摘要

无籽西瓜的生产依赖于三倍体栽培或植物生长调节剂的应用。然而，三倍体品种的染色体不平衡和应用生长调节剂对食品安全的担忧等挑战阻碍了这一进程。为了应对这些挑战，我们通过破坏双受精过程，培育出了二倍体无籽西瓜的有性和无性繁殖诱导系。这种创新方法成功诱导出了不同品种的二倍体无籽西瓜。

A sexually and vegetatively reproducible diploid seedless watermelon inducer via ClHAP2 mutation

Seedless watermelon production relies on triploid cultivation or the application of plant growth regulators. However, challenges such as chromosomal imbalances in triploid varieties and concerns about food safety with growth regulator application impede progress. To tackle these challenges, we developed a sexually and vegetatively reproducible inducer line of diploid seedless watermelon by disrupting the double fertilization process. This innovative approach has enabled the successful induction of diploid seedless watermelon across diverse varieties. A study developed a universal seedless watermelon inducer line using CRISPR/Cas9 to knock out the HAP2 gene, simplifying the breeding process and addressing food safety concerns. This method may also apply to other crops such as cherries or grapes.
