Climate change, a pressing global concern, poses significant challenges to agricultural systems worldwide. Among the myriad impacts of climate change, the cultivation of kiwifruit trees (Actinidia spp.) faces multifaceted challenges. In this review, we delve into the intricate effects of climate change on kiwifruit production, which span phenologic...
This study aimed to assess the characteristics of fruit quality and seed formation resulting from pollination byfour different pollen donors: ‘SKK2’, ‘Deliwoong’, ‘Pohwa’, and ‘Chieftain’. The objective was to identify the mosteffective pollen donor for yielding commercially viable fruits in two cultivars of kiwifruit (Actinidia chinensis var.chine...
Gene-based markers are valuable tools in breeding programs due to their direct linkage to traits of interest. In dioecious plants, such as kiwifruit (Actinidia spp.), sex-discriminating markers can shorten the breeding cycle by enabling the selection of preferred sexes at the juvenile stage. To develop a gene-based sex-discriminating marker, resequ...
This study sought to evaluate fruit and seed characteristics after pollination by four pollen donors, denoted here as ‘SKK2’, ‘Deliwoong’, ‘Pohwa’, and ‘Chieftain’, and to select the best pollen donors for producing commercial fruits from the domestic kiwifruit (Actinidia chinensis) cultivars ‘Haeguem’ and ‘Redvita’. The fruit setting rates of ‘Hae...
This study investigated pollen application methods for artificial pollination in tetraploid kiwifruit cultivars ‘Halla Gold’ and ‘Sweet Gold’ grown in a nonheated plastic-film house in Jeju, Korea. Pollen of the hexaploid cultivar ‘Bohwa’ (A. chinensis var. deliciosa) bred in Korea was used for artificial pollination. We examined the effect of repe...
The state of weather conditions is an important factor that directly or indirectly affects thequantity and quality of fruit during the process of its cultivation. Unlike in the past, due to the currentlywider range of fluctuations in the minimum temperatures during the period from March to April, fruitsthat bloom earlier in the season often suffer...
The influence of the preharvest application of chitosan on physicochemical properties and changes in gene expression of ‘Garmrok’ kiwifruit during postharvest cold storage (0 °C; RH 90–95%; 90 days) was investigated. Preharvest treatment of chitosan increased the fruit weight but had no significant effect on fruit size. The chitosan treatment suppr...
Genotyping-by-sequencing (GBS) was used to investigate the genetic diversity and population structure of kiwifruits (Actinidia spp.). Using single nucleotide polymorphisms detected by GBS, phylogenetic tree and population structure were constructed for 89 kiwifruit accessions including Korean native A. arguta. The kiwifruit accessions were clearly...
