Reactions of five cowpea breeding lines to field infestation of roots- Knot nematode (Meloidogyne spp.)
ABSTRACT
Reactions of
five cowpea breeding lines (IT 90K-76, TVX —3236, IT97K-400-3, IT86D-17 and
IT82F-16) to Root—knot nematode (Meloidogyne spp) was investigated in a
naturally infested field. Plants were randomly sampled from each breeding line
and observed for nodule, root galls, seed weight, fresh and dry shoot weight,
Fresh and dry root weight, flowering days and percentage germination. The
nematode population before planting and at harvest was also recorded. Data
collection were subjected to Analysis of Variance (ANOVA). Results indicated
absence of nematode in the roots and none function galled roots in all the
lines. The result of the gall index Analysis showed that all the breeding lines
had gall index of zero indicating immunity of the lines to the pathogen using
gall index as indicator of plant damage. The cowpea lines reacted differently
to the yield parameters measured. These breeding lines may be important to
plant breeders interested in nematode resistance cowpea research.
