Many
produce
earliness and minimal shedding pods and
flowers caused by stormy weather
prevailing in February. Few studies are
available in the literature on gene action
of shedding in field bean which affects
yield and its components.
The present study was carried out to
estimate the types of genetic variance
components and their interaction by
environments for number of flowers per
main stem, percent shedding of flowers,
percent pod shedding and total percent
shedding in field beans.
MATERIALS AND METHODS
The parental varieties or lines in this
study were NA 112, ،.155, ،.54,
F.70/41/808, Moshtohor-1. Half diallel
efforts are being made to
varieties characterized by
crosses were made among these five
parents during the 1982/83 and 1983/84
seasons. The five parents and their
hybrids were grown in a randomized
complete block design with three
replications in both 1983/1984 and
1984/1985 at the Agricultural
Experiment Station, Moshtohor, Egypt.
The characters studied were:
1- Number of flowers on main stem
2- Percent shedding of flowers on main stem
= no. of flowers - no.of young set pod X1Œ)
no.of flowers
3- Pod shedding percent =
no. of young set pods-no.of mature podsXlOO
no. of young set pods
4-Total shedding percent =
no.of flowers - no. of mature pods X100
no.of flowers
The data were recorded from the
main stem of ten guarded plants per plot.
