摘要

Although coloured mango varieties hold strong nutritional and commercial value, integrated assessments of their morphological, biochemical, and genetic traits remain limited, especially under Bihar’s agro-climatic conditions. This study hypothesized that these varieties exhibit significant variability and that some genotypes possess superior industrially important traits such as higher antioxidants, better yield components, and improved pulp recovery useful for breeding and processing applications. Fifteen coloured mango varieties were evaluated during 2020–2021 using morphological and biochemical traits, complemented with multivariate and genetic analyses to quantify variability and industrial potential. Superior yields were recorded in Pusa Shrestha, Pusa Pratibha, and Ambika. Higher total soluble solids (TSS), antioxidant activity, and flavonoid content were observed in Pusa Shrestha, Pusa Pratibha, Maya, Arunika, and Kensington, indicating their suitability for nutraceutical use and natural pigment extraction. High genotypic and phenotypic coefficients of variation (49.61% and 51.00%, respectively) and broad-sense heritability (up to 97.90% for fruit length) indicated strong genetic control of key traits. The highest genetic advance as percent of the mean was recorded for pulp weight (99.01%). Correlation analysis revealed significant positive associations among fruit length, breadth, stone weight and pulp recovery. Additionally, Yield also showed a positive association with fruit retention at maturity. Principal Component Analysis explained 89.62% of the total variation through the first seven components, while cluster analysis grouped genotypes into two major clusters and four subclusters. The identified gene pools represent valuable resources for breeding programs and industrial applications, including fruit processing, pigment extraction, and functional food development.
