Among six linseed genotypes tested under field condition on a zinc deficient (avail. In. 0.5 mg kg−1) calcareous soil, Jawahar variety emerged as the most susceptible to In deficiency while NP 5 was found relatively a tolerant variety. Subhra was found to be highest oil yielder which produced about 100 kg more oil than the relatively tolerant variety NP 5 when In was not a limiting factor. Based on seed and oil yield response, the relative susceptibility of the linseed varieties was rated as: Jawahar > T-397 = Subhra = BAU-188 > RAULD-82-19 > NP-5.
