“…In Capsicum genus, resistance control depends on the plant organ under study, such as leaf or fruit (Mahasuk et al, 2009a). In the case of fruit, resistance may also vary with maturation stage, whether immature or mature (Silva et al, 2014;Sun et al, 2015;Suwor et al, 2015). In this study, we noticed that immature fruit was more susceptible to anthracnose than mature ones, which corroborates the hypothesis of different genetic control in these maturation stages.…”

ABSTRACT. This study aimed to identify Capsicum genotypes with resistance to bacterial spot (BS), anthracnose and Pepper yellow mosaic virus (PepYMV). Fifty-four genotypes of Capsicum spp were evaluated. Resistance reaction against BS was evaluated using three replicates, testing hypersensitivity and quantitative resistance in leaves. After evaluation, inoculated leaves were detached from the plants, being then cultivated until reproductive stage for evaluations anthracnose resistance in immature and mature fruit, totalizing 18 fruits per genotype. For PepYMV resistance was performed with five replications. Each genotype reaction was evaluated by a scoring scale, using the area under the disease progress curve for each pathosystem, and incubation period for the three systems. The latent period was evaluated only for the pathosystem Capsicum-Colletotrichum gloeosporioides. Means were grouped by the Scott-Knott test. Measures of dissimilarity matrix among the genotypes were obtained by Gower's algorithm and the grouping was obtained by the UPGMA clustering method. The accessions belonging to the Capsicum frutescens were the most susceptible to the three diseases. At least one genotype of Capsicum baccatum var. pendulum, Capsicum annuum, and Capsicum chinense showed resistance potential to BS and PepYMV, for use in breeding programs. The accession UENF 1381 (C. annuum) was resistant to the three pathogens.

Pepper (Capsicum spp.) is one of the major vegetable crops grown worldwide largely appreciated for its economic importance and nutritional value. This crop belongs to the large Solanaceae family, which, among more than 90 genera and 2500 species of flowering plants, includes commercially important vegetables such as tomato and eggplant. The genus includes over 30 species, five of which (C. annuum, C. frutescens, C. chinense, C. baccatum, and C. pubescens) are domesticated and mainly grown for consumption as food and for non-food purposes (e.g., cosmetics). The main challenges for vegetable crop improvement are linked to the sustainable development of agriculture, food security, the growing consumers’ demand for food. Furthermore, demographic trends and changes to climate require more efficient use of plant genetic resources in breeding programs. Increases in pepper consumption have been observed in the past 20 years, and for maintaining this trend, the development of new resistant and high yielding varieties is demanded. The range of pathogens afflicting peppers is very broad and includes fungi, viruses, bacteria, and insects. In this context, the large number of accessions of domesticated and wild species stored in the world seed banks represents a valuable resource for breeding in order to transfer traits related to resistance mechanisms to various biotic stresses. In the present review, we report comprehensive information on sources of resistance to a broad range of pathogens in pepper, revisiting the classical genetic studies and showing the contribution of genomics for the understanding of the molecular basis of resistance.

“…Selanjutnya, massa konidia dihomogenkan dan disaring dengan menggunakan kain moslen. Kepadatan inokulum minimal yang digunakan, yakni sebanyak 10 5 konidia/mL hingga diperoleh larutan suspensi konidia sebanyak 9 L. Kepadatan suspensi, yakni 10 5 konidia/mL merupakan kepadatan yang dianjurkan dalam inokulasi buatan patogen cendawan Colletotrichum capsici (Suwor et al 2015). Selanjutnya, 9 L suspensi cendawan Colletotrichum capsici tersebut diaplikasikan dengan cara disemprotkan (masing-masing 100 mL) pada saat tanaman memasuki fase generatif di bagian buah dan daun tanaman cabai uji (9 tanaman per perlakuan dengan 3 ulangan).…”

Penyakit tanaman yang sering ditemukan menyerang cabai pada masa prapanen maupun pascapanen adalah penyakit busuk buah atau yang lebih dikenal dengan antraknosa. Antraknosa pada buah cabai disebabkan oleh cendawan Colletotrichum capsici. Saat ini, dalam pengendalian antraknosa diperlukan biofungisida yang efektif, aman, dan ramah terhadap lingkungan serta manusia. Oleh karena itu, dikembangkan biofungisida berbasis kitosan. Kitosan telah banyak dilaporkan peranannya sebagai antimikrob (virus, bakteri, dan jamur) penyebab penyakit pada tanaman. Pengembangan lebih lanjut kitosan dalam rangka meningkatkan aktivitas antimikrob dilakukan dengan sintesis nanokitosan-Ag/Cu. Berdasarkan pengujian diketahui bahwa pada skala laboratorium, Ag-ChNPs 500 ppm dan Cu-ChNPs 1000 ppm mampu menghambat pertumbuhan cendawan Colletotrichum capsici sebesar 17,3 dan 42,3%, sedangkan pada skala rumah kaca perlakuan Ag-ChNPs 500 ppm dan Cu-ChNPs 1000 ppm berpotensi secara signifikan menghambat perkembangan Colletotrichum capsici yang ditunjukkan dengan penekanan kejadian penyakit pada tanaman cabai varietas Tanjung, Ciko, dan Kencana. Secara mikroskopis aktivitas senyawa antimikrob pada keduanya menyebabkan kerusakan pada hifa cendawan yang ditandai dengan malformasi yang menyebabkan hambatan pada pertumbuhan hifa. Pada cawan petri ditunjukkan dengan timbulnya zona hambat berupa wilayah bening di sekitar kertas cakram yang diberi perlakuan.
