10 extractive question-and-answer pairs built from Association of Colletotrichum species with anthracnose of tropical fruit crops in Southern Karnataka and Andhra Pradesh, India | The Indian Journal of Agricultural Sciences, published by epubs.icar.org.in. Source-evidenced topics include colletotrichum species, anthracnose, tropical fruit crops, southern karnataka, andhra pradesh, india, c. gloeosporioides, c. truncatum. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. Question types in the export: 6 factual, 3 definition, 1 summary. 4 of the 10 pairs (40.0%) ask explanatory questions; the remaining 6 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset contains 10 extractive question-and-answer pairs focused on the association of Colletotrichum species with anthracnose disease in tropical fruit crops in Southern Karnataka and Andhra Pradesh, India. The study explores the diversity of Colletotrichum spp. for sustainable disease management and plant biosecurity, with samples collected during the rabi and kharif seasons of 2020 and 2021. Key findings include the identification of species complexes, characteristic symptoms of anthracnose, and growth rates of specific isolates.

| What are the characteristic symptoms of anthracnose disease? | dark, sunken lesions with visible acervular aggregates at advanced stages of infection. | Severe pre- and post-harvest losses occur in tropical fruit crops by fruit rot pathogens especially Colletotrichum spp., causing anthracnose disease. The wide host range of the pathogen is associated with the prevalence of different species in the fruit orchards. for the study, samples were collected during the winter (rabi) season of 2020 and the rainy (kharif) season of 2021 from Southern Karnataka and Andhra Pradesh to explore the diversity of Colletotrichum spp. for sustainable disease management and plant biosecurity. Characteristic symptoms of anthracnose included dark, sunken lesions with visible acervular aggregates at advanced stages of infection.

| What type of conidia and colonies does C. gloeosporioides produce? | cylindrical conidia and white aerial mycelial colonies | Eight isolates were assigned to the C. gloeosporioides species complex, producing cylindrical conidia and white aerial mycelial colonies, while one isolate (IIHR_COL_C8) was identified as C. truncatum, producing falcate conidia and dark grey colonies with concentric zonation. Multigene phylogenetic analysis using partial sequences of ITS, ACT, GD, SOD2 and TUB2 in MEGA X further resolved the isolates into three species: C. siamense (n=7), C. musae (n=1), and C. truncatum (n=1). The mean conidial size of C. siamense ranged from 10.16–14.18 μm × 3.76–5.34 μm, C. musae measured 12.01 μm × 3.83 μm, and C. truncatum is 21.45 μm × 2.57 μm. The mean growth rate of C. siamense ranged from 10.56–12.92 mm/day, C. musae was 12.61 mm/day, and C. truncatum was 7.47 mm/day.
