4 extractive question-and-answer pairs built from Analysis of genetic diversity using D2 in Indian Mustard [Brassica juncea (L.) Czern & Coss.] genotypes for morphophysiological characters under heat stress condition | Annals of Agricultural Research, published by epubs.icar.org.in. Source-evidenced topics include genetic diversity, d2 analysis, indian mustard, brassica juncea, morphophysiological characters, heat stress, mahalanobis’s d2 statistical method, genotypes. 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: 2 comparison, 1 definition, 1 factual. 3 of the 4 pairs (75.0%) ask explanatory questions; the remaining 1 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset contains extractive question-and-answer pairs derived from a study on genetic diversity in Indian mustard (Brassica juncea) using Mahalanobis’s D2 statistical method. The research evaluated 18 genotypes under heat stress conditions during the rabi season of 2020-21. The D2 analysis grouped the genotypes into six clusters, with Cluster I containing the highest number of genotypes. Key metrics such as intra-cluster and inter-cluster distances were calculated to assess genetic diversity and clustering patterns.

| What statistical method was used to assess genetic diversity in Indian mustard? | Mahalanobis’s D2 statistical method | This study aimed to assess genetic diversity in Indian mustard [Brassica juncea (L.) Czern & Coss.] using Mahalanobis’s D2 statistical method. Eighteen genotypes, including a check, were evaluated in a Completely Randomized Block Design (CRBD) with three replications at the ICAR-Directorate of Rapeseed-Mustard Research during the rabi season 2020-21. The D2 analysis grouped these genotypes into six clusters. Cluster I had the highest number of genotypes (10), followed by Cluster V (3 genotypes) and Cluster II (2 genotypes), while Clusters III, IV and VI each had a single genotype. The greatest intra-cluster distance was 520.61 for Cluster V. The highest inter-cluster distance was observed between Cluster II and Cluster VI (3770.41), followed by Cluster II and Cluster III (2431.65), with the smallest inter-cluster distance between Cluster III and Cluster VI (587.93). | 106 | definition | 0.940 | https://epubs.icar.org.in/index.php/AAR/article/view/162906 | This study aimed to assess genetic diversity in Indian mustard [Brassica juncea (L.)
