Description Field experiments were conducted at Main Agricultural Research Station, University
of Agricultural Sciences, Dharwad during kharif and rabi seasons of 2005, to find out the
seasonal influence on productivity potential in mothbean genotypes. During both seasons, 18
genotypes were evaluated for various morpho-physiological, growth biophysical,
biochemical, yield and yield components. The experiments were laid out in randomized block
design with three replications. Significant differences were observed in all parameters studied
during both seasons.
The high yielding genotypes possessed significantly higher plant height, number of
branches, number of nodes compared to low yielding genotypes besides having higher values
for LAI, CGR, LAD and BMD.
These genotypes were also efficient with respect to production and partitioning of
total dry matter. Significantly higher photosynthetic rate and nitrate reductase activity were
also recorded in high yielding group. The important yield components i.e. number of flowers,
pods, seeds per pod, 100-seed weight were significantly higher in high yielding group. All the
above traits recorded significant positive association with seed yield.
The important morpho-physiological traits associated with higher production in
mothbean are higher plant height, higher TDM, LAI, CGR, LAD, BMD, photosynthetic rate,
nitrate reductase activity, number of seeds per pod and 100-seed weight. These traits may be
considered important for developing an ideotype concept in mothbean. Among the genotypes
RMM-12 (branch) and RMM-104 were found physiologically efficient and possessed
significantly higher values for all the above traits during both seasons and may be used as a
genetic source for improvement of yield potential in mothbean.
