GENETIC DIVERSITY ANALYSIS IN SNAPDRAGON (ANTIRRHINUM MAJUS L.) USING MORPHOLOGICAL AND MOLECULAR METHODS
Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 12
Abstract
Snapdragon (Antirrhinum majus L) is an important cut flower and cover plant grown worldwide because of their attractive flowers and long flowering duration. In this context, morphological and molecular characterization was carried out among 20 different accessions (17 local genotypes and 3 commercial cultivars) sampled from Kayseri region, where it is naturally found. The genotypes were evaluated for 15 different morphological characteristics such as leaf blade, flower, plant and time of flowering. Despite the commercial type has higher value (40 mm) than local genotypes for flower length, some local genotypes in terms have wider (11 mm) flower than commercial cultivar. Some local genotypes had higher plant heights than the commercial variety. The minimum value of the leaf length was measured at the number 19 (28 mm), while the maximum value was found at the number 4 (77 mm) in local genotypes. Inter-simple sequence repeat marker analysis (ISSR) indicated that the similarity coefficients were between 0.55 and 0.95. The cluster analysis divided the samples into two main branches. All local genotypes were clustered together in the first subgroup, while the second subgroup included the commercial variety alone. In conclusion, the local snapdragon genotypes were significantly different from the popular commercial cultivar, meaning that they can be used for broadening genetic background of the commercial varieties.
