EFFECT OF SEED SIZE ON GROWTH AND YIELD TRAITS IN DURUM WHEAT(TRITICUM DURUM L.).

Progenies raised from bigger seeds of the same genotype were taller, had more leaves, more tillers and higher grain yield than their small seeded counterparts. Differences during growth period between seed categories were also recorded for leaf area, number of leaves, tillering and plant height at different growth stages. Higher grain yield resulted mainly from a greater number of heads on plants grown from large seeds. [ABSTRACT FROM AUTHOR]
