIP clones and the two regional varieties) and four repetitions. The results allowed quantifying the remarkably productive potential of cultivated sweet potato, and identifying very promissory materials that can therefore be incorporated to agricultural production models.
