Abstract:
A laboratory experiment was laid out in Completely Randomized Block Design consist of 50 tomato genotypes were tested in roll towel method and impose the salinity level of 0mM, 20mM, 40mM, 60mM, 80mM, 100mM and 120mM with three replication. In the investigation work were carried out at HC & RI, TNAU, Coimbatore. Significant variations were observed in seed germination, seedling growth and root characters and the data were statistically analyzed by ANOVA. In the result of the present study showed that, 38 tomato genotypes were germinated under moderate salinity level of 80mM. The highest seed germination percentage (66.66), shoot length (6.60) and root length (7.70) were observed in LE-1respectively. Whereas, LE-14 observed in highest seedling length (13.56), seedling fresh weight (0.247), seedling dry weight (0.04) respectively. Fresh seedling tolerant index were noticed in IIVR-88783 (94.3) and dry seedling tolerant index (251.3) in Khasi genotype of tomato. The lowest seed germination and seedling parameters were recorded Pharna Baskar under moderate saline condition. The seven level of salinity treated (0mM to 80mM) with tomato genotypes, seed germination, seedling parameters well in moderate saline level (80mM) and least performance were observed in 100m and 120mM respectively.
