Abstract:
The general combining ability
was the best general combiner for plant height at last harvest, number of flower cluster per plant, fruit size
exhibited highest GCA effect for
individual fruit weight, number of seed per fruit, P
6
5
showed highest GCA effect for number of fruit per
plant, P
2
and P
8
were the best general combiner for earliness and parent P
showed highest significant
positive GCA effect for fruit yield per plant although fruit size of this parent is not good enough. The
highest SCA effect and heterosis over mid parent for earliness was observed in the cross combinations P
× P
8
1
which also showed best heterosis over mid parent for earliness, fruit breadth and number of seed per
fruit. Cross combination P
8
× P
showed the highest SCA effect and higher mid parent heterosis for the
highest plant height at last harvest and for plant height at last harvest; flower cluster per plant and TSS% ;

for number of seed per fruit
and mid parent heterosis for fruit breadth; the highest SCA and mid parent heterosis observed in P
for fruit length; P
