ΕΛΕΓΧΟΜΕΝΗ ΜΑΖΙΚΗ ΚΥΨΕΛΩΤΗ ΕΠΙΛΟΓΗ ΓΙΑ ΑΠΟΔΟΣΗ ΣΤΙΣ ΔΙΑΣΠΩΜΕΝΕΣ ΓΕΝΕΕΣ ΕΝΟΣ ΑΠΛΟΥ ΥΒΡΙΔΙΟΥ ΚΑΛΑΜΠΟΚΙΟΥ (ZEA MAYS L.)

CONTROLLED MASS SELECTION WITHOUT COMPETITION (E.M.E.E.A.) AND UNDER COMPETITION (E.M.E.Y.A.) APPLIED, TOGETHER WITH UNCONTINUED PEDIGREE SELECTION (Γ.Ε.Ε.Α. AND Γ.Ε.Υ.Α.), ΙΝ ΤΗΕ F4, F5 AND F6 OF THE SINGLE MAIZE HYBRID Ι.Σ.027 (ZEA MAYS L.). ALL SELECTIONS WERE IN HONEYCOMB DESIGNS, WHERE THE PLANTS WERE 1,25M APART IN THE CASE OF Ε.Μ.Ε.Ε.Α. ΑΝΔ Γ.Ε.Ε.Α.,AND AND 0,55M IN THE CASE OF Ε.Μ.Ε.Υ.Α. AND Γ.Ε.Υ.Α. THE MAIN GOAL OF SELECTION WAS THE INCREASE IN GRAIN YIELD BY SELECTING FOR YIELD ON INDIVIDUAL PLANT LEVEL. YIELD TESTS OF SELECTIONS WERE MADE IN FIELD TRIALS WITH FOUR REPLICATIONS AND WITH A DENSITY OF 5.333 PLANTS PER STREMA. ALL YIELD COMPARISONS WERE MADE IN RELATION TO F1 OF THE SINGLE MAIZE HYBRID Ι.Σ. AFTER THREE CYCLES OF E.M.E.E.A. APPLIED INTO F4, F5 AND F6 GENERATIONS, THE TOTAL WAS EQUAL TO 14,97% OF THE F1. THE ANNUAL YIELD INCREASE AND THE REGRESSION COEFFICIENT ESTIMATED 4,99% AND 5,09% RESPECTIVELY. AFTER THREE CYCLES OF E.M .E.Y.A. APPLIED INTO F4, F5 AND F6 GENERATIONS, THE TOTAL YIELD INCREASE, WAS EQUAL TO 17,44% OF THE F1. THE ANNUAL MEAN YIELD INCREASE AND THE REGRESSION COEFFICIENT ESTIMATED 5,85% AND 5,83% RESPECTIVELY.
