Resumen
Pollen-fertility counts were made in five pineapple varieties and two selected seedlings, with the purpose of selecting the ones with high percentages of viable pollen grains as male parent plants. The varieties and selections used were Smooth Cayenne, Baron Rothschild, Red Spanish, Natal, Cabezona, 1B 13, and 7D 15. Among the varieties tested Baron Rothschild was the one with the highest percentage of viable pollen grains, followed by Smooth Cayenne. The rest were intermediate, except Cabezona which had the lowest percentage. The Cabezona variety is a triploid and triploid pineapples show, among other things, partial or complete sterility. Because of this it is a risk to use this variety as a male parent plant. Varieties with a high percentage of viable pollen should be used as male parent plants. Se informan aquí los resultados obtenidos en un estudio sobre el porcentaje de polen viable en dos selecciones y cinco variedades de piña. Se encontró quo la variedad Baron Rothschild tiene el porcentaje más alto de polen viable, seguida por la variedad Cayena Lisa. Las demás tienen un porcentaje intermedio con excepción de la variedad Cabezona, cuyo porcentaje es el más bajo. A base de estos resultados, se recomienda usar las variedades con los porcentajes más altos de polen viable, como plantas-padres.
