Abstract
The TPS seedling tuber technique can be successfully adopted in developing as well as in developed countries as a standard agronomic system for potato production. Experimental work has been started in order to select the best parental lines and to evaluate the appropriate breeding schemes for the use of this technique in southern Italy. During 1989 48 true potato seed (TPS) families with different genetic backgrounds were tested for seedling tuber production and they produced a good yield. The seedling tuber families were tested for tuber production during 1990 by subdividing them in two size classes: 25mm-35mm and 35mm-45mm. The highest yield was attained by 4X x 2X families and the analysis of variance indicated significant differences with regard to tuber size and TPS families for both total and marketable tuber yield. This technique has significant potential for providing tubers for both the fall and winter crop in Italy.
Compendio
La técnica de los tuberculillos de semilla sexual puede ser adoptada exitosamente en los países del Tercer Mundo, al igual que en los países desarrollados, como un sistema agronómico estándar para la producción de papa. Se han iniciado trabajos de investigación para seleccionar las mejores líneas de padres y evaluar los sistemas de mejoramiento apropiados para la utilización de esta técnica al sur de Italia. Durante 1989, cuarenta y ocho familias de semilla sexual (TPS) con diferentes antecedentes genéticos, se probaron para la producción de tuberculillos de semilla sexual y las mismas produjeron un buen rendimiento. Las familias de tuberculillos fueron probadas para la producción de tubérculos durante 1990, dividiéndolas, por tamaño, en dos clases: 25mm-35mm y 35mm45mm. El mayor rendimiento fue obtenido por las familias 4X x 2X y el análisis de la variancia mostró diferencias significativas con respecto al tamaño de tubérculo y familias de TPS tanto para los rendimientos totales como para los comerciables. Esta técnica tiene en Italia un potencial significativo para proveer tubérculos tanto para la temporada de otoño como para la de invierno.
