Abstract: In this paper,spider mite and aphid resistance were studied in 16 core accessions of L.pennellii,the wild relative of tomato.In open field experiment,10 accessions set fruits and only 7 accessions set seeds.Spider mites resistance was evaluated by inoculating in lab.The result showed that 15 accessions were resistant to spider mite,but LA1920 was highly susceptible.Out of 15 accessions,one was immune,and 12 highly resistant,and 2 resistant.By field monitor,it was found that all the 16 accessions were highly resistant resources to aphids.2 accessions were immune to aphids,and 14 accessions were highly resistant.

Key words: Tomato, L.pennellii, Spider mite, Aphid
