Identification of a candidate gene controlling semi-dwarfism in watermelon, Citrullus lanatus, using a combination of genetic linkage mapping and QTL-seq

Artificial neural networks and genetic dissimilarity among saladette type dwarf tomato plant populations

“…The potential of dwarf plants is clear for the provision of gene introgression aimed at several agronomic, morphological, and nutritional advantages and a broad spectrum of pest resistance ( Table 1 , Table 2 ). Plants with shorter internodes have been used in breeding programs for various crops, and improvements have been reported in yield and plant architecture when a dwarf parent is used ( Finzi et al, 2017 , Wu et al, 2018 , Cho et al, 2021 ). The dwarf tomato plant populations obtained in this study exhibited short internodes and could be viable alternatives for increasing the yield of future hybrid tomato plants, and thereby obtain plants with more compact architecture that will facilitate management and harvest activities ( Frasca et al, 2014 , Sun et al, 2019 ).…”

Genetic Analysis of Fruit Quality Traits in Sweet Watermelon (Citrullus lanatus var. lanatus): A Review

“…Quantitative trait loci conditioning organic acids, VOCs, flesh and cell-wall structural compounds are yet to be discovered and mapped in watermelon. NGS technology combined with sequencing-based gene mining strategies such as bulk segregant analysis (BSA), bulked segregant analysis sequencing (BSA-seq), and genome-wide association study (GWAS) have been successfully used in gene discovery associated with agronomic and horticultural traits in watermelon ( Wei et al, 2017 ; Dong et al, 2018 , 2021 ; Ren et al, 2018 ; Zhu et al, 2019 ; Gimode et al, 2020 ; Cho et al, 2021 ; Liu et al, 2021 ; Wang C. et al, 2021 ; Wang et al, 2022 ). These technologies are useful for mining QTL linked to organic acids, VOCs, flesh and cell-wall structural compounds in watermelon.…”

Retrospective Genetic Analysis of Qualitative and Quantitative Traits in Sweet Watermelon (Citrullus lanatus var. lanatus): A Review

“…The deletion of a single nucleotide of the gene Cla010337 causes the development of shorter watermelon plants [84]. Quantitative analysis revealed segregation ratios of 3:1 and 1:1 in the F 2 and backcross populations, suggesting that reduced plant height is controlled by a single recessive or dominant gene [82,85,86]. Cho et al [86] identified the gene CICG09G018320, which encodes an ABC transporter, determining shorter watermelon plants in progenies derived between dwarf (Bush Sugar Baby) and normal (PCL-J1) watermelon cultivars.…”

Internode length is a secondary trait that influences plant height in watermelon.…”
