Hybrid breeding is an important method to improve the quality, yield and stress resistance of kiwifruit fruits. This study summarizes some new progress in intraspecific and interspecific hybridization of kiwifruit at present. Techniques such as embryo rescue, polyploid breeding, and molecular marker-assisted selection have all played a significant role in breeding. This study also elaborates on how genomic technology and phenomics tools make breeding more accurate and faster, and analyzes the common problems encountered in practice through typical breeding cases. This study aims to provide some ideas and references for the future improvement and innovation of kiwifruit hybrid breeding.
