摘要新果实性状导入是HortResearch苹果育种计划的重要组成部分，旨在培育具有高消费者吸引力的新品种，红肉苹果育种是这一目标的重要组成部分。活跃的红肉育种始于1998年，HortResearch通过将低质量的红肉材料与高质量的品种和具有白色果肉的高级品种杂交而开始。红肉种质主要是从老品种衍生的自由授粉种子中培育出来的，并于20世纪90年代初进口到新西兰。到目前为止，在F1群体中已经产生了大约10,000株幼苗。改良的BC1群体是最近利用表现优异的F1家系中最好的红肉苗培育出来的。两种不同的红肉表型，推测命名为类型1和类型2，似乎受不同的遗传机制控制，在材料和分离家系中已被鉴定。讨论了利用表型分离和分子标记在改良红肉苹果果实品质和理解红肉性状遗传方面的进展。引言
Abstract Novel fruit trait introgression is an important part of the HortResearch apple-breeding programme in developing new varieties with high consumer appeal, and red flesh apple breeding is a major component of this objective. Active red flesh breeding began in HortResearch in 1998 by crossing low quality red-fleshed accessions with high quality cultivars and advanced selections that have white flesh. The red-fleshed accessions were mainly grown from open-pollinated seed that were derived from old cultivars and imported into New Zealand in the early 1990s. To date, approximately 10,000 seedlings have been produced in the F 1 populations. Modified BC 1 populations have recently been developed using the best red-fleshed seedlings from highly performing F 1 families. Two distinct red flesh phenotypes, putatively named Type 1 and Type 2, which appear to be controlled by different genetic mechanisms, have been identified in accessions and segregating families. Progress to date in improving fruit quality in red-fleshed apples and towards an understanding of the inheritance of the red flesh character, through the use of phenotypic segregations and molecular markers, is discussed.
