| Research Abstract |
A long juvenile phase and high level of heterozygosity due to a strict gametophytic incompatibility have limited the parental combinations in pear breeding programs. Marker-assisted selection(MAS) is considered to be a powerful tool for increasing selection efficiency by identifying favorable genetic combinations. In this research, we have developed DNA markers for sucrose content responsible for taste improvement. Moreover, DNA markers linked to black spot and scab resistance were developed. These markers should be useful for the selection of seedlings with good taste and disease resistance.
