Zonneveld, B.J.M. 2010. The involvement of Narcissus hispanicus Gouan in the origin of Narcissus bujei and of cultivated trumpet daffodils (Amaryllidaceae). Anales Jard. Bot. Madrid 67(1): 29-39.To investigate the origin of cultivated trumpet daffodils the genome size (2C-value) of more than 100 old and new cultivars were measured. A large number of concolored yellow tetraploid cultivars with large coronas seem to be derived from a doubling of chromosomes of a hybrid of the two species N. hispanicus Gouan and N. pseudonarcissus L. This can also still be recognized by the presence of a black spot at the top of the anthers in about 15 % of the tetraploid cultivars. Assuming N. pseudonarcissus as one of the parents of the allotetraploid cultivars, species of trumpet daffodils of section Pseudonarcissi investigated earlier were compared. Doubling of the nuclear DNA content of 23. Para investigar el origen de los narcisos trompeta cultivados se midió el tamaño del genoma (valor 2C) de más de 100 cultivares viejos y nuevos. Un gran número de cultivares tetraploides amarillos de color uniforme y con grandes coronas parecían derivarse de una duplicación de cromosomas de un híbrido de las dos especies N. hispanicus Gouan y N. pseudonarcissus L. Esto también se observa por la presencia de una mancha negra en la parte superior de las anteras en alrededor del 15 % de los cultivares tetraploides. Tomando a N. pseudonarcissus por uno de los parentales de los cultivares alotetraploides, se compararon especies de narcisos trompeta de la sección Pseudonarcissi que ya hubiesen sido investigados anteriormente. La duplicación del contenido de ADN nuclear de 23,8 pg de N. pseudonarcissus queda por debajo de los valores hallados en los narcisos trompeta. Se evaluaron otras especies de narciso trompeta de la sección Pseudonarcissi con una cantidad más alta de ADN nuclear complementaria, tales como N. hispanicus, con 25.8 pg, N. poeticus L., con 26 pg y el hexaploide N. pseudonarcissus ssp. bicolor (L.) Baker, con 67.7 pg (Zonneveld, 2008), entre otras. N. hispanicus, con 25.8 pg, se diferencia claramente de N. pseudonarcissus, con 23.8 pg, y también se acepta aquí como especie. El contenido de ADN nuclear de N. bujei (Fern. Casas) Fern. Casas, con 30 pg, se adecua al hibridismo (antiguo) para N. bujei entre N. longispathus Pugsley (36 pg) y N. hispanicus Gouan (25,8 pg). Los tetraploides con tépalos blancos y coronas amarillas pueden obtenerse con el cruzamiento entre N. pseudonarcissus diploide y el hexaploide y bicolor N. pseudonarcissus ssp. bicolor (L.) Baker.Palabras clave: Narcissus hispanicus, origen de los narcisos trompeta, origen de N. bujei.

The taxonomy of all species of Narcissus (Amaryllidaceae), an important horticultural crop, has not been investigated recently. As a new approach, genome size was determined by flow cytometry with propidium iodide from 375 accessions. The somatic nuclear DNA contents (2C) were shown to range from 14 to 38 pg for the diploids. Narcissus assoanus and N. gaditanus are, based on their nuclear DNA content, removed from section Apodanthi and placed in a new section Juncifolii. The different ploidy levels and species involved were entangled for N. ''fernandesii'' s.l. and a new allotetraploid form is named here. Section Pseudonarcissus was much more heterogeneous in nuclear DNA content than expected. Sixty-five accessions of N. pseudonarcissus possessed, with 23.7 pg, similar amounts of DNA. However, several species from this section were clearly distinctive in nuclear DNA content. It runs from the diploid N. primigenius with 21.7 pg to the also diploid N. nevadensis with 38.2 pg. Also N. abscissus and N. moleroi are with about 26 pg clearly different from N. pseudonarcissus. For the first time, in 11 accessions, hexaploidy was found in N. pseudonarcissus ssp. bicolor. A new section Nevadensis with 30-39 pg of nuclear DNA was split off from the section Pseudonarcissus with now 21-27 pg. A nonoploid N. dubius with 96.3 pg has by far the highest amount of nuclear DNA and can be calculated to have the highest ploidy ever reported in Narcisssus. The total number of Narcissus species was determined as 36, nine more than in Flora Europaea and they were divided up in two subgenera and 11 sections. Flow cytometry is shown to produce easily obtainable and original systematic data that lead to new insights. Genome size or C-value turns out to be one of the most salient features to define the status of the species in the genus Narcissus.
