2. Evaluation of inbred lines extracted from early versus late cycles of Suwan 1.
2.1. In comparing yields of single crosses derived from inbreds extracted from SUWan
1(8) cycles 4, 5 and 6, 8uphanviwat et a7. (1987) found that the inbred lines which showed good
general combining ability in cycle 4 were Ki3, Ki9, and Ki17; those in cycle 5 were KCP 1-5-85-2­
21, KCP 1-5-85-5-5-1, and KCP 1-5-85-40-2-3; those in cycle 6 were KCP 1-6-85-349-1-1, KCP
1-6-85-424-1-3 and KCP 1-6-85-695-1-2.
