Abstract

Analysis of variance for combining ability in 6-parent diallel
(excluding reciprocals) of durum wheat (Triticum durum, Desf.)
revealed the following results. Desirable heterosis values over better
parent were observed for some cross combinations for all the studied
traits; plant height, days to heading, days to maturity, No. spikes / plant,
No. kernels / spike, 1000 kernel weight and grain yield / plant. The
analysis of variance for combining ability showed that mean squares
due to general combining ability (GCA) as well as specific combining
ability (SCA) were highly significant for all studied traits indicating the
importance of both additive and non-additive gene effects with the
preponderance of non-additive type of gene effects for yield and most
of its components.
