Seed potato production 2004.

摘要

German seed potato production in 2004 was similar to the total potato production values. Average yields were 43.1 t/ha on 292 800 ha. The final registered seed potato production area was 18 928 ha, up 7% from the previous year. Following field inspection, 18 648 ha were certified, up 8% from the previous year. Major production increases were in the main seed potato regions of Lower Saxony, Mecklenburg-Vorpommern, Bavaria and Schleswig-Holstein. A total of 283 different potato varieties were available for seed in 2004. The leading varieties (>1%) made up 53% of the total area. The main varieties are Agria (1236 ha), Kuras (1217 ha), Marabel (809 ha), Cilena (712 ha), Princess, Karalena, Saturna, Quarta, Solara, Tomensa, Elkana, Granola, Satina, Linda, Albatros, Secura, Fasan, Milva, Selma and Adretta (184 ha). Among the new varieties tested were Valetta, Juwel, Fruhgold, Aktiva, Vienna, Toccata, Octavia, Omega, Ramses, Caruso, Opal, Tizia, Aspirant and Maxi. Results of virus assessments showed low levels of virus infection. Because of the low price levels in 2004, a cyclical low demand for seed potatoes in 2005 is expected..
