Effect of Certain Mutagenic Agents on Salt Tolerance Behavior of Some Citrus Rootstocks-B. Selection and Identification of Mutations
Identification of citrus rootstocks mutations was done according to morphological features Leaf area, leaf width (W) , leaf length (L) , W/L ratio, and injury score, and RAPD analysis. UPGMA program was used to construct a similarity matrix (UPGMA dendrogram) for three citrus rootstocks (sour orange, Cleopatra mandarin and Troyer citrange) and their expected mutant seedlings. Simple matching coefficient ranging from (0.07 to 1)suggested a broad morphological base for citrus genotypes. According to morphological analysis, it was found that control seedlings of studied citrus rootstocks and mutant seedlings differed in their behavior under salinity condition. Furthermore, results of RAPD marker indicated that the selected mutant seedlings varied in their genetic structure as compared with control seedlings, though, these seedlings could be considered as salt tolerant mutants. The combination of the morphological and RAPD data was in accordance with RAPD data. Further studies will be made to emphasize of stability of such mutants and to determine the effect of such mutants on vegetative growth and fruit quality of scions.
