MEJORAMIENTO GENÉTICO DE ALSTROEMERIA EN LA ARGENTINA: OBTENCIÓN DE HÍBRIDOS A TRAVÉS DE RESCATE DE EMBRIONES PAKOCA, C. BUGALLO, V. FACCIUTO, G. The Alstroemeria genus comprises about 90 species restricted to South America, 10 species are distributed in Argentina. Its cultivation has grown in popularity due to the variety of colors and post-harvest quality of its flowers. The objective of this work was the study of the compatibility between A. psittacina and 9 alstroemeria varieties and the adjustment of the embryo rescue technique. The study of the growth of the pollen tube allowed to detect different situations according to the varieties. The number of germinated embryos and the obtaining of normal seedlings varied with respect to the variety and time to rescue. In the case of crosses with “Belvedere”, the highest number of germinated embryos was produced at 14 days post pollination (DPP), for “Cartagena” at 7 DPP and for “Costa Azul”, no significant differences were detected between both times. Seedlings were obtained in the crosses with “Belvedere”, “Cartagena”, “Costa Azul”, “Himalaya” and “Virginia”. The highest reproductive efficiency was in “Costa Azul” being 6,6 and 8,4 for rescues at 7 and 14 DPP, respectively. These results will allow the advancement of the Alstroemeria breeding program to obtain Argentine varieties. El género Alstroemeria comprende cerca de 90 especies restrictas a América del Sur, de las cuales, 10 se distribuyen en la Argentina. Su cultivo ha crecido en popularidad debido a la variedad de colores y calidad postcosecha de sus flores. El objetivo de este trabajo fue el estudio de la compatibilidad entre A. psittacina y 9 variedades de alstroemeria y el ajuste de la técnica de rescate de embriones. El estudio del crecimiento del tubo polínico permitió detectar distintas situaciones según las variedades. El número de embriones germinados y la obtención de plántulas normales varió respecto a la variedad y al tiempo al rescate. En el caso de los cruzamientos con “Belvedere”, la mayor cantidad de embriones germinados se produjo a los 14 días post polinización (DPP), para “Cartagena” a los 7 DPP y para “Costa Azul” no se detectaron diferencias significativas entre ambos tiempos. Se obtuvieron plántulas en los cruzamientos con “Belvedere”, “Cartagena”, “Costa Azul”, “Himalaya” y “Virginia”. La eficiencia reproductiva mayor fue en “Costa Azul” siendo 6,6 y 8,4 para los rescates a 7 y 14 DPP, respectivamente. Estos resultados permitirán el avance del plan de mejoramiento de Alstroemeria para la obtención de variedades argentinas.
