Commercialization of hybrid cultivars in
jatropha can be considered based on the significant
heterosis for yield and other major agronomic
characters. Although the hybrid vigor in seed yield
was high, hybrid seed production in jatropha was
still achieved by hand pollination and thus would
not be commercially feasible. Genetic/cytoplasmic
male sterility should be identified and incorporated
into the female parent for commercial hybrid
production of jatropha seeds. Although jatropha
grown from seeds has many advantages with
regard to root systems and planting flexibility over
those grown from seedlings, stem cutting
propagation or tissue culture of the best F1 hybrid
can be initially employed to produce hybrid plants,
while male sterility characters are yet to be found.
