breeding lines.
1 Results
Analysis of variance shows that breeding lines were significantly different (p<0.05 and p<0.01) for all characters
under study (Table 1). Variability among the breeding lines for the characters measured was also estimated using
Duncan Multiple Range Test (DMRT) (Table 2). Breeding line code 20 was early to flower and mature (48 and
144 days, respectively). Breeding line code 23 (code≠hereafter) had the maximum height (231 cm) while code≠50
recorded the least height (149.5 cm). The maximum number of primary branches/plant (11.2) was recorded by the
code≠27, where as the maximum number of secondary branches/plant (18.8) was obtained by the code≠64.
Code≠64 had also recorded the highest number (248) of pods/plant. The maximum yield/plot was recorded by
code≠48 (1 291 kg/ha) followed by code≠25 (1 277.4 kg/ha) and code≠64 (1 102.1 kg/ha). The highest 1 000 seed
weight was recorded by the code≠53.
