This study evaluates yield formation and breeding efforts in durum wheat grown in Morocco by the mean of path coefficient techniques based on plant ontogeny. A field experiment was conducted during 2008-2009 growing season with six Moroccan durum wheat varieties released between 1984 and 2007. Results obtained showed an increased grain yield from old to moderns varieties that was mainly due to longer vegetative period and heavy grains. Path coefficient analysis elucidates the correlation studies, and showed that grain yield was dependent on their three main components from old to modern varieties. Absolute and relative genetic gains in grain yield was 23 kg ha
Author Keywords: Path analysis, breeding, genetic gain, durum wheat, Morocco.

Results obtained showed an increased grain yield from old to moderns varieties that was mainly due to longer vegetative period and heavy grains. Path coefficient analysis elucidates the correlation studies, and showed that grain yield was dependent on their three main components from old to modern varieties.
