Scion/Rootstock Interaction Studies for Quality Traits in Mango (Mangifera indica L.) Varieties

To explore the quality rootstocks which impart better fruits in mango varieties, we studied interactive effect of scion and rootstock using five varieties (Mallika, Amrapali, Dashehari, Pusa Arunima, Surya) grafted on three (Olour, Kurukkan, K-5). A total 25 physico-chemical parameters were viz., fruit weight, yield efficiency, per plant, pulp percent, soluble solids (TSS), acidity, physiological loss weight (PLW), peel thickness, respiration rate, etc., found to be altered through scion–rootstock interaction. Among Olour proved best improve shelf life grafting approach. Physico-chemical-traits-based clustering was unable precisely group according their rootstock. 35 shelf-life specific markers designed from ripening genes, such as expansin, polygalactouranase, ethylene insensitive, sensitive, etc. Of these primers, 24 showed polymorphism among genotypes. The gene diversity (GD), allele locus (An), information content (PIC), major frequency (MAF) observed 0.43, 2.00, 0.34, 0.63, respectively. Cluster analysis clearly that Kurukkan rootstock, K-5 grouped together have more similarity. eight simple sequence repeats loci (SSRs) associated with traits.
