ABSTRACT
A lab experiment was conducted at the Department of Seed Science and Technology, College of Agriculture, University of Agricultural Sciences, Raichur to study the methods to overcome dormancy in linseed genotypes. Ten linseed genotypes were studied in the present investigation. Various physical and chemical treatments were imposed to break the dormancy of freshly harvested seeds. The KNO3 treatment at 0.5 % showed significantly the highest mean germination (82.40 %), seedling vigour index (1549), seedling dry weight (43.7 mg), speed of germination (22.59), Among the genotypes, Suyog recorded maximum germination (75.14 %), seedling vigour index (1243), seedling dry weight (41.2 mg), speed of germination (19.97), Hence, KNO3 treatment at 0.5 % is effective for breaking dormancy in freshly harvested linseed genotypes.
Key words: Dormancy, KNO3 , Linseed, Genotypes, Breaking methods
