Description Sixty-seven germplasm lines of okra [Abelmoschus
esculentus (L.) Moench] of diverse eco-geographical origin
were undertaken in present investigation to determine the
genetic divergence following multivariate and canonical
analysis for fruit yield and its eight component traits. The 67
genotypes were grouped into five clusters depending upon
the genetic architecture of genotypes and characters
uniformity and confirmed by canonical analysis. Eightynine
per cent of total genotypes (60/67) were grouped in two
clusters (I, II), while apparent diversity was noticed for 11%
genotypes (7/67) that diverged into three clusters (III, IV and
V). The maximum intercluster distance was noticed between
IV and V (23.38), followed by III and V (21.46), I and V
(16.84). The cluster IV was very unique having genotypes of
high mean values for most of the component traits.
Considering high mean and inter cluster distance breeding
plan has been discussed to select desirable plant types.
