Objective of this research was to evaluate field corn inbreds for baby corn production. Diallel cross among 10 Kasetsart inbred lines (Ki); i.e., Ki20, Ki21, Ki32, Ki34, Ki35, Ki36, Ki37, Ki38, Ki43, and Ki44 were employed by using Griffing (1956) Method IV Model I. All possible crosses were evaluated in 1992 late rainy season at Suwan Farm. The results showed that inbreds possessing positive general combining ability effects (GCA) with significant difference from zero for unhusked ear weight were Ki20, Ki32, and Ki44. And only the single cross of Ki20 x Ki32 gave higher significant yield than Suwan 2(S)C7. For husked ear weight, inbreds having positive GCA with significant difference from zero were Ki20, Ki21, Ki32, and Ki37. And the hybrids that gave significant yield than Suwan 2(S)C7 were Ki20 x Ki32, Ki20 x Ki43, Ki21 x Ki32, and Ki32 x Ki37. For good ear weight, Ki20 and Ki36 gave positive GCA with significant difference from zero. Seventeen hybrids gave higher significant yield than Suwan 2(S)C7. The highest-yielding hybrids were Ki20 x Ki37 and Ki36 x Ki37.
