T1 - Screening hybrid citrus rootstocks for resistance to Tylenchulus semipenetrans Cobb Y1 - 1997 SN - 0018-5345 UR - http://hdl.handle.net/20.500.11939/4698 AB - The response of 22 citrus hybrid rootstocks to a Mediterranean biotype of Tylenchulus semipenetrans Cobb was determined in a greenhouse test. Five of the 11 rootstocks with Poncirus trifoliata (L.) Raf in their parentage did not support nematode reproduction. However, rootstocks with Troyer citrange [Citrus sinensis (L.) Osbeck x P. trifoliata (L.) Raf] in their parentage were susceptible to the nematode. LA - en ER -
