Standardized correlations and path-coefficient analysis for seed yield in four populations of Egyptian multi-cut barseem clover "Trifolium Alexandrinum, L."

الملخص EN

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 .
