7 extractive question-and-answer pairs built from Assessment of correlation and path analysis for morphophysiological characters in Indian mustard genotypes under heat stress condition | Annals of Agricultural Research, published by epubs.icar.org.in. Source-evidenced topics include indian mustard genotypes, heat stress condition, secondary branches per plant, main shoot length (cm), seeds per siliqua, membrane stability index (%), excised leaf water loss (%), genotypic correlation coefficients. 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: 3 factual, 2 list, 1 comparison, 1 summary. 4 of the 7 pairs (57.1%) ask explanatory questions; the remaining 3 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset examines the correlation and path analysis of morphophysiological traits in Indian mustard genotypes under heat stress conditions. The study, conducted during the rabi season of 2020-21 at the ICAR-Directorate of Rapeseed-Mustard Research, analyzed 21 traits across 18 genotypes using a Complete Randomized Block Design with three replications. Key findings include the identification of traits with positive and negative correlations to seed yield, as well as differences between genotypic and phenotypic correlation coefficients.

| What do the results indicate about the role of morphological and physiological traits in determining yield potential? | both morphological and physiological characteristics significantly impact the yield potential of a genotype | Path coefficient analysis revealed that traits such as siliqua on main shoot length, relative water content (%), plant height (cm), chlorophyll b (mg/g FW), excised leaf water loss (%) and total chlorophyll (mg/g FW) have direct positive effects on seed yield per plant (g). primary branches per plant, main shoot length (cm), water retention capacity of leaves (%) and days to maturity have direct negative effects on seed yield. These findings suggest that both morphological and physiological characteristics significantly impact the yield potential of a genotype, making these traits useful for genotype selection. | 459 | summary | 0.970 | https://epubs.icar.org.in/index.php/AAR/article/view/166200 | These findings suggest that both morphological and physiological characteristics significantly impact the yield potential of a genotype, making these traits useful for genotype selection. | p[0] | 0.700 | valid | |
| How do genotypic correlation coefficients compare to phenotypic correlation coefficients? | genotypic correlation coefficients are slightly higher than phenotypic correlation coefficients | An experiment was conducted with 18 genotypes of Indian mustard (Brassica juncea L. Czern& Coss) in a Complete Randomized Block Design (CRBD) with 3 replications at the ICAR-Directorate of Rapeseed-Mustard Research during the rabi season of 2020-21. The purpose of the study was to assessment the correlation and path analysis for 21 distinct characteristics. The results show that certain traits are positively correlated with seed yield, including the number of secondary branches per plant, main shoot length (cm), siliqua on the main shoot, siliqua per plantand seeds per siliqua. there are significant negative correlations with membrane stability index (%), excised leaf water loss (%) and water retention capacity of leaves (%). Generally, genotypic correlation coefficients are slightly higher than phenotypic correlation coefficients. | 747 | comparison | 0.920 | https://epubs.icar.org.in/index.php/AAR/article/view/166200 | Generally, genotypic correlation coefficients are slightly higher than phenotypic correlation coefficients. | p[0] | |||
