摘要:

分子标记辅助选择(MAS)可以显著提高无核葡萄的育种效率,加快育种进程。本研究基于VviAGL11基因的单碱基突变位点(Chr.18:26889437A/C))开发了KASP_VviAGL11VviAGL11_410标记,并以SSR标记p3_VvAGL115U_VviAGL11标记作对比,分别在101份葡萄品种和81份葡萄F1杂交株系进行检测。结果认为KASP_VviAGL11VviAGL11_410均检测出A等位基因时与葡萄无核性状紧密关联,且准确率为100%,而p3_VvAGL115U_VviAGL11由于容易产生假阳性导致准确率偏低。然后通过评估不同标记使用的技术优缺点,明确了KASP_VviAGL11标记具有更加简单、经济、高效、精确的优势。最终,本研究优化了以KASP_VviAGL11标记为核心的无核葡萄分子标记辅助选择育种过程,为加快无核葡萄新品种培育进程提供关键技术支持。

Abstract:

Molecular marker-assisted selection (MAS) can significantly accelerate and improve the efficiency of the breeding process in seedless grape cultivars.  In this study, we developed the KASP_VviAGL11 and VviAGL11_410 markers based on a single nucleotide polymorphism (SNP) site (Chr18: 26889437 (A/C)) of the VviAGL11 gene, and compared them with previously reported SSR markers p3_VvAGL11 and 5U_VviAGL11 by testing 101 cultivars and 81 F1 hybrid progenies.  The results showed that both of the proposed markers obtained 100% accuracy rates in detecting allele A, which was closely associated with the seedless trait in grapes, while p3_VvAGL11 and 5U_VviAGL11 had lower accuracy rates due to their tendency to produce false positives.  After careful evaluation of the technical advantages and disadvantages associated with these markers, we concluded that KASP_VviAGL11 was superior in terms of simplicity, cost-effectiveness, efficiency, and accuracy.  Thus, we optimized the process of molecular MAS for seedless grapes, focusing on the KASP_VviAGL11 marker as a central component, to provide key technical support for the development of new seedless grape cultivars.
