The present study was conducted to assess the magnitude of variability among twenty-four
different quantitative traits in Okra germplasm. The analysis of variance revealed high
significant differences for all characters under study. High GCV and PCV noticed for YVMV
Infestation on Fruits, Co-efficient of YVMV Infection, YVMV Infestation on Plants, Severity of
YVMV Infestation, FSB infestation on fruits, marketable yield/plant, FSB infestation on
shoots, total yield/plant, marketable fruits/plant, branches/plant, leaves/plant and seeds/fruit.
High heritability (h bs) was observed for all characters studied. High genetic gain coupled
with high heritability recorded for YVMV Infestation on Fruits (%), Severity of YVMV
Infestation, Co-efficient of YVMV Infection, FSB infestation fruits, marketable yield/plant,
FSB infestation on shoots, total yield/plant, marketable fruits/ plant, branches/plant,
leaves/plant, seeds/fruit, fruits/plant, fruit weight, 100 seed weight, plant height, internodal
distance and first flowering node indicating the role of additive genetic variance in the
expression of these traits. Thus, these traits may serve as an effective selection parameter
during breeding programme for crop improvement. Based on the mean performance for pod
yield, yield component traits and relative resistance to YVMV and FSB, genotypes
2012/OKYVRES-5,
2012/OKYVRES-6, 2012/OKYVRES-2,
10/OKYVRES-2
and
10/OKYVRES-3 found superior in performance than check varieties. These could be used as
parental material in further crop improvement program after considerable selection to fix the
desirable traits.
