Abstract
Salinity constitutes a principal abiotic constraint on agricultural productivity in arid and semi-arid regions worldwide. The experiment was conducted at College of Horticulture and Forestry, Jhalawar during 2022-23 to estimate the effect of various salinity regimes on germination and seedling growth. Fourteen accessions of fenugreek were evaluated in RBD with three replications at three salinity regimes (0.00%, 0.50% and 0.75 % NaCl). Pooled analysis of variance was indicated significant differences among the accessions, salinity and accession × salinity for the seed vigour traits. Seed vigour traits were showed significant positive correlation with each other. Based on Salt tolerance indices and principal component analysis, RMt-305, RMt-351, AFg-2, RMt-303 and GM-2 were noticed tolerant among the accessions. These accessions can be utilized in breeding programmes for developing climate resilience varieties with better germination and seedling growth.
