13 extractive question-and-answer pairs built from Assessment on therapeutic value and diversity analysis in traditional rice (Oryza sativa) landraces of Tamil Nadu | The Indian Journal of Agricultural Sciences, published by epubs.icar.org.in. Source-evidenced topics include therapeutic value, diversity analysis, traditional rice, oryza sativa, tamil nadu, pigmented rice, biochemical profiling, therapeutic trait improvement. 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: 7 factual, 2 list, 2 relationship, 2 summary. 6 of the 13 pairs (46.2%) ask explanatory questions; the remaining 7 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset contains 13 extractive question-and-answer pairs derived from a study on the therapeutic value and diversity analysis of traditional rice landraces in Tamil Nadu. The research focuses on pigmented rice varieties, their biochemical profiling, and their potential for therapeutic trait improvement. It also includes diversity analysis, grouping landraces into clusters based on genetic traits. The dataset provides detailed insights into specific rice genotypes, their bioactive compound content, and antioxidant activity, alongside metadata about the journal publishing the study.
