Abstract:
A field experiment was carried out to screen the coriander germplasm for drought tolerance at various Locations in Horticultural College and Research Institute, TNAU, Coimbatore. Preliminary screening was done with 240 accessions and 50 accessions were selected based on yield performance along with check CO (Cr) 4 and were raised in main field in a Randomized Block Design in three replications. The crop was grown purely under rain fed condition. Biochemical parameters were measured during crop growth. A considerable reduction was noticed in biochemical components such as soluble protein contents and NRase activity. In contrast, proline content was significantly increased under water deficit. The expression of characters under water deficit revealed the tolerant nature of coriander accessions. ACC 18, followed by ACC 87 is thus grouped as drought tolerant accessions and ACC 145, ACC 202, ACC 201, ACC 230 as drought susceptible accessions.
