Selection for verticillium wilt resistance in potato breeding populations derived from four cross types
Verticillium wilt (VW) is one of the important yield-limiting diseases for potato production. To develop resistant clones, the potential for early generation selection was studied using three basic selection methods, individual, family, and within family selection, for two clonal generations. A total of 152 clones were derived from four cross types (2x · 2x, 2x · 4x, 4x · 2x and 4x · 4x). Clone...
متن کاملInduced resistance in potato plants against verticillium wilt invoked by chitosan and Acibenzolar-S-methyl
Verticillium wilt of potato is a major limiting factor in potato production caused by Verticillium dahliae. The objective of this study was to evaluate the efficacy two elicitors including Acibenzolar-S-methyl (ASM) and Chitosan as plant activator in controlling of potato verticillium wilt in vitro and greenhouse conditions. ASM and chitosan were tested in vitro using Potato dextrose Agar (PDA)...
متن کاملGenetic dissection of Verticillium wilt resistance mediated by tomato Ve1.
Vascular wilt diseases caused by soil-borne pathogens are among the most devastating plant diseases worldwide. The Verticillium genus includes vascular wilt pathogens with a wide host range. Although V. longisporum infects various hosts belonging to the Cruciferaceae, V. dahliae and V. albo-atrum cause vascular wilt diseases in over 200 dicotyledonous species, including economically important c...
متن کاملIdentification of Molecular Markers Linked to the Verticillium wilt Resistance Gene Homologue in Potato (Solanum tuberosum L.)
Verticillium wilt is a vascular disease predominantly caused by the soil-borne fungi Verticillium dahliae and Verticillium albo-atrum. Most of the commercial potato cultivars grown in the USA are susceptible to Verticillium, resulting in significant crop losses. Development of new cultivars with resistance gene(s) against the pathogen can be assisted with molecular marker technology that allows...
متن کاملThe influence of Pratylenchus penetrans on the incidence and severity of verticillium wilt of potato.
The influence of Pratylenchus penetrans on the incidence and severity of Verticillium wilt was examined in the potato cultivars 'Kennebec', 'Katahdin', and 'Abnaki'. Single-stem plants were grown in soil maintained at a temperature of 22 +/- 1 C. Axenically cultured nematodes were suspended in water and introduced to the soil, at a rate of ca 5,000/25.4-cm pot, through holes made around each st...
