The Connection Between Molecular Indicators and Morphological Traits in Plants and Other Organisms by using A Special Indicator

Abstract

Molecular and morphological indicators were measured to study the relationship, the RAPD marker was used as a molecular indicator, plant height, grain weight, and grain density were used as morphological traits in bread wheat, and 10 primers which have a type (op) were used in RAPD marker, 10 wheat cultivars were used as genotypes for studying. In study calculated, the number of bands which were appeared in every genotype, plant height, grain weight, and grain density as morphological traits, the results were: the C9 treatment gave a higher number of bands, but C6 which gave a higher value in plant height, C7 superior in grain weight and grain density. Mun indicator appeared high relationship between the C7 genotype and the number of fragments or genes in plant height while the C5 genotype gave less relationship, C7 genotype appeared high relationship between the number of fragments and grain weight trait according to Mun indicator while C5 genotype gave a less relationship. In a grain density trait, the C7 genotype gave a high value in Mun indicator comparison with the C5 genotype which gave less relationship, which means that all genotypes had variations in relationship with molecular indicator effects.
