Morphological and molecular characterization of onion (Allium cepa L.) genotypes using RAPD markers

The present study carried out to with a view characterize and validate the RAPD marker’s genetic diversity at morphological molecular levels in thirty cultivars of onion (Allium cepa L.). This work aimed determine their important traits, DNA polymorphism decipher variation. agro-morphological characters such as germination percentage, plant height, leaf colour, waxiness, foliage attitude, bulk colure shape genotypes were studied. assessed using four markers (OPB-09, OPA-16, OPB-16, OPA-09). It revealed significant genotypic differences genotypes. Significant was observed by UPGMA analysis. analysis yielded 98.21% average (genetic diversity) 901 amplicons. OPA-9 showed 100% only OPB-9 produced 92.85% polymorphism. primers discriminated into two major clusters method UPGMA. cluster (cluster-A) contains 28 another minor (cluster-B) which (1403 1432/33). exhibited statistically variability, gives an opportunity use them for varietal development through breeding programs. key findings current would be insight strategies cultivars.
