Abstract

The current research was conducted to investigate segregation of pulp pigments and seed related parameters in the full-sib progenies derived from ‘Allahabad Safeda’ (♀) and ‘Arka Kiran’ (♂) cross. Fifty, four-year-old fullsib progenies confirmed through SSR markers along with their parental genotypes were evaluated. Significant variability was observed for seed related parameters including seed length, width, and seed weight per fruit, seed hardness as well as for pigments like lycopene and β-carotene contents, indicated wide genetic diversity and segregation. Pulp colour revealed predominance of Red group pulp colour progenies (45 Nos) over White group (5 Nos). Lycopene content ranges from 0.31 to 23.21 mg/100 g and β-carotene from 0.08 to 1.95 mg/100 g, with several progenies surpassing values in both the parents, indicating transgressive segregation and strong potential for nutritional improvement. Correlation analysis revealed significant positive association among seed parameters, particularly between seed weight per fruit and seed number, while seed parameters showed no significant correlation with lycopene and β-carotene contents, suggesting their independent inheritance. Principal component analysis indicated that first four components (PC 1-4) accounted for 81.88% of the total genetic variation, with carotenoids loading independently from seed morphology. Hierarchical clustering grouped the full-sibs into five distinct clusters, reflecting substantial genetic divergence for selecting superior genotypes with desirable traits.
