Special Issue Information

Dear Colleagues,

Cucurbitaceous crops, including watermelons (Citrullus lanatus), melons (Cucumis melo), cucumbers (Cucumis sativus), and pumpkin and squash (Cucurbita spp.) crops, are one of the most genetically diverse plant families and contain several health-promoting substances and play a vital role in sustaining human life. With the worsening of the global environment, the fast growth of the global population, and the improvement in people's living standards, the market demand for high-quality cucurbitaceous crops in large quantities is expanding dramatically. There is a wide genetic variation among cucurbitaceous crop genetic resources for diverse qualitative and quantitative attributes for effective variety design, product development, and marketing. The rapid development of omics techniques and bioinformatic algorithms provides convenience for functional gene mining and breeding innovations. Utilizing the abundant germplasm and improved varieties basic for the development of Cucurbitaceous Crop industrialization.

Over the past decade, germplasm and breeding innovations in cucurbitaceous Crops have exhibited rapid development. Research and application areas are mostly concentrated on the development of a new variety of resources by conventional and modern breeding methods, like BSA, Mutmap, EMS, etc., and the obtainment of new germplasms by genetic transformation and gene editing technology in cucurbitaceous crops is also an effective and efficient approach.

This Special Issue on “Germplasm and Breeding Innovations in Cucurbitaceous Crops” welcomes the submission of review and research papers or short communications on the following topics: germplasm, genome sequence information, evolutionary relationships, and functional genes associated with important agronomic traits in cucurbitaceous crops. Advances in these research fields are applicable to basic research in cucurbitaceous crops, and promote the applications of these resources and methods.

A half-diallel cross study of seven melon inbred lines was carried out. The seven parents and their 21 F1 hybrids were evaluated for precocity of maturity, average weight per fruit, and fruit quality (fruit size, rind thickness, and soluble solids). The Diallel analysis was investigated for breeding values of these melon genotypes via general and specific combining ability, relationships between general and specific combining ability, and heterosis for the evaluated traits. The analysis of variance of the traits evaluated indicated highly significant differences among genotypes, suggesting the presence of adequate genetic variation for breeding. Additive genetic effects were most important with respect to fruit weight, while genetic dominance and epistasis effects mainly controlled fruit quality traits (fruit size, rind thickness, and TSS). Parent 1 (P1) and parent 3 (P3) had significant positive general combining ability effects for fruit weight. Also, P3 had positive general combining ability effects for fruit length and diameter, and cavity diameter. P3 was found to show maximum significant GCA in the desirable direction for all the traits except for TSS. Evaluation of heterosis (%) revealed that hybrid P1 × P3 can be considered as the best-performing hybrid for average fruit weight, TSS, and precocity, which also exhibited the highest positive and significant SCA effect for these traits. These results suggested that, among the melon genotypes studied, there is the potential to generate superior new varieties in hybrid production. Full article
