This investigation was carried out at the Experimental Station Farm. Faculty
of Agriculture. Alexandria University at Abies region. in four successive seasons. from
1998 till 2001. At the first season, the various characteristics of five parental cutivars of
sweet pepper were evaluated by measuring their mean, coefficient of variation (C.V.)
and range. Two cycles of inbreeding were performed on individual true type plants of
the parental cultivars for genetic purification of their characters. Hybridizations among
plants of the 5 parents were performed in one way diallel fashion without reciprocals.
The data of 15 genotypes of the characters of yield-and quality-components were
subjected to combining ability analyses . Mean performance and heterosis to the
better parent as well as the.effects of general - and specific- combining ability were
counted for the important characters for the various studied genotypes of sweet
pepper.
