Abstract
The half diallel set of crosses among six inbred lines of faba bean was
performed at Terbol Research station, International Center for Agricultural
Research in The Dry Areas (ICARDA), Lebanon. during 2013-2014 growing
season, the resulted crosses and their parents were evaluated in 2014-2015 to 3
study the genetic indices: heterosis, correlations among traits and path
coefficient analysis for grain yield and it's components, days to flowering and
protein content. the results was indicated that heterosis compared to mid and
better parents was significant for all traits in all crosses under research,
Heterosis effects for grain yield varied between 14.3% -184.55% and 0.84% -
176.31% relative to mid and better parents respectively. Correlation coefficients
between traits indicated that grain yield was positively and significantly
associated with pods per plant (0.947**), protein content (0.328**) and seeds per
pod (0.257**), negatively and significantly associated with days to flowering (-
0.265*
). The path coefficient analysis estimates showed that pods per plant, days
to flowering and protein content can be considered as the most important
contributed characters in grain yield variation.
