...otypes were evaluated as antixenosis, antibiosis and tolerance. These tested genotypes were (Pir Sabaq-2004, Atta-Habib, Saleem-2000, Serin-2010, Khyber-87, Sarhad-82, and Khushal-69) in three separate experiments. Antibiosis resistance was identified to R. padi in wheat cultivar (Serin-2010), where a minimum number of R. padi progeny were produced in 11.4 days. Wheat cultivar (Atta Habib) was found significantly susceptible to R. padi<...

...hese studies. Results of antixenosis tests (after 24 hours) showed that out of 20 only three lines i.e., V-01180, DN-47 and PR-84 were least preferred. Fifteen wheat lines/varieties were moderately preferred and only one germplasm line, V-9021 was highly preferred by this aphid. Observations after 48h showed that only two wheat germplasm lines, PR-84 and V-01180 were least preferred. Seventeen wheat lines/varieties were moderately preferred. There was only one...

...nisms of resistance like antixenosis, antibiosis and tolerance. Results indicated that the entry B-00080 had antibiosis and B-99036 was the tolerant one. So, on the basis of present studies the entry having high level of resistance against R. padi (B-99036) should be incorporated in the future breeding programmes.

...ents of resistance i.e., antixenosis, antibiosis and tolerance against greenbug, Schizaphis graminum (Rondani). NARC-09, Momal-2002, TD-1 and Zarlasta-99 were found resistant in seedling bulk test. Momal-2002 was the least preferred in antixenosis mechanism of resistance NARC-2009, Momal-2002 and Sulaman-96 were the least fecund in antibiosis mechanism of resistance and TD-1, NARC-2009 and Sussui were highly tolerant in tole...

...M. persicae. Significant antixenosis effects among the tested potato cultivars were observed while the different durations of M. persicae infestation on potato cultivars also displayed significant antixenosis effects against M. persicae during the spring and autumn experiments in 2016. During both experiments, Sarpo Mira displayed the lowest number of adults per plant on release of 100 and 200 adults per plant. Sarpo Mira sh...

... were carried out where, antixenosis experiment, comprised three levels; seedling, flowering and pod stage. In all the three stages, only genotype ‘KS-75’ proved as antixenosis resistant against the aphid compared to susceptible genotype Abaseen. The second experiment was performed to test antibiosis resistance against L. erysimi among the selected genotypes. During the antibiosis experiment different life table ...
