Impact of carbohydrate metabolism pathways on bearing habit of mango (Mangifera indica L.) genotypes

Heterozygosity is the major constraint in perennial fruit crop like mango for regular bearing breeding. Majority of popular varieties have irregular habit. Many external and internal factors affect habit crops. Among factors, level carbohydrate reserves phytohormones plays a role on crops apple, citrus, mango, litchi etc., Therefore, present research work aimed to study metabolism pathways genotypes varying origin. A total 30 primers were designed using silico mining four key genes coding citrate synthase, alcohol dehydrogenase, sucrose phosphate synthase trehalose synthase. These play important sugar starch mango. Of these specific primers, 14 showed polymorphism among studied. Gene diversity (GD), average number alleles per locus (An), information content (PIC) allele frequency (Maf) observed 0.45, 2.14, 0.35, 0.59, respectively. Simple sequence repeats markers grouped 63.15% studied bearers together. Further, could be utilized greater regularity.
