Summary: This study evaluated the genetic inheritance of growth traits, identified suitable deployment zones, and determined optimal triploid hybrids for different experimental sites. Significant clonal and site effects as well as clone-site interactions were observed for all growth and yield traits. The Weixian, Gaotang, and Yanzhou sites were suitable deployment zones, while Zhengzhou, Taiyuan, Pinggu, and Xiangfen sites were optimal for deployment. Yield performance and stability varied significantly among all triploid hybrids, highlighting the need for a suitable clone that performs well across all sites. The triploid hybrid clone S2 was identified as the ideal genotype based on both performance and stability.

Summary: This study quantified and compared the changes in concentrations of 17β-estradiol (E2), testosterone (T), and 11-ketotestosterone (11-KT) in the gonads and plasma of diploid and triploid gibel carp. It was found that the concentrations of these hormones mainly depended on the reproductive phase rather than ploidy. Gibel carp, regardless of ploidy, had an extended period of reproduction, and the differences in sex hormone concentrations between 2n and 3n females may contribute to the coexistence of gynogenetic C. gibelio females and sexual diploids.

Summary: In this study, triploid, mitogynogenetic (doubled haploid; DH) and meiogynogenetic brook trout were produced to assess the efficiency of these technologies and the potential susceptibility of chromosome set manipulated individuals for spinal disorders. The highest survival rates were observed among triploid brook trout, while DHs showed the highest mortality. Additionally, significantly increased malformation rates were observed in meiogynogenetic and mitogynogenetic individuals compared to non-manipulated diploids. The study discusses genetic factors and side effects of HHP shock that may impact survival rates and prevalence of skeletal deformities in chromosome set manipulated brook trout.

Summary: Through cold shock, it is possible to efficiently produce sterile triploid hybrids, and analysis shows that the abnormal development of these sterile fish's gonadal tissues may be due to disorders in gamete generation during meiosis.

Summary: Research shows that in the hybrid clone line of red crucian carp and common carp, there is a failure in chromosome pairing in the fertilized eggs, leading to sterility. However, after a long period of inhibition, the chromosome number doubles and successfully forms paired chromosomes and synaptonemal complex. This study further reveals the mechanisms of meiosis in hybrids.

Summary: This study investigated the triploid hybrid vigor in biomass-related willow traits and analyzed its relevance to the control of biomethane production. The results showed that the triploid hybrids had larger leaves, higher growth rates, and different hormone concentrations compared to their parental cultivars. Utilizing triploid hybrid vigor can expand the cultivation of short rotation energy trees and contribute to renewable energy production.

Summary: This study induced diploid meiotic and mitotic gynogenesis in Barbonymus gonionotus through cold shock treatment for production of monosex all-female population. Karyotype analysis showed the ploidy status of the offspring, and DNA microsatellite analysis revealed that the gynogenetic offspring possessed maternal alleles only, with paternal inheritance inhibited. The gynogens could be converted into sex-reversed males (XX) through masculinizing hormone treatment.

Summary: Clinch Dace is a newly discovered fish species with a limited and scattered distribution in the upper Tennessee River basin in southwestern Virginia, USA. The genetic analysis shows that three out of the seven surveyed populations are genetically distinct, while the other four populations show signs of recent admixture. The populations have low effective population sizes and are subjected to inbreeding, genetic drift, and genetic divergence among populations.

Summary: In this study, the homologue of hnRNPM in triploid fish was cloned and identified. It was found that hnRNPM negatively regulated the RLR signaling pathway and suppressed the IFN signaling mediated by IRF7 in the antiviral innate immune response. It also affected virus replication and enhanced host cell antiviral activity.

Summary: This study successfully produced two triploid individuals through inducing chromosome doubling in female gametes of 'Maya' jujube, with the highest efficiency achieved under specific conditions. The triploid individuals showed significant growth advantages at 18 months old, indicating that inducing 2n megaspores is an effective approach for generating triploid jujube. These results are expected to promote and accelerate triploid breeding in fruit trees.

Summary: The study aimed to confirm and expand earlier findings on genotypic stability and G x E interactions in triploid hybrid clones of P. tomentosa Carr. Results showed significant clonal and site effects, as well as interactions in fiber properties and growth traits. Most triploid hybrid clones had higher reaction norms to improved growth conditions and higher phenotypic plasticity, with accurate estimation requiring more clonal testing sites for growth traits compared to fiber properties.

Summary: Hybrid crops rely more on pollinators compared to open-pollinated crops, and some viable pollen grains can be produced from triploid watermelons, but with a low germination rate, indicating a minimal effect on hybrid watermelon reproduction.

Summary: In this study, primary trisomy was successfully achieved in Populus as a model system for tree and woody perennial plant biology. Numerous abnormalities were observed during meiosis of the triploid hybrid clone, but they did not lead to complete pollen abortion. By developing 19 SSR primer pairs, two trisomies in Populus were detected using SSR markers and somatic chromosome counting. These findings provide a powerful genetic tool for studying gene function in Populus.
