Screening and identification of cucumber germplasm and rootstock resistance against the root-knot nematode (Meloidogyne incognita).
Root-knot nematodes (Meloidogyne spp) are destructive agricultural pests that reduce the productivity of cultivated vegetables worldwide, especially when vegetables are cropped continuously in greenhouses. Cucumbers (Cucumis sativus L.), in particular, suffer extensive damage due to root-knot nematodes, and only a few wild species are known to be resistant. Grafting of cultivated plants to root...
متن کاملComparative Transcriptome Analysis Reveals a Preformed Defense System in Apple Root of a Resistant Genotype of G.935 in the Absence of Pathogen
Two apple rootstock genotypes G.935 and B.9 were recently demonstrated to exhibit distinct resistance responses following infection by Pythium ultimum. As part of an effort to elucidate the genetic regulation of apple root resistance to soilborne pathogens, preinoculation transcriptome variations in roots of these two apple rootstock genotypes are hypothesized to contribute to the observed dise...
متن کاملevaluation of safflower genotypes to find genetic sources of resistance to damping-off (pythium ultimum)
damping-off is an important disease of safflower in iran, that caused by pythium ultimum. because of its importance, fungi isolates were sampled from infected plants grown in research farm of the college of agriculture, gorgan university of agricultural sciences and natural resources, in 2006. also it has been proved that the disease caused by pythium ultimum. evaluation of seventeen safflower ...
متن کاملIs there meaningful plant resistance to diaprepes abbreviatus (Coleoptera: Curculionidae) in citrus rootstock germplasm?
Host plant resistance to the Diaprepes root weevil, Diaprepes abbreviatus (L.) was assessed for seedlings of 54 Poncirus trifoliata (L.) Raf. selections and two families of progeny from crosses between Citrus and P. trifoliata. Weight gain was consistently lower when larvae were reared in pots containing the progeny of Citrus reticulata Blanco 'Sunki' x P. trifoliata 'Flying Dragon' compared wi...
متن کاملimprovement of resistance to pythium ultimum in safflower by selection under field conditions
damage of the pathogens is one of the main limitations for cultivating and production of safflower. this study was performed to investigate reaction of safflower genotypes to pythium ultimum during 2009 and 2010 under field conditions. the study was done in two parts, selection and evaluation of parents (part 1; 2009) and evaluation of the progenies (part2; 2010). in the first year, the experim...
