Percentage of viable seeds in spikes of hybrid plants resulting from the backcross of deletion line 7C12 (types 1 and 2 combined) and translocation lines 12A5, 12H3 and the WST lines onto wheat cultivar Huntsman. An average percentage was calculated for each hybrid type. Three batches of plants were sown, except for the WST lines for which only two batches were sown. Percentages were adjusted according to the average spike fertility for self-pollinated parental lines for each batch to take environmental conditions into account
