Average analysis to compare the value of each dose of irradiation to duration grown, number of tubers, stem diameter, bulb length, and tuber weight in the MV1 and MV2 can be seen in Table 3. Effect irradiation dose on the variable factor of tuber production be showed of MV1 and MV2. The yam accession BDa–15 in MV1 generation has the tuber production higher average 6.7 kg/plant, followed by BDa–11 and BDa-–35, respectively 3.7 and 3.6 kg/plant. The generally doses of gamma irradiation higher cause production tuber decline. Production of yam MV2 average is above 0.5 kg / plant, but well below average tuber production MV2 generation. It is thought likely caused by heavy rainfall in the growing season MV2 generation.
