Effect of plant density and tuber-seed size in basic seed production of creole potato «yema de huevo» cultivars (Solanum phureja luz. el Buk.)
The production ofbasic seed is a very important factor, for the seed production chain looking for high quality. The sowing density and the tuber size have not been researched for Solanum phureja Juz. el Buk. The evaluation ofthese factors was conducted at Experimental Center San Jorge - JCA. Randomized Complete Block Design with factorial array (4x3) was used in this assay. It was found that the distance among plants (15; 20; 25 and 30 cm) did not modify the seed production per unit of area. The tuber diameter between 1,27 to 2,00 cm., is the best choose in production of basic seed.

En Solanum phureja Juz. el Buk., los factores densidad de siembra y tamaño de tubérculo semilla óptimos para su producción no han sido evaluados hasta el momento. El presente trabajo tuvo como objetivo evaluar estos dos factores en condiciones de la Estación Experimental San Jorge JCA. La investigación se realizó bajo un Diseño en Bloques Completos al Azar con arreglo factorial 4 x 3. Se encontró que las distancias entre plantas evaluadas (15; 20; 25 y 30 cm) no afectan la producción de semilla por unidad de área y que la utilización de tubérculos-semilla entre 1,27 y 2,00 cm de diámetro es la más recomendada.
