Η ΑΠΟΤΕΛΕΣΜΑΤΙΚΟΤΗΤΑ ΤΗΣ ΕΠΙΛΟΓΗΣ ΓΙΑ ΑΠΟΔΟΣΗ ΣΤΟ ΚΑΛΑΜΠΟΚΙ (ZEA MAYS L.) ΟΠΩΣ ΕΠΗΡΕΑΖΕΤΑΙ ΑΠΟ ΔΙΑΦΟΡΟΥΣ ΠΑΡΑΓΟΝΤΕΣ

MASS AND PEDIGREE HONEYCOMB SELECTION SCHEMES WHICH USE EXPERIMENTAL DESIGNS BASED ON THE PRINCIPLES OF THE MOVING GRID AND THE MOVING REPLICATE AND VERY WIDELY-SPACED SINGLE PLANTS AS TESTING AND SELECTION UNITS HAVE BEEN DEVELOPED IN AN EFFORT TO INCREASE EFFICIENCY IN PLANT BREEDING. THE PURPOSE OF THIS INVESTIGATION WAS TO DETERMINE THE EFFECTS OF THE TWO HONEYCOMB SELECTION SCHEMES APPLIED AT TWO PLANT SPACINGS AND AT HIGH INDIVIDUAL AND FAMILY SELECTION PRESSURES ON THE EFFICIENCY OF SELECTION FOR YIELD AS WELL AS TO EVALUATE CONCOMITANT CHANGES IN EIGHT AGRONOMIC TRAITS IN MAIZE. IN 1983 THE FIRST CYCLE (C1) OF MASS HONEYCOMB SELECTION WAS APPLIED AT A SELECTION PRESSURE OF 1% IN THE F2(C0) OF A SINGLE-CROSS HYBRID PIONEER (PR) 3183 GROWN AT A 125 CM PLANT SPACING. THE RESULTING F3 FAMILIES WERE GROWN IN TWO SEPARATE REPLICATED HONEYCOMB EXPERIMENTS IN 1984 AT DIVERGENT PLANT SPACINGS OF 125 AND 40 CM. (SHORTENED)
