Selection of slash pine elite genotype for tissue culture and fast propagation

Using the sprouts of slash pine as explants,medium formulation for the first generation and multiplication was optimized.The results showed that the optimum medium for the first generation was B5+6-BA 2.0 mg•L-1,and B5+6-BA 2.0 mg•L-1 +IBA 0.1 mg•L-1 for multiplication.The elite genotypes selected for the purposes included 132 from the non-antidisease and 2 from the antidisease families of the slash pine.
