Abstract
The present investigation on " Seed Quality Studies In Soybean
(Glycine max (L.) Merrill )" was carried out with an aim to identify proper
stage of seed harvest to obtain high seed quality in relation to seed germination and seedling vigour components and correlation & path analysis for seed
quality characters in soybean. To identify the proper stage of ~arvest the seed
of five genotypes viz. JS 335, JS 93-05, MAUS 71, MAUS 81 and MAUS I 58
were grown in Factorial Randomized Block Design (FRBD) with three
replications and eleven characters viz., moisture content, seed index,
processing recovery, oil content, protein content, seed germination, vigour
index, shoot length, root length, seedling fresh weight and seedling dry weight
were studied.
The genotypes MAUS 158 performed better than all genotypes in
respect of protein content, oil content and germination percentage. Most of the
characters I ike seed moisture, seed germination, vigour index and oil content
decreased after physiological maturity stage. l-Ienee it is advisable to harvest
the soybean crop at physiological maturity for better seed quality.
The correlation study revealed that moisture content showed a
significant and negati vely correlated with germination whi le the seed index ,
processing I·ecovery and oil content were significant and positively correlated.
protein content showed positive correlation with germination and oil & protein
content were positively correlated. The moisture content recorded highest
negative direct effect on seed germination while seed index, processing
recovery and oil content showed significant positive indirect eff'ect.
