fruit weight only , whereas , the negative indirect
effect through date of flowering, no. of branches
, and no. of fruit plant -1 . These results concurred
with Allam and Malik (1987) who found a
positive indirect effect on the plant yield. It is
obviously appear a positive low direct effect of
number of branches on the total yield measured
(0.064), and it had low positive indirect effects
through date of flowering, and high through
fruits number plant -1 whereas, it had a negative
indirect effect through plant height fruit weight.
These result are inconformity with Nadar (1980),
AL-hubaity (1996) who found that no. of
branches plant -1 had higher indirect effect on the
yield of tomato plant. On other hand , number of
fruits appeared to have a very high positive
direct effect (1.478) , and it had low positive
indirect effect through date of flowering and no.
of branches , while an indirect effect was highly
07
negative through fruit weight ( - 0.815) and low
through plant height ( - 0.027) . Similar results
were reported by Srivastava and Udaipur (1973)
in tomato, Singh, Nandpur et al. (1977b) and
AL-hubaity (1996) in tomato, who emphasized
that number of fruits plant -1 was the main
component of yield.
As for the average fruit weight, it had a high
positive direct effect (0.931) on the yield,
whereas, it showed a low positive indirect effect
through the remnant traits recorded (- 0.139, -
0.033, - 1.293) for date of flowering , no. of
branches and no. of fruits respectively .
The breeder can be used highest direct
effects were resulted from no. of fruits and fruit
weight, indirect effects of fruit weight through
date of flowering and no. of fruits through
branches number in breeding program.
