For long term storage of seed, cryo-storage at -196°C is an effective approach among the ex-situ conservation methods. Even though the bitter gourd (Momordica charantia L.) seed has been classified as orthodox, various previous studies reported its sensitivity to sub-zero temperature. Hence, the present study was carried out to investigate the seed germination behavior of bitter gourd seeds after cryo-treatment with a view to test the cryo-fitness of the seeds. Results of seed viability experiments conducted in four germplasm lines such as Arka Harit, Co 1, Preethi and Bitter gourd long indicated significant differences in germination percentage in all the bitter gourd lines except Arka Harit.
