Dry matter production at different growth phases and its variability in Corchorus capsularis L.

Published on

Pattern of dry matter distribution within different plant parts
in 15 genotypes of Corchorus capsularis jute was estimated.
Significant differences for distribution of dry matter were
observed. Linear increase in dry weight of root, leaf and
stem was recorded following the progress of growth period
in most of the genotypes. Consistent superiority with
respect to dry matter production in root, leaf , stem and
bark with high bark to stick ratio was shown by CEX 040.
On the other hand, CEX 048 had highest dry seed and pod
weight. CEX 040 and CEX 048 can be recommended for
commercial production of fibre and seed respectively. Least
environmental influence was observed in partitioning of
dry matter. Various components for fibre yield was
predominantly controlled by additive gene action and that
for seed by both additive and non additive gene actions.
Dry matter in bark showed significant positive correlations
with that of root at 120 days, leaf at 60 days, stem at 90 and
120 days whereas seed weight showed similar relationship
with pod weight, leaf dry weight at 90 days and stem dry
weight at 60 and 90 days.

Keywords: Dry matter, Corchorus capsularis, coefficient of variation, heritability, genetic advance, correlation coefficient.
