Induced drought and salinity tolerance in the variants of Brassica campestris (L.).

Gopal Krishna Shukla

Abstract


The variants obtained from M2 generation of gamma irradiated toria varieties, T-9 and  PT303 of Brassica campestris (L.) were evaluated for drought and salt tolerance. Among them, variant TV4 of var. T-9 and the variants PD3 and PD4 of PT303 showed significantly higher antioxidant enzyme activities, proline content, relative water content percentage and yield per plant under these stress conditions. These variants appear more adaptive which may be assigned to their induced favorable genotypic alterations, and could be utilized for developing drought and salinity tolerant Brassicas.

Keywords


Brassica campestris (L.), drought, salinity, stress, tolerance, variants.
