Description F1 progenies resulting from a 10 x 10 diallel cross including
reciprocals, in peanut (Arachis hypogaea L. ) cultivars of different
susceptibility to the jassid, Empoasca kerri Pruthi, were studied
to determine the inheritance of trichomes on the adaxial surface
of the leaf, leaf midrib, and petiole, and their association with
resistance to E. kerri. Genotypes or crosses with long trichomes
on the leaves and petioles showed a high level of resistance to
jassids (leafhoppers) as evidenced by a very low percentage of
yellowed foliage (hopper bum). Nonadditive genetic variance
was predominantly observed for all trichome characters. However,
additive genetic variance was also important for the presence
of long trichomes on the midrib and petioles and for jassid
damage. NC Ac 2230, a jassid resistant line, is the best parent
to use in a breeding program because of its stable resistance
and high general combining ability for the presence of trichomes.
