Subsequently, the seeds were packed into Polypropylene woven bags and multilayer polyethylene lined hermetic (Super GrainPro (SGPr) and Purdue Improved Crop Storage (PICS)) bags and stored for 24 months. The combined analysis was done using a completely randomized design (CRD) with factorial arrangement replicated three times. The temperature of the refrigerator for cold storage was maintained at 5 \u00b13 \u00b0C with a relative humidity of 42 \u00b13%. In 2021, the annual mean temperature of ambient conditions ranged from 14.27 to 28.57 \u00b0C with relative humidity (RH) between 47% and 75%. In 2022, the annual mean temperature ranged from 13.97 to 29.51 \u00b0C with RH between 40.10% and 70.13%. The evaluation was conducted at Melkassa Agricultural Research Center.
