The objective of the present study was to determine through path-analysis the significant role of seed yield
components in the yield of barseem seed, their interrelationships and relative importance, considering four variable
population. In all studied multi-cut barseem populations, number of heads.plant-1 was the most positively correlated trait
with total seed yield. While, seed weight.head-1 was of moderate correlation with total seed weight in three out of the four
populations (Alexandria I, Meskawi and Helaly). Also number of seeds.head-1 was of moderate positive correlation with
total seed weight in only two populations (Meskawi and Helaly). The strongest positive correlation was expressed
between number of seeds.head-1 and seed weight.head-1 in all studied barseem populations. This latter results might
indicate that seed weight.head-1 might influence the total seed yield through number of seed.head-1.
