Leaf-miner, Phytomyza horticola Gour. is a serious pest of peas, Pisum sativum L. in the Punjab. In an AII India Co-ordinated Trial three leaf-miner resistant cultivars (P 29, P 201 and P 402) of field peas were compared with a local cultivat (T 163) during 1972–73 and 1973–74. Cultivars P 29 and P201 proved most promising as they were least susceptible to the incidence of the pea leaf-miner. The infestation of leaves varied from 0 1 to 4.0 per cent in both the trials against 11.6 to 6.9 per cent in P 402 and 4.3 to 31.7 per cent in the standard variety T 163.
