The cytogenetic relationships in the species of Cucurbitaceae are becoming immensely important to answer questions pertaining to genome evolution. Here, a simplified and updated data resource on cytogenetics of Cucurbitaceae is presented on the basis of foundational parameters (basic, zygotic and gametic chromosome numbers, ploidy, genome size, karyotype) and molecular cytogenetics. We have revised and collated our own findings on seven agriculturally important Indian cucurbit species in a comparative account with the globally published reports. Chromosome count (of around 19% species) shows nearly three-fold differences while genome size (of nearly 5% species) shows 5.84-fold differences across the species. There is no significant correlation between chromosome numbers and nuclear genome sizes. The possible trend of evolution is discussed here based on molecular cytogenetics data, especially the types and distribution of nucleolus organizer regions (NORs). The review supersedes the scopes of general chromosome databases and invites scopes for continuous updates. The offline resource serves as an exclusive toolkit for research and breeding communities across the globe and also opens scope for future establishment of web-database on Cucurbitaceae cytogenetics.

关于葫芦科细胞遗传学的批判性评论以及印度分类群的更新

 葫芦科物种的细胞遗传学关系对于回答与基因组进化有关的问题变得非常重要。在此，基于基本参数（基本、合子和配子染色体数、倍性、基因组大小、核型）和分子细胞遗传学，介绍了葫芦科细胞遗传学的简化和更新数据资源。在与全球发布的报告进行比较的过程中，我们修订并整理了我们自己对七种具有重要农业意义的印度葫芦科品种的发现。染色体计数（约 19% 的物种）显示出近三倍的差异，而基因组大小（近 5% 的物种）显示出 5.84 倍的差异。染色体数目和核基因组大小之间没有显着相关性。这里根据分子细胞遗传学数据，特别是核仁组织区 (NOR) 的类型和分布，讨论了可能的进化趋势。该审查取代了一般染色体数据库的范围，并邀请范围进行持续更新。离线资源作为全球研究和育种社区的独家工具包，也为未来建立葫芦科细胞遗传学网络数据库开辟了空间。
