| Seed dressing by 3% thiophonate-methyl was conducted for the parents and the cross combination of temperate zone and
semitropical area germplast sweet corn. The comparison and genetic effect of their plant height and ear position were studied. The results showed that the plant height and ear position of sweet corn which were treated by 3% thiophonate-methyl got lower. The plant height of sweet corn got significant lower than the ear position, and the parent lines from semi-tropical germplasm were more sensitive than that from temperate zone. The analysis on genetic effect showed that there was significant positive relationship between plant height and ear position. The genetic for most of plant height (58.3%) shown as the supper dominance, and less of them (41.7%) shown as the part dominance. The genetic for less of ear position (33.3%) shown as the supper dominance, and most of them (66.7%) shown as the part dominance. |
