Diallel analysis is a methodology used in the genetic improvement of plants. One of its main purposes is to provide subsidies for early identification of promising crosses for the development of high yielding inbred lines. Several articles have been published in diallel analysis, and many recommendations were made either for the selection of certain crosses of lines for hybrids or for the development of competitive inbred lines. However, articles about the validation of information predicted by these analyses and the results in the field are scarce or nonexistent. The objective of this article was to validate diallel analysis using model IV of Gardner and Eberhart published in 1966, a methodology recommended to identify promising crosses among developed inbred lines in red rice. We compared the recommendations of the diallel analysis crosses with the process end the result of inbreeding generations. Recommended crosses by the diallel analysis were different from those obtained after generations of self-fertilization and selection. However, two of the four selected parents were matched. Considerations were made about the accuracy of diallel analysis and the need to validate in practice methodologies that theoretically are of great value.

Abstract This study reports the first assessment of endophytic fungi isolated from strawberry leaves and selection of isolates for the control of Duponchelia fovealis, a new pest of strawberries. A total of 400 strawberry leaves of the cultivar ‘Albion’ were collected in four commercial farms. Leaves were disinfected, cut in fragments, and placed on Petri dishes containing potato dextrose agar media with tetracycline and incubated for 30 days. Following this time, 517 fungal colonies were isolated, and thirteen genera were identified: Cladosporium, Aspergillus, Nigrospora, Fusarium, Trichoderma, Chaetomium, Alternaria, Paecilomyces, Penicillium, Ulocladium, Bipolaris, Diaporthe, and Phoma. Eight isolates belonging to the genera Aspergillus, Diaporthe, Paecilomyces, and Cladosporium were selected for pathogenicity bioassays against third instar larvae of D. fovealis. Isolates of Paecilomyces induced the highest mortality rates.

Dryland area in Indonesia reaches 108.8 millions ha (69.4%) of the total dry land with the potential to expand the area of food crops reaching 7.1 million ha, which is dominated by ultisol and oxisol soil types. Plant constraint cultivation on ultisol soil types is the acidic soil pH with high Al and Fe levels. One of the efforts that can be made to cultivate plants on ultisol soil is the selection of plants that are tolerant of Fe stress. This study aimed to determine a tolerance level and F6 red rice lines that were tolerant of iron (Fe) stress in ultisol soils. The experimental design used was factorial Completely Randomized Design (CRD) consisting of 2 factors, the first factor consisted of 12 treatments (10 test lines and 2 comparison varieties) and the second factor  was iron stress with concentrations (0 ppm and 551,55 ppm). The stress was applied after 3 WAP. The stress resistance test to iron (Fe) should that all lines of red rice F6 on ultisol soils have a score of 1 which indicates the stress tolerance of Fe at a concentration of 551,55 ppm Fe. The 23A-56-30-25-12 and 23A-56-30-25-13 lines were the best lines that were tolerant of 551,55 ppm iron (Fe) stress with the highest growth and yield. The lines tested can be developed on ultisol soils because they are tolerant of Fe.

Abstract Upland rice with a high yield becomes a priority in rice breeding activities. High yield can be obtained if the rice plant has lodging resistance. This study aims to determine the yield and selection of F7 upland rice lines as the candidate for superior varieties with lodging resistance. The research was conducted in ultisol land, Bangka Regency, Bangka Belitung Islands Province. The study used the experiment method with randomized block design (RBD) with three replications. The treatment used F7 upland rice lines and 5 genotypes as check varieties. The five of F7 lines used were 19I-06-09-23-03, 21B-57-21-21-23, 23F-04-10-18-18, 23A-56-20-07-20 and 23A-56-22-20-05. The five check viarieties used were Danau Gaung, Inpago 8, Inpago 12, Rindang and Situ Patenggang. Data was analyzed using ANOVA and Least Significant Increase (LSI) test. The results showed that 2 lines had a higher yield than the comparison genotypes were 23A-56-22-20- 05 and 23F-04-10-18-18. Hence, the recommended lines as the candidates for superior varieties with lodging resistance are 23A-56-22-20-05 for red rice type and 23F-04-10-18-18 for white rice type.

Ralstonia solanacearum has been known to cause bacterial wilt disease on chili pepper.  Despite many reports on the potential use of endophytic fungi to induce plant resistance, its utilization to suppress bacterial wilt disease of chili has not been widely reported.  The aims of this research was to screen potential endophytic fungi that may increase chili resistance against bacterial wilt disease.  Selection of endophytic fungi was done using in vivo and antibiosis test. Strains of fungi were considered the most potent in suppressing the development of bacterial wilt in chilli were identified. Ten out of 62 isolates of endophytic fungi gave the highest suppression on chilli’s bacterial wilt disease.  Most strains of endophytic fungi were able to suppress the development of bacterial wilt disease, but not always positively correlated to the vegetative and generative growth of chilli. Based on the level of disease intensity and the growth of plants were obtained three strains of endophytic fungi that considered potentially suppress the incidence of bacterial wilt disease.  The three isolates was identified as Fusarium solani f.sp. phaseoli (AC-2.13 and AC-4.4) and Trichoderma asperellum (AC-3.18) using morphology and molecular characters. Although all three selected isolates were able to suppress bacterial wilt disease in this study, but application of F. solani f.sp. phaseoli should be considered in practical use since it is generally known as the causal agent of root rot disease of beans

Endophytic fungi (EF) are increasingly gaining attention due to the numerous benefits many species can offer to the plant host, while reducing the application of chemicals in agriculture, thus providing advantages to human health and the environment. The growing demand for safer agrifood products and the challenge of increasing food production with a lower use of pesticides and fertilizers stimulates investigations on the use and understanding of EF. Other than direct consequences on the plant damaging agents, these microorganisms can also deliver bioactive metabolites with antimicrobial, insecticidal, or plant biostimulant activities. In tomato, EF are artificially introduced as biological control agents or naturally acquired from the surrounding environment. To date, the applications of EF to tomato has been generally limited to a restricted group of beneficial fungi. In this work, considerations are made to the effects and methods of introduction and detection of EF on tomato plants, consolidating in a review the main findings that regard pest and pathogen control, and improvement of plant performance. Moreover, a survey was undertaken of the naturally occurring constitutive endophytes present in this horticultural crop, with the aim to evaluate the potential role in the selection of new beneficial EF useful for tomato crop improvement.
