The experiment was conducted in three parts (I) Biochemical characterization of bottle gourd seed. (II) Seed priming effect of melatonin and water deficit stress and (III) differential gene expression study. Phytochemical, biochemical and molecular characterization was carried out in seeds of ten various bottle gourd genotypes/varietiesviz., (1) GABGH-1, (2) ABG-1, (3) Pusa Naveen, (4) ABG-11-17, (5) ABG-11-23, (6) Santosh, (7) DBG-5, (8) Samrat, (9) NDBG-104 and (10) Arka Bahar.EnglishThesis
