Primer group of KASP molecular marker closely linked with major QTL (quantitative trait loci) of grain weight per ear of wheat and application of primer group

The invention discloses a primer group of a KASP molecular marker closely linked with major QTL of wheat grain weight per ear and application of the primer group, and relates to the technical field of molecular marker assisted breeding, the molecular marker is KASP-AX-109431092, the primer group comprises three primers, and the nucleotide sequences of the three primers are shown as SEQ ID NO.10, SEQ ID NO.11 and SEQ ID NO.12 respectively. The molecular marker provided by the invention can assist in screening of wheat with high grain weight per ear in wheat breeding, can save the breeding cost and improve the breeding efficiency, and has important significance for high-yield breeding of wheat. 本发明公开了一种与小麦单穗粒重的主效QTL紧密连锁的KASP分子标记的引物组及其应用，涉及分子标记辅助育种技术领域，该分子标记为KASP-AX-109431092，其引物组共包含3条引物，其核苷酸序列分别如SEQ IDNO.10、SEQ ID NO.11和SEQ ID NO.12所示。本发明提供的分子标记在小麦的育种中能够协助进行高穗粒重小麦的筛选，可以节约育种成本，提高育种效率，对于小麦高产育种具有重要意义。
