New superior varieties (VUB) are a reliable technological innovation to increase rice productivity. This study aims to determine the yield potential of some lowland rice VUB. The assessment was carried out on land owned by a member of the Sumber Rejeki Farmer Group, Cintaratu Village, Lakbok District, Ciamis Regency at Dry Season II in June-September 2020. The study used a randomized complete block design (RCBD) with six varieties of treatment and was repeated ten times. The varieties tested were Inpari 32, Inpari 42, Padjadjaran, Cakrabuana, Inpari IR Nutrizinc, and Siliwangi varieties. The variables observed included the growth component, yield component, and yield component. Data were analyzed using the F test followedby the Duncan Multiple Range Test at the Q=5% level. In addition, a correlation test was conducted between the growth components, yield components, and yields. The results of the study indicated that the new superior rice varieties studied had different performance in growth, number of tillers, yield, and yield components. Inpari 42 variety produced the highest productivity, namely 6.88 ton ha-1 which was supported by the number of grains per panicle, percentage of filled grains per panicle, and percentage of empty grain per panicle which were better than other varieties. Plant height and number of grains per panicle were positively correlated with yield.

Fungal endophytes are microorganisms living symbiotically with a host plant. They can produce volatile organic compounds (VOCs) that have antimicrobial activity. This study aimed to isolate endophytic fungi from Barleria prionitis plants grown in Thailand and to investigate the antifungal properties of their VOCs against Colletotrichum acutatum, a causal agent of anthracnose disease on post-harvest strawberry fruits. A total of 34 endophytic fungi were isolated from leaves of B. prionitis. The VOCs produced from each individual isolate were screened for their antifungal activity against C. acutatum using a dual-culture plate method. From this in vitro screening experiment, the VOCs produced by the endophytic isolate BP11 were found to have the highest inhibition percentage (80.3%) against the mycelial growth of C. acutatum. The endophytic isolate BP11 was molecularly identified as Daldinia eschscholtzii MFLUCC 19-0493. This strain was then selected for an in vivo experiment. Results from the in vivo experiment indicated that the VOCs produced by D. eschscholtzii MFLUCC 19-0493 were able to inhibit infections by C. acutatum on organic fresh strawberry fruits with an average inhibition percentage of 72.4%. The quality of the pathogen-inoculated strawberry fruits treated with VOCs produced by D. eschscholtzii MFLUCC 19-0493 was evaluated. Their fruit firmness, total soluble solids, and pH were found to be similar to the untreated strawberry fruits. Solid phase microextraction-gas chromatographic-mass spectrometric analysis of the VOCs produced by D. eschscholtzii MFLUCC 19-0493 led to the detection and identification of 60 compounds. The major compounds were elemicin (23.8%), benzaldehyde dimethyl acetal (8.5%), ethyl sorbate (6.8%), methyl geranate (6.5%), trans-sabinene hydrate (5.4%), and 3,5-dimethyl-4-heptanone (5.1%). Each major compound was tested for its antifungal activity against C. acutatum using the in vitro assay. While all these selected VOCs showed varying degrees of antifungal activity, elemicin was found to possess the strongest antifungal activity. This work suggests that D. eschscholtzii MFLUCC 19-0493 could be a promising natural preservative for controlling C. acutatum associated anthracnose disease in strawberry fruits during the post-harvest period.

Abstract. Sayekti TWDA, Syukur M, Hidayat SH, Maharijaya A. 2021. Diversity and genetic parameter of chili pepper (Capsicum annuum) based on yield component in three locations. Biodiversitas 22: 823-829. With the increase in the use of chili, it is necessary to develop these commodities through plant breeding activities. Phenotypes are not only determined by genetics, but also by environmental factors and the GxE interactions, so all the factors need to be considered. The aims of this study were to evaluate the variability of ten elite breeding lines and three commercial varieties of chili pepper (Capsicum annuum L.) across three different environments. This experiment was conducted in three environments namely Bogor, Kolaka, and Palembang, from January until July 2019. Thirteen genotypes consisting of ten elite lines and three commercial chili pepper were used. This experiment was arranged in a randomized complete block design (RCBD) with three replications for each environment. To determine the effect of environment, Combined Analysis of Variance was carried out for all environments using PBSTAT-GE. The environment used in this experiment was lowland that varies between each other. The genotype with the fastest harvesting age relative in three environments was F7-145293-19-8-3-113-1. The highest number of fruits per plant was observed in genotype F9-160291-9-4-3-2-1-1-1 with 261 fruits per plant. The highest yield was observed in genotype F7-145174-9-7-1-5-3. From the clustering analysis, this population was grouped into five clusters. The heritability values for the 12 observed traits ranged between 22.68-69.97%, classified into high and moderate criteria.

How is personal pride, the backlash against political correctness, and the desire to be “better” than those around you, helpful or harmful to society? In this work of philosophical short story fiction, the narrator lives in a divided society. She lives in the American Political Union, a community that has worked hard to stamp out all comparisons between its members so that no one will feel bad about their relative attractiveness, or intelligence. In fact, people are required to move about the city in mobile crates, thus hiding their appearance. Furthermore, it is deemed culturally taboo to brag or express higher value in intellectual accomplishments. The main character, an intelligent student, convinces her friend to jump the border into the Old American Republic, a community where people are judged, sorted, compared, and it is almost impossible to interact with those of higher orders than yourself. The girls escape to the Old American Republic only to find that judging takes many different forms, and that happiness for those that view themselves as superior is not as easily found as is always expected. This story, like all After Dinner Conversation stories, has suggested discussion questions at the end.

Aims: To identify the causal agent of anthracnose disease of Solanum torvum, determine whether the pathogen is seedborne and also to ascertain the cross infection potential of the pathogen on other Solanaceous crops of economic importance. Place and Duration of Study:  Bunso, in the East Akim District of the Eastern Region of Ghana, between January and October, 2017. Methodology: The disease symptoms on matured fruits, leaves, stems and flowers of Solanum torvum were carefully observed for documentation with magnifying glasses and the naked eyes. The pathogen was isolated on PDA after incubation for five days and the identification was based on the colony, morphology and conidial characteristics with reference to laboratory manuals. The virulence of the fungal isolates from the S. torvum fruits was determined through pathogenicity tests. A seed health test was conducted in accordance with the International Seed Testing Association (ISTA) to determine whether the pathogen is seedborne. Conidial suspension of Colletotrichum acutatum (1×103 per ml) was used to inoculate pepper and eggplant fruits in a cross infectivity test. Results: Colletotrichum acutatum was repeatedly isolated and identified as the causal agent of the disease on the fruits and was also seedborne. In cross infectivity studies, the pathogen produced characteristic anthracnose symptoms on both eggplant and pepper which happens to belong to the same Solanaceae family just as the turkey berry. Conclusion: The anthracnose disease of Solanum torvum at Bunso, in the Eastern Region of Ghana is caused by Colletotrichum acutatum that has the potential to cross infect other Solanaceous species. This study is the first scientific report of the occurrence of anthracnose disease of S. torvum in Ghana.

In the paper, an application of the methodology for analyzing yield as affected by its components that develop at the same ontogenetic level is discussed; it may also be applied to any model in which several traits developing non-sequentially affect their product. The methodology is called “nonsequential yield component analysis”. Two applications are presented; the proposed approach is compared with path analysis, commonly applied for yield component analysis, and Piepho’s approach. In one example, grain yield of two cultivars of winter triticale (×<i>Triticosecale</i> Wittmack), Fidelio and Bogo, as affected by harvest index and biomass yield, was studied; the results of the three approaches compared were similar. However, in the study of nitrogen uptake as affected by nitrogen-uptake efficiency and crop nitrogen supply (the problem for which yield component analysis may be applied because of the underlying multiplicative model), the results of the methods were different. For both cultivars, path analysis and Piepho’s method showed a much stronger influence of crop nitrogen supply on nitrogen uptake than that of nitrogen-uptake efficiency. In the proposed method, however, both these component traits influenced nitrogen uptake to a similar extent. The proposed method is shown to be methodologically better than the other approaches, and to provide different results in some situations. Hence, the new method should be used for nonsequential yield component analysis although it is suggested that path analysis may be applied if the determination coefficient of the linear model is close to 100%.
