Positive heterosis was present for the number of flowers/mainretem. The three crossea N A 112 x Giza 2, N A 112 x Giza 3 and
r 61/536/69 NEB 319 exhibited significant negative heterosia for
shedding percentage. General and specific combining ability (GCA
rand SCA) were significant for the number of flowers/flaifl
Btem,number of pods/main stem and shedding percentage. High values
rof GCA/SCA were also obtained for the three traits. Line N A 112
seems to be the best combiner for low shedding percentage and li
‘ 61/536/69 and Giza 3 for high number of flowers and pods/main stem.
SCA effects for low shedding percentage was manifested in the
‘ three crosses; N A 112 x Giza 2; N A 112 x Giza 3 مnd N A 112 x
Sevella gaint. The cross Giza 3 x 61/536/69 exhibited. the highest.
SCA effects. for higher number of flowers/main stern. Low
heritabi1ity estimates were obtained for the three tante. The ad—
ditive (D) and dominance components (H1) were significant for the
number of flowers and pods/main stem. The overall dominance of
heterozygOUs loci (H2) was significant for the three traits.
The correlation of parental means and their order of dominance
shows that increaser genes were dominant over decreasers for number
of flowers and shedding,afld few number of pods was dominant over
‘: high ones. As for parental lines, the line N A 112e contains most ,
“ of the dominant genes responsible for high number of flowers and
low shedding. NEB 319 contains most of the recessive ones. Giza 3
contains most of dominant genes for high number of pods/main stem,
meanwhile, N A 112 contains the most recessive ones.
