“…Ascorbic acid is required to form and repair tissues throughout the human body. These results are in agreement with the findings of Anuradha and Sood (2019), Thakur et al (2019) and Sood (2022) who also reported significant variation for these traits in their experimental material. Bell pepper with a TSS of 3.3 oBrix or more is typically preferred for producing numerous processed products in processing industries.…”

Hybridization among diverse parents is a great way to create variability within a genus with a narrow genetic base. During Kharif, 2021 and 2022, an experiment was conducted in bell pepper at the research farm of Department of Vegetable Science and Floriculture, CSKHPKV, Palampur (HP) using randomized complete block design under open field conditions to evaluate 15 diverse parents (12 lines and three testers) and their 36 F1 hybrids developed through triple test cross mating design along with two standard checks for eight yield and quality traits. Significant variations were noticed among all the genotypes for all the characters under study. Based on the overall mean performance in pooled environments, cross-combinations viz., HPB-7 × California Wonder, HPB-7 × HPB-39-CW, HPB-2-16 × HPB-39, HPB-6-1 × California Wonder and HPB-29 × HPB-39 were found top highest yielders. Besides the highest yielders, they were reported earliest in flowering and picking, containing more primary branches and a good amount of capsanthin, TSS and ascorbic acid content. Hence, these cross-combinations can be directly released as hybrids after multi-location/farmers’ field testings or can be used in further breeding programmes.

“…Studying the genetic diversity of species is not only helpful to explore its adaptability and evolution history, but also provides an important theoretical basis for the protection and utilization of species [ 31 ]. In this study, 48 pairs of polymorphic primers were screened from 57 pairs of SSR primers designed in the genome of chayote.…”

Background Chayote is a high economic crop in the Cucurbitaceae family, playing an important role in food production, disease treatment and the production of degradable materials in industries. Due to the harsh environment, such as high temperature, drought and frost, some chayote resources are gradually disappearing. It is crucial to collect, characterize, and conserve chayote resources. However, the genetic diversity of chayote resources in China has not been studied so far. Results In this study, we collected 35 individuals of chayote from 14 provinces in China. Subsequently, we found 363,156 SSR motifs from the chayote genome and designed 57 pairs of SSR primers for validation. Out of these, 48 primer pairs successfully amplified bands, with 42 of them showing polymorphism. These 42 primer pairs detected a total of 153 alleles, averaging 3.64 alleles per locus. The polymorphic information content ranged from 0.03 to 0.78, with an average value of 0.41, indicating a high level of polymorphism. Based on the analysis using STRUCTURE, PCoA, and UPGMA methods, the 35 chayote individuals were divided into two major clusters. Through further association analysis, 7 significantly associated SSR markers were identified, including four related to peel color and three related to spine. Conclusions These molecular markers will contribute to the analysis of genetic diversity and genetic breeding improvement of chayote in the future.

The utilization of Trichoderma longibrachiatum filtrate as a safe biocontrol method for producing zinc nanoparticles is a promising approach for managing pests and diseases in agricultural crops. The identification of Trichoderma sp. was achieved through PCR amplification and sequencing of 18s as ON203115, while the synthesis of ZnO-NPs was accomplished by employing Trichoderma filtration. The presence of ZnO-NPs was confirmed by observing a color change to dark green, along with the use of visible and UV spectrophotometers, and the formation and chemical structure of ZnO-NPs were examined. Direct exposure to ZnO-NPs exhibited a significant inhibitory effect on the growth of Fusarium oxysporum at 80.73% compared with control. Also, the percent mortality of Meloidogyne incognita second juveniles stage (J2s) results showed 11.82%, 37.63%, 40.86%, and 89.65% after 6, 12, 24, and 72 h, respectively in vitro. Disease resistance was assessed in the greenhouse against M. incognita and F. oxysporum using the drench application of ZnO-NPs. The application of ZnO-NPs significantly reduced the disease severity of F. oxysporum and improved the quality and quantity of sweet pepper yield. In addition, the application of ZnO-NPs to M. incognita resulted in a significant reduction in the number of nematode galls, egg masses per root, eggs/egg mass, and females by 98%, 99%, 99.9%, and 95.5% respectively.Furthermore, it was observed that the application of ZnO-NPs to pepper plants not only inhibited the growth of F. oxysporum and M. incognita, but also promoted the recovery of pepper plants as indicated by improvements in stem length by 106%, root length 102%, fresh weight 112%, root fresh weight 107%, and leaf area 118% compared to healthy control plants. Additionally, real-time PCR application and DD-PCR technique revealed that the application of ZnO-NPs stimulated the secretion of certain enzymes. These findings suggest that the biosynthesized ZnO-NPs possess anti-nematode and antifungal properties, making them effective for protecting plants against M. incognita and F. oxysporum invasion in soil. This study significantly contributes to our understanding of the nematicidal and fungicidal activities of ZnO-NPs in suppressing soil-borne diseases.
