Standardized Correlations and Path-Coefficient Analysis for Seed Yield in Four Populations of Egyptian Multi-Cut BarseemClover'Trifolium Alexandrinum,L.'

摘要

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-1in 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"'.
