Genetic variation for seed yield components in jute (Corchorus Spp.)

Published on

Seven varieties comprlsmg four tossa jute (Corchorus
olitorius L) and three white jute (Corchorus capsularis L)
were evaluated for seed yield and its components viz.
pod length, girth of pod, number of filled seed, 100-seed
weight in 1998 and 1999. The varieties exhibited significant
differences for all traits except pod girth. The variety
x year interactions were not significant for pods harvested
from bottom position of the branches, for number of filled
seeds and 100-seed weight indicating that these three
components are reliable for producing good seed yield.
The number of filled seeds per pod is uniformly distributed
in capsularis while in olitorius it is declined from bottom
to top position of the pods on branches. However, in
both species pods harvested from top position of branches
had significantly lower 100-seed weight compared to
bottom and middle positions of pods on branches. The
high values for PCV and GCV for pod length, pod girth
and number of filled seed'> suggest that there is a
possibility of improving seed yield through direct selection
for these traits. Number of filled seeds and lengths of
pod were strongly correlated with seed yield in pod
harvested from bottom and middle position along the
