Abstract
Seed quality plays an important role in the crop establishment and overall performance of the
crop. With an array of possible viability and vigour tests available, appropriate procedure to evaluate
seed performance is a very difficult job but a necessity. Keeping this aspect in view present
investigation was carried out to evaluate seed quality of three varieties of okra and comparative efficacy
of seed viability and vigour test as predictor of field emergence.
Seeds of three varieties seeds obtained from summer and rainy season crop were subjected to
various viability and vigour tests with four replications and observations were recorded on standard
germination, dehydrogenace activity, tetrazolium test, seedling length, speed of germination, test
weight, standard germination after accelerated ageing, seed density, seed vigour, seedling dry weight,
field emergence and seedling establishment. Results revealed that, among varieties tested, Varsha
Uphar was significantly superior to Hisar Naveen and BB-1 in all above quality parameters. The seeds
obtained from rainy season were superior from the seeds obtained from summer season.
All the parameters were significantly correlated with field emergence (except dry weight of
seedling, seed density and dehydrogenace activity). The electrical conductivity was significantly and
negatively correlated with field emergence. Standard germination followed by vigour index-II showed
highest reliability for prediction of field emergence. Correlation coefficient analysis and regression
analysis revealed that viability and vigour parameters like standard germination, seed vigour,
tetrazolium test, seedling length and electrical conductivity can be used as reliable predictor of field
emergence in okra.
