영문 초록

A maize inbred, IK was developed by authors for developing maize hybrids with tillers. The inbred line has two to three tillers per plant under normal plant densities. The general combining abilities of the IK line has been studied and reported. But the very basic genetic nature of the tillering behavior of the IK line was not known. Therefore, the objectives of the study were to differentiate the tillering nature of the line from those of other tillering maize lines from different sources and to test allelic relationship with Tlr line reported by Neuffer and finally to map the gene responsible for the tillering of the IK line under the assumption that the gene concerned is monogenic in effect and non-allelic with previously reported Tlr gene. From the study, authors found that the tillering nature of the IK line was completely different from that of other tillering lines from Mexico and U.S., and the tillering of the IK line is controlled by single dominant gene. The gene found was temporally designated as Tlr2. Authors were also able to identify chromosomal location of the gene by means of reciprocal translocation sets of chromosome 9 involving waxy(wx) gene and the gene TIr2 was found to be located on the long arm of chromosome 3.
