which growth and vigour of plants are measured. In
F
1
hybrids, B-3-8-8×OBG-31 (26.63) was tallest
among all the crosses followed byOBG-31×Keonjhar
Local (26.47) and LBG-17×Keonjhar Local (26.23).
Plant height is a major quantitative character which
governed yield/plant (Table 7). The range of
sca
for
plant height varied from -2.72 to 3.69. The cross
OBG-17×PU-30 had the lowest
sca
value of -2.72
which indicated the cross combination resulted the
plant type which was shortest among all followed by
B-3-8-8×PU-35 (-2.20) and OBG-17×OBG-31 (-1.94)
(Table 8).
Number of primary braches/plant
Keonjhar Local had maximum number of primary
branches/plant (1.62) followed by TU-94-2 (1.56) and
OBG-31 (1.50), lowest number of primary branches/
plant was recorded with PU-30 (1.31) followed by
LBG-17 (1.26) (Table 5). For this character the
gca
effect was ranging from -0.09 to 0.09. Keonjhar Local
(0.09)exhibited significant positive general combining
ability effects for number of primary branches/plant
followed by OBG-31 (0.06). The lowest
gca
effect
was recorded with the parent B-3-8-8 (-0.09) followed
by PU-30 (-0.04) (Table 6). The F
1
hybrid recorded
with the highest number of primary branches/plant
was PU-35×Keonjhar Local (1.67) followed
byLBG-17×OBG-31 (1.67) and LBG-17×Keonjhar
Local (1.60). B-3-8-8 × TU-94-2 (1.18) had the lowest
number of primary branches/plant among all the
entries made (Table 7).The range of
sca
for number of
primary braches/plant lies with -0.14 to 0.21 whereas
B-3-8-8×TU-94-2 (-0.14) had lowest
sca
effect
followed byPU-30×PU-35 (-0.12) whereas LBG-17×
OBG-31 had highest
sca
effect (0.21) followed by
PU-35×Keonjhar Local (0.17) and TU-94-2×PU-30
(0.16) for number of primary branches/plant (Table 8).
Number of clusters/plant
PU-30 exhibited lowest values for number of
clusters/plant (5.36) followed by LBG-17 (5.44)
whereas the maximum number of clusters/plant
exhibited by Keonjhar Local (5.73) followed by
OBG-31 (5.72) (Table 5). Among 8 parents 4 parents
exhibited positive
gca
effect (3 were significant) for
this character whereas rest 4 parents exhibited
negative
gca
effect (2 were significant). OBG-17
(0.12) and TU-94-2 (0.12) exhibited significant
positive general combining ability effects for number
of clusters/plant. Whereas negative
gca
was recorded
withPU-30 (-0.17), LBG-17 (-0.11) indicated this
genotypes were not suitable for selection of this traits
(Table 6). For number of clusters/plant the F
1
hybrid
TU-94-2×OBG-31 (6.14) had maximum ranking than
all other hybrids followed by TU-94-2×PU-30 (6.06)
and PU-35×Keonjhar Local (6.05). PU-30×OBG-31
(4.48) had lowest number of clusters/plant (Table 7).
The range of
sca
effect for this character varied from
-0.85 to 0.62. The best specific combiner among the
entire 28 F
1
hybrid was PU-35×Keonjhar Local (0.62)
followed by TU-94-2×PU-30 (0.61) and TU-94-2×
OBG-31 (0.53) whereas the lowest
sca
effect for this
character was recorded with the cross PU-30×
OBG-31 (-0.85) followed by PU-30×Keonjhar Local
(-0.67) (Table 8).
Number of pods/plant
Number of pods/plant was maximum with TU-94-2
(24.89) followed by PU-35 (24.77) and OBG-31
(24.73) and the lowest number of pods/plant was
recorded with B-3-8-8 (22.29) followed by Keonjhar
Local (23.85) (Table 5). A study of the
gca
effects of
the parents for this character showed that OBG-31
(0.73) and Keonjhar Local (0.35) exhibited strong
positive effect than other genotypes with respect to
this character. Whereas the genotypes like B-3-8-8
(-0.81) and PU-30 (-0.27) were significantly differing
from OBG-31 with regards to number of pods/plant
(Table 6). The positive
gca
effect is desirable for
selection parent for this character.OBG-31×Keonjhar
Local (26.99) had the highest pods/plant among all 28
F
1
hybrids followed by OBG-17×Keonjhar Local
(26.77) and TU-94-2×PU-30 (25.86). The lowest
pods/plant was observed with hybrid OBG-17× PU-35
(22.53) (Table 7). OBG-17×Keonjhar Local (2.26)
exhibited significant highest
sca
effect for this
character followed by OBG-31×Keonjahr Local (1.70)
and TU-94-2×PU-30 (1.69). The
sca
for this character
varied from -1.56 to 2.26. The significant lowest
sca
was recorded with OBG-17×PU-35 (-1.56) followed
by TU-94-2×PU-35 (-1.21). Positive significant
sca
favours the selection this character (Table 8).
Number of seeds/pod
Maximum number of seeds/pod was resulted with
OBG-31 (6.17) followed by PU-35 (6.00) and PU-30
(5.75) whereas lowest seeds/pod was recorded with
LBG-17 (5.32) followed by TU-94-2 (5.45) (Table 5).
