Zusammenfassung: | The invention discloses development and application of a molecular marker for rapidly identifying the length of a fruit base of a pomelo fruit, and belongs to the technical field of fruit appearance quality detection. The invention provides a target genome InDel fragment closely linked with the appearance change of pomelo fruits. The nucleotide sequence of the target genome InDel fragment is as shown in SEQ ID No. 1. A set of simple and rapid PCR markers is developed according to the target genome InDel fragment, PCR amplification is performed through the primer pair F and R, and the length of the pomelo fruit base can be identified. The marker is low in cost and high in accuracy, early selection of the length of the fruit base can be achieved in the pomelo seedling stage, and the breeding efficiency is improved.
本发明公开了一种快速鉴别柚果实果基长度的分子标记的开发与应用,属于果实外观品质检测技术领域。本发明提供了一种与柚果实外观变化紧密连锁的目标基因组InDel片段,所述目标基因组InDel片段的核苷酸序列如SEQ IDNo.1所示。本发明根据所述目标基因组InDel片段开发了一套简单、快捷的PCR标记,通过引物对F、R进行PCR扩增,能够鉴别柚果基长短。本发明所述标记成本低、准确率高,可在柚苗期实现 |
