QUINTERO, I et al. Evaluation of eleven promissory clones of potato (Solanum tuberosum L.) in Trujillo state. I. Growth, developing and yield. Rev. Fac. Agron. [online]. 2009, vol.26, n.3, pp.362-381. ISSN 0378-7818.

In order to evaluate the growth, development and yield of potato (Solanum tuberosum L.) clones 392639-1, 363258-44, 393160-3, 393258-16, 393180-10, 392634-5, 392639-41, 392639-17, 392636-9, 393194-1, the 393258-49 and "Andinita" variety, in "Marajabú" and "Páramo de Cabimbú", Trujillo State, Venezuela, an essay was carried out under a randomized blocks design with four replications, in a factorial arrangement 12x2. The growth habit, vigor, plant height, stems number by plant, yield and culture phases were evaluated. The quantitative variables were analyzed with the data processor SAS^®. The studied clones showed a habit of turgid growth, good vigor (6-8), suitable height, in "Marajabú" the families 392639 and 393258 showed a statistically similar yield to "Andinita" and showed to be more precocious than the control variety. In "Páramo Cabimbú" the clones 392639-1 and 362634-1 showed a significantly superior yield to the control and fulfilled their growth and development stages in smaller time than "Andinita". The characteristics shown by these clones outline them to be including in subsequent stages of evaluation and selection.
